Protecting our plants from thirp damage…

download (1)Found in a rainbow of North American plants from avocados to beans, onions, citrus trees and market flowers, thrips are tiny insects. These species that are plant feeders can scar leaf, flower or fruit surfaces with silvery speckling when they puncture and suck out the cell’s content. Conversely, heavy pest populations can severely distort flowers and damage fruit. Other thrip species function as beneficial insects by eating mites, fungal spores and pollen.

When thrips have fed on a bud, it will often fail to open; or if it does open, the flower will be deformed. Flowers upon which the thrips feed may also become streaked and/or discolored. When thrips feed on plant leaves, the leaves will dry out and appear speckled with silvery flakes. The leaves will eventually wilt and fall off.

To lay its eggs, the female thrip will make a slit in a leaf then lay 25 to 50 eggs within it. The eggs can develop into adults within three weeks, or sooner for some species. Many species of thrips also reproduce asexually. They can produce many generations in a single season.

In addition to damaging and feeding on plants, thrips are known to bite humans. They can cause both skin and respiratory irritation to people, according to the University of Michigan, particularly to workers in fields where infestations exist.

downloadThrips are small insects, only about 1/20″, but they can cause a lot of damage. At maturity, they are yellowish or blackish with fringed wings.  Nymphs have a similar shape but lack the wings. They are usually yellowish to white. Thrips are poor flyers. As a result, damage often occurs in one part of the plant then slowly spreads throughout it.

images (1)Thrips feed in buds, folded leaves, and other unexposed areas of plants. This makes them difficult to treat with an insecticide. They feed by sucking juices from the plant causing stippling, or small scars, on leaves, flowers and fruit. This results in stunting of the plant, leaf distortion and premature leaf drop. Flowers may be deformed and fail to open properly. Petals may show brown streaks and spots. Their excrement is black and shiny, which may be a clue to their presence.  In addition to this physical damage, thrips also transmit tomato spotted wilt virus and impatiens necrotic spot virus, for which there is no control.

If enough thrips attack a plant, the leaves may take on a silver streaked appearance. When there is a large enough infestations of thrips, the plant can be severely damaged. Fruits will not be able to fully mature.

imagesIn many species, thrips feed within buds and furled leaves or in other enclosed parts of the plant. Their damage is often observed before the thrips are seen. Discolored or distorted plant tissue or black specks of feces around stippled leaf surfaces are clues that thrips are or were present. However, some abiotic disorders, pathogens, and certain other invertebrates can cause damage resembling that of thrips. For example, lace bugs, plant bugs, and mites also stipple foliage, and lace bugs and certain plant bugs produce dark, watery fecal specks. Look carefully for the insects themselves to be certain that pest thrips are present and the cause of damage before taking control action.

Thrips are poor fliers but can readily spread long distances by floating with the wind or being transported on infested plants. New thrips introductions can pose serious threats and complicate identification. A recent introduction of Klambothrips myopori has caused serious leaf and shoot galling damage to Myoporum laetum(ngaio tree) and Myoporum ‘Pacificum’ (a groundcover) along the coast of California. This thrips was both a new introduction and an undescribed species, so that initially not even the experts knew what to call it or how it might be managed. This species is now well established and from its original detection site in San Diego has spread north along the coast to at least as far as Santa Barbara. It is expected to continue to spread to wherever Myoporum species have been planted.

Thrips prefer to feed in rapidly growing tissue. Feeding by thrips typically causes tiny scars on leaves and fruit, called stippling, and can stunt growth. Damaged leaves may become papery and distorted. Infested terminals may discolor, become rolled, and drop leaves prematurely. Petals may exhibit “color break,” which is pale or dark discoloring of petal tissue that was killed by thrips feeding before buds opened. Thrips cause silvery to brownish, scabby scarring on the avocado and citrus fruit surface, but this cosmetic damage does not harm the internal fruit quality. Feces may remain on leaves or fruit long after thrips have left. Where thrips lay eggs on grapes, dark scars surrounded by lighter “halos” may be found on the fruit. Thrips feeding on raspberries, apples, and nectarines can deform or scar developing fruit; sugar pea pods may be scarred or deformed. Citrus thrips feeding severely distorts blueberry shoot tips and foliage, reducing fruit yield.

Western flower thrips are primarily pests of herbaceous plants, but high populations occasionally damage continuously- or late-blossoming flowers on woody plants such as roses. Some plant-feeding thrips are also predaceous on other pests, such as spider mites. In young cotton seedlings in California, western flower thrips is considered beneficial because it feeds on spider mites.

Behavior, body appearance, and host plants help to distinguish among thrips species. For example, three dark spots on each forewing distinguish the adult predaceous six spotted thrips from pest thrips. Adults of western flower thrips and onion thrips, are noticeably larger than avocado and citrus thrips adults, so mature body size helps to distinguish them when they occur together on the same host plant. However, thrips can be positively identified to species only by an expert. Fortunately, most thrips are susceptible to some of the same controls, such as exclusion and pesticides.

It is more important to distinguish among thrips species in situations where integrated pest management methods are used. For example, predatory thrips or other natural enemies are highly specific to certain pests and are likely to help control only certain species of plant-feeding thrips. Certain thrips occur on many different plants but damage only a few of the plant species on which they are found, so identifying the thrips species may reveal that it is harmless in that situation and no control action is needed. For example, avocado fruit skin is scarred by avocado thrips and greenhouse thrips, but citrus thrips and western flower thrips are harmless in avocado. Citrus thrips occurs on many species of plants but damages only blueberries and citrus.

Although thrips damage to leaves is unsightly, thrips activity does not usually warrant the use of insecticide sprays. For instance, while thrips damage on citrus or avocado fruit may look unpleasant, it does not harm trees or affect the internal fruit quality. When damage is noticed on ripening fruit or distorted terminals, the thrips that caused the injury are often gone. It’s not until later when tissue grows and expands that injury caused earlier becomes apparent. While viruses vectored by thrips may cause plant loss, insecticide sprays are not recommended to prevent viruses because thrips are not killed fast enough to prevent the transfer of the virus to new plants. Prevention of thrips infestations is the only way to prevent infection by thrips-vectored viruses.

Banana Skipper destroying banana plantations!

Banana skipper (Erionota thrax) butterfly is from South East Asia, where the MG_9952acaterpillars (larvae) cause the major damage to infested plants. This pest is also known as the banana leaf roller or palm redeye. After hatching, the caterpillars move towards the outer edge of the leaf where they feed and roll the leaf to make a shelter. Within the roll the larva secretes a protective, white, waxy covering. The feeding and rolling destroys the leaves, significantly reducing the plant’s leaf area and leading to reduced fruit production, as well as preventing the use of the leaves for traditional purposes. The adult female lays small yellow eggs in batches of 12–25 on lower leaf sides, from which the caterpillars emerge. Caterpillars roll up banana leaf sections and eat the leaves as they grow. They also exude a fine white powdery material over their body. Adult butterflies are brown with three yellow-white areas at the front of their wings. They have a wingspan of around 7cm.

Banana skipper butterflies have brown bodies with large heads, large red eyes and thickened, curved antennae tips. Each wing is 31-37 mm wide, with three yellow areas on the forewings. Banana skipper butterflies are called skipper butterflies due to their fast, darting flight movements. They are attracted to light.

UntitledThe skipper larvae are present in the rolled-up sections of leaves. Unroll the leaf curls and check for the presence of the caterpillars and/or their white powdery covering. Banana skipper caterpillars damage banana plants by feeding on and rolling up the leaves. The caterpillars can damage 60% of the plant leaf area. Leaf damage lowers banana yields due to delayed fruit maturity and reduced bunch size. The adult butterflies are most active in the early evening and are not commonly seen.

Banana skipper is currently widespread in South East Asia, and is also found in Papua New Guinea, Mauritius, Guam and Hawaii. They were particularly devastating to banana crops in Papua New Guinea in the 1980s. Its close MG_9977aproximity to northern Australia is a concern to the Australian banana industry.

Banana skipper butterfly infests cultivated and wild bananas (Musaceae). They can spread longer distances as eggs on the leaves of infested banana propagation material or as undetected butterflies on boats, vehicles or aircraft.

Let’s take a look at the following article on the damage done by banana skipper;

Banana farmers reel under ‘butterfly’ attack

NANDAKUMAR, July 7, 2014

 Scientists at the Kerala Agricultural University have called for heightened vigil against a new and devastating pest that threatens to blight banana crops in the State.

The pest, identified as the Banana Skipper or Palm Redeye (Erionota thrax), is a chocolate-brown butterfly belonging to the family Hesperidae. It is also known as Banana Leaf Roller because its larva or caterpillar cuts the leaves at the edges and makes a series of cylindrical rolls before developing into a pupa. A heavy infestation could damage the whole banana leaf, leaving only the midrib intact.

dwsdAccording to Dr. Arthur Jacob, Professor and Head of the KAU’s instructional farm at Vellayani near here, the pest was reported last year from different locations in the State. He said the damage was now found to be spreading to the southern parts, especially Thiruvananthapuram, a major producer of banana. The infestation has been found to be heavy in a few banana farms at Kalliyoor, Kakkamoola and Pallichal near Vellayani.

Originally reported from Southeast Asia, the banana leaf roller pest is distributed in Northeast India, Sikkim, Nepal, the Andaman islands, Mauritius, Malaysia, China, Vietnam, Hawaii and Papua New Guinea. Measuring 4 to 6 cm in length, the white powder-coated caterpillar prefers banana leaves though it is occasionally found to infest coconut palms also.

Citing reports from other countries, Dr. Arthur said natural control was the best remedy. The introduction of natural parasites has been advocated to bring the damage under control.

An expert team of the KAU has advised farmers to be vigilant against the spread of the pest. The scientists have called for field scouting and periodic destruction of the rolled leaves by burning to kill the larvae. “Chemical control measures are seldom required, but if the manual removal of the leaf rolls is not possible, treatments timed to control the newly hatched larvae may be attempted with the backing of field studies,” Dr. Arthur said.

Battling The Spotted Lanternfly- The non-toxic way!

t4An unwelcome guest has recently been plaguing the plant life in Pennsylvania. These are nothing but Spotted Laternflies, which are beautiful, colourful insects and might seem like any other nuisance bug; but which are can prove to be extremely dangerous. The invasive pest poses a threat to fruit orchards and grape vines, along with forests and the timber industry. It attacks trees by feeding on sap and harms them further by excreting large amounts of a fluid that coats leaves and stems and encourages the growth of mold, according to researchers.

The Spotted Lanternfly is about one inch long and a half-inch wide, and is native to China, India, Japan and Vietnam. The insect uses its “piercing and sucking mouthparts” to drain stems of sap while at the same time excreting a lot of liquid. Due to the sugar content of the liquid, plant parts covered with spotted lanternfly excretion harbor mold growth, which could hinder plant growth. This can reduce photosynthesis, weaken the plant, and eventually contribute to the plant’s death. In addition, feeding can cause the plant to ooze or weep. It’s described as a weak flyer but a “strong and quick jumper,” and it’s done some serious damage in Korea, where it was introduced in 2006; it has since attacked some 25 plant species that can also be found in Pennsylvania. Spotted lanternfly feeds on a variety of host plants including fruit trees, ornamental trees, woody trees, and vines.

SpottedLanternflyEgglaying - GregHooverThis pest poses a significant threat to the state’s more than $20.5 million grape, nearly $134 million apple and more than $24 million stone fruit industries. Pine and hardwood logging in Pennsylvania also accounts for $12 billion in sales. The damage caused by this pest is so much so that around 5 Pennsylvania townships and 2 boroughs are on high alert after the state Department of Agriculture confirmed the presence of an invasive insect that threatens its grape vines, fruit trees and logging industry. To date, delimiting surveys conducted by the Pennsylvania Department of Agriculture (PDA) indicate that the infested area may be approximately 30 square kilometers (11.6 square miles) in six townships and two municipalities in eastern Berks County.

The below article would aptly describe the threat posed by these pesky insects.

Invasive insect found in Berks County feeds on fruit, ornamental, woody trees

By Vincent Cotrone

November 16, 2014

The first American chestnut disappeared from our forests and landscapes in the early 1900s when an exotic fungal disease, cryphonectria parasitica, aka chestnut blight, was accidentally introduced.

Next it was American elms that we lost to an imported disease in the 1960s. More recently, we have seen imported insects such as Emerald Ash Borer killing millions of native ash trees across the Eastern United States, Hemlock Woolly Adelgid, a tiny aphid like insect, causing major declines in native hemlock, and Asian Longhorned Beetles threatening maples in New York and New England.

“When will it end?” you might ask yourself. Apparently not anytime soon, because a new invasive insect (a planthopper) named the Spotted Lanternfly (Lycorma delicatula) has just been discovered in Berks County. This pest is native to China, India and Vietnam. It attacks and feeds on many host plants including fruit trees (apples, pears, plums), ornamental trees, woody trees and vines. Apples, birch, cherry, dogwood, grapes, lilac, maple, poplar, stone fruits and tree-of-heaven are among more than 70 species of hosts attacked by this pest.

Adults and nymphs feed on phloem tissues of foliage and young stems with their piercing and sucking mouthparts and excrete large quantities of liquid. Due to the sugar content of the liquid, plant parts covered with spotted lanternfly excretion harbor mold growth, which could hinder plant growth or even cause death.

Think this is just another nuisance bug? Think again. This pest poses a significant threat to the state’s more than $20.5 million grape, nearly $134 million apple and more than $24 million stone fruit industries. Pine and hardwood logging in Pennsylvania also accounts for $12 billion in sales.

As the state Department of Agriculture tries to control the spread of this new pest by placing quarantines on the movement of plants, wood and stone materials out of Berks County, it will also be conducting surveys across the commonwealth to determine if the infestation is wide spread. This is where the home gardener and commercial landscaper or arborist comes in.

A research paper about the bug’s spread in Korea explains why it can be tough to control: “Furthermore, no natural enemy of L. delicatula seems to exist in Korea. Thus, farmers use pesticides to control them in vineyards (Park et al. 2009). However, the use of pesticides kills natural enemies of other grape pests and L. delicatula can repopulate pesticide-sprayed areas from nearby forested areas, which contain suitable host species.” Evidently, we need a solution which would prevent the spread of these insects, but at the same time not harm the beneficial pests in any way.

Rutherglen bugs- A threat to our seedlings!

toA farmer has to take into consideration a number of factors during the germination and subsequent growth of seedlings and crops. Bad weather, unavailability of nutrients and pest damage are just some of the issues that a farmer has to be prepared for. While bad weather is something that cannot be controlled no matter what, prevention or control of pest damage is one thing that farmers can take care of to make sure they get abundant produce. One such pest of agriculture is the Ruther­glen bug.  Rutherglen bugs are mainly sap suckers and may cause damage to susceptible plants in a way similar to that caused by aphids.

Rutherglen bug is best known as a seed-feeding pest, attacking grain as it develops and fills. However, in some seasons, large numbers of nymphs and adults can cause damage to establishing winter or summer crops. Their populations can build up in summer weeds, and move from these into establishing winter crop, feeding on and killing small seedlings. Large numbers of Rutherglen bugs moving out of crops poses a threat to nearby establishing summer crop. The adults migrate into fields from local weed hosts, or more distant sources in spring. Infestations can be large and the period of invasion prolonged. The damage caused by these bugs may include flower abortion, reduced pod set and seed development. Direct feeding on developing seed may affect oil quantity, quality and seed viability. These bugs can persist into windrows, and at harvest cause problems with seed flow through harvesters, and by raising the moisture content of the grain to above acceptable standard.

Heli_0290The main issue with Rutherglen bugs around harvest time is con­t­a­m­i­na­tion of harvested grain. When they are in very large numbers they can cause a number of issues at harvest; live bugs in the sample can result in rejection of a load at the delivery point. In some seasons the infestation can reach plague proportions, typically when the senescence of weed hosts in spring and early summer forces adults and nymphs into nearby crops. Although Rutherglen bug is usually a pest in spring, in rare instances large infestations have occurred in autumn with seedling crops decimated by the feeding of adults and nymphs. In very large numbers, these bugs can dam­age seedling crops purely by weight of num­bers feed­ing on seedlings. The bugs maintain their populations on fallen sunflower seeds and migrate to cotton as the seedlings emerge. They suck the cotton seedlings dry resulting in an establishment problems and gappy stands. This situation can also arise in fields with poor hygiene where weeds act as a winter host. They can also build in some winter crops such as canola and then move into adjacent seedling cotton in the spring.

The below article would further emphasize on the damage caused by these pesky creatures.

Rutherglen bugs storm northern crops

18/12/12

An infestation of Rutherglen bugs that may have ridden recent storms into the northern grains region is causing headaches for growers from northern NSW to Central Queensland.

Dr Melina Miles, Queensland Department of Agriculture, Fisheries and Forestry (DAFF) says large numbers of Rutherglen bugs have migrated into cropping regions since early November.

“While the exact origin of the bugs is unknown, it is likely they are being carried on storm fronts from inland regions where they have bred up over winter and spring on native host plants,” Dr Miles said.

“Large numbers are affecting seedling establishment, simply by weight of numbers feeding on the emerging seedlings.

64yu“In some instances the seedling crops are invaded by large numbers of nymphs walking out of weedy fallows into establishing crops.”

Dr Miles says ploughing a deep furrow between the seedling crop and the source of bugs, or a border spray may be sufficient to prevent ongoing infestation.

She says sorghum is vulnerable to Rutherglen bug from flowering to soft dough stage.

Grains Research and Development Corporation (GRDC)-supported research shows sorghum crops infested during flowering will fail to set seed, and infestations at milky dough stage will result in seed covered in small, dark feeding wounds.

Dr Miles says developing grain affected by Rutherglen bug feeding is light in weight, with poor germination. Under wet conditions, fungal and bacterial infections further degrade Rutherglen bug-damaged grain, infecting through feeding wounds on the seed.

If large num­bers of Rutherglen bug move into the estab­lish­ing crop, insec­ti­cide seed dress­ings will not pre­vent dam­age to seedlings, as each bug must feed to get a dose of the insec­ti­cide, and in doing so con­tribute to the plant damage. Therefore we need a solution that helps protect our plants and trees from damage, while at the same time does not harm the environment in any way. So, how do we fight this pest?  Keep reading!

Pinyon Needle Scale- A menace to our beloved Pine trees!

 

rdyPinyon pine is a beautiful tree, offering incredible structure to a desert. One of the slowest growing trees among the conifers, the Pinyon pine can take up to a hundred years to produce a single cone. The trees yield edible pinyon nuts, which are widely eaten by the Native Americans. Annual harvest of wild pinyon nuts exceeds a million pounds! The wood, especially when burned, has a distinctive fragrance, making it a common wood to burn in chimineas.  The pinyon pine trees are also known to influence the soil in which they grow. Sadly, these amazing trees are under attack by small, black, bean shaped invasive insects known as the Pinyon needle scales. These insects can cause the leaves of Pinyon pine trees to fall off and could also kill the tree!

These tiny, sap-sucking insects kill the needles and severely weaken Pinyon pines in forests. Reduced new growth and stunted needles are common on trees suffering repeated attacks. The needle length is reduced and needles drop prematurely. Heavy infestations frequently kill small trees and predispose weakened larger trees to attack by other insects. Feeding by adult females and nymphs causes the needles to turn yellow and prematurely fall. Most defoliation occurs on older needles, producing a tufted appearance with younger needles primarily persisting on infested trees. Small trees with scales can die in a few years when untreated. However, larger trees suffer more slowly, losing one or a couple branches at a time until they die.

fhdrThis insect is most common and damaging in the United States, particularly in southern Colorado. Historic outbreaks were noted in 1957-1963 in southeast Nevada and southwest Utah, affecting several hundred thousand acres. In 2009, approximately 7% of Nevada’s pinyon forest mapped was affected by this insect. In 2010, nearly 1,161,000 acres of the approximately 9,950,000 acres of pinyon in Nevada were mapped as scale-defoliated.This represents 11.6% of Nevada’s pinyon forest!

The graveness of the issue can be better understood from the following article,

Pinyon needle scale eggs killing trees in some AZ cities

 Allison Miller

Apr 11, 2011

 PRESCOTT, AZ – Spring is providing us with warmer temperatures and beautiful spring blooms.

However, these warmer temperatures have already caused native insects, called pinyon needle scales to emerge. 

These insects can cause leaves of Pinyon pine trees to fall off and could also kill the tree.

Because of the warm temperatures, the female scales have already laid their eggs on the trees and will hatch in May. 

They can be found over thousands of acres including the Prescott area up the northwest to the Williamson Valley and are also spreading across the Payson area.

They look like noticable clusters of yellow eggs held together in loose, white, cottony webbing found in branch crotches, along the underside of branches, on the trunk, and at the base of the tree.

Bob Celaya, Forest Health Specialist says the eggs need to be spotted and treated as quickly as possible since they can kill small trees within a few years and large trees may take several years to die.

Evidently, unless proper measures are taken, the Pinyon pines may soon become extinct due to the Pinyon needle scale. Infested pine trees can be treated with chemicals and insecticides or by washing off the eggs from the surface of the trees before they get a chance to hatch. However, the efforts and costs associated with these methods, as well as the environmental safety concerns about applying toxic insecticides, make these techniques less feasible on a broad scale in natural areas.

Brown planthopper’s deadly attack on rice!

It is said that the word rice is derived from the old French word ‘ris’ which in Untitledturn has its origin Italian, Latin and Greek. Whatever be the origin of the word, it is one of the major staple for a large part of the world’s human population, especially in Asia. It is the agricultural commodity with the third-highest worldwide production, after surgarcane and maize, according to data of FAOSTAT 2012.

Being the major staple food of most of the people, the impact is harder on the population due to the shortage of the rice. One of the dangers that befall the rice food leading to its shortage is attack by pests. Brown planthoper is a major rice downloadpest which causes extensive damage and losses. Being distributed across Australia, Bangladesh, Bhutan, Burma (Myanmar), Cambodia, China, Fiji, India, Indonesia, Japan, North and South Korea, Laos, Malaysia, Nepal, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand, and Vietnam; the brown planthopper causes upto 60% yield loss. Their host plant other than rice is Leersia hexandra. They damage rice directly through feeding and also by transmitting two viruses, rice ragged stunt virus and rise grassy stunt virus.

Adults and nymph suck the phloem sap leading to hopper burn & resulting in imagesdrying of leaves. High infestation causes lodging of the crop and heavy loss in yield. Infestation is severe in high yielding varieties. Under favorable conditions they multiply very fast. Both brown planthopper(BPH) and white backed planthopper(WBPH) are known for their resistance to commonly used insecticides including the neonicotinoids. Hence crop failures due to severe pest outbreaks are very common in many rice-growing tracts of India. Temperature, relative humidity and prevailing wind direction determine the severity of incidence and spread of BPH.

In appearance the adult brown planthopper is Yellowish brown to dark brown in colour measuring 4.5 to 5.0 mm long.

  • High nitrogen levels and close plant spacing, continuous submerged, shady and humid conditions in the field tend to favor the BPH increase.
  • Extensive rice areas with irrigation facilities, multiple rice cropping are important factors for insect abundance.
  • Outbreaks of the insect pests are closely associated with insecticide misuse, especially during the early crop stages. These insecticide sprays usually directed at leaf feeding insects disrupt the natural biological control, which favor the BPH development as secondary pest.
  • The insect prefers rainfed and irrigated wetland fields to upland rice and transplanted fields to direct sown fields.

Let’s take a look at the following article highlighting the damage done by brown planthopper;

Pest attack on aman fields worries farmers

Our Correspondent, Lalmonirhat, Wednesday, October 22, 2014

Farmers in the district are worried as attack on paddy fields by brown plant hopper (BPH), locally known as current poka, poses threat to their hope for a good yield of aman this season.

Agriculture officials claim the situation is now under control while the farmers said the use of pesticides has failed to check the pest attack.

Farmers said BPH started attacking aman plants a week ago and many aman paddy fields in the district have already been attacked. They are trying to save their aman plants from being attacked by BPH, using natural methods and spraying pesticides in the fields.

Nurul Islam Bappi, a farmer of Durakuti village in Sadar upazila, said his aman plants on two bighas of land have been attacked by BPH (current poka) and it is also attacking the plants on another two bighas of land. “I have been spraying pesticides in the fields for the last three days, but to no effect,” he said.

Abdul Jalil of Jumma Para village in the upazila said BPH attacked aman plants on his three bighas of land five days ago and wreaked havoc on 50 percent plants. “As per advice of local agriculture officer, I sprayed pesticides that yielded no positive results,” he said.

Contacted, Deputy Director Safayet Hossain of the Department of Agriculture Extension in Lalmonirhat, said the situation is ‘not so alarming’. Agriculture officials are working at field level and giving advice to the farmers about use of pesticides and other methods to combat the PBH disease, he added.

Using conventional toxic pesticides will not be effective as the brown planthopper has become resilient to them. Pesticides are toxic, hazardous and pollute the environment. So a solution has to be adopted which have the traits exactly opposite to the deadly pesticides.

C Tech Corporation can offer a solution to overcome this problem. Our product Combirepel™ is an extremely low toxicity and extremely low hazard and eco-friendly rodent aversive. Combirepel™ is available in the form of solid masterbatches, liquid concentrate and in lacquer form.

Communication in termites via Semiochemicals

images (1)
Semiochemicals are small organic compounds that transmit chemical messages. They are used by insects for intra- and interspecies communication. Insects detect semiochemical directly from the air with olfactory receptors. In most insects, the receptors are located in sensilla hairs on the antennae. The term “semiochemical” has been in use since 1971. It is derived from the Greek word “semeon,” which means “sign” or “signal.” Semiochemicals were already being studied in the 1880s. Although their chemistry was not yet understood at that time, people already knew about using female insects to lure males into traps. Semiochemical research in its present form has been conducted since the 1950s, when the first pheromones were isolated and identified. From the 1950s up until today, more than 3,000 semiochemicals connected to the chemical communication of insects have been identified.

The chemical analysis of semiochemicals should consider both effect and structure. In terms of effect, semiochemicals can be classified as pheromones or allelochemicals based on how they are used and who benefits. In terms of structure, semiochemicals can be divided into twenty-four classes according to functional groups. Familiarization with the practical applications of semiochemicals is also important to the study of their chemistry.

 CHEMICAL AND PHYSICAL PROPERTIES OF SEMIOCHEMICALS

The semiochemical database Pherobase contains approximately 3,000 semiochemicals so far. Most of the molecules are small and simple, but some have structures that can be quite complicated. Semiochemicals have molecular weights ranging from 17 to 880 g/mol, but they are usually volatile. The heaviest molecules have the longest carbon chains, but there are fewer than ten semiochemicals in the database with a mass above 550 g/mol. The length of the carbon chains in semiochemicals varies from zero to forty-five carbons. The number of double bonds in semiochemical structures varies from zero to thirteen. Along with double bonds, cis-trans isomerism is a typical feature of semiochemical compounds, although positional and optical isomerism also occur. Based on effect, semiochemicals are divided into two main categories: pheromones and allelochemicals. An examination of semiochemicals must take their functions into account, since the same molecule could act as a pheromone for one insect species and as a kairomone or allomone for another. In nature, a species-specific chemical message could be generated based on an exact molar ratio, a particular form of isomerism, or isomeric mixtures, for example.

PHEROMONES

Pheromones are compounds used by insects for intraspecies communication. The term “pheromone” is derived from the Greek words “pherein” (to carry) and “horman” (toexcite/stimulate). The term was introduced in 1959 by Karlsson and Butenandt and by Karlsson and Lüscher simultaneously. The difference between pheromones and hormones is that hormones are produced in an insect’s endocrine glands. They have an effect on the insect that produces them, whereas pheromones affect other individuals instead. Based on their effect, pheromones can be divided into at least the following categories:

  • Aggregation pheromones: compounds that increase the concentration of insects at the pheromone source.
  • Alarm pheromones: compounds that stimulate insects’ escape or defense behavior.
  • Sex pheromones: compounds that help individuals of the opposite sex to find each other.
  • Trail pheromones: among social insects, compounds used by workers to mark the way to a food source, for example.
  • Marking pheromones: compounds used by insects to mark the boundaries of a territory. Dragonflies (Miettinen, A., 2006).

The effect of a semiochemical is influenced by its molecular weight. Most of the alarm pheromones, for example, have a molecular weight below 200 g/mol. Once the danger has passed, they evaporate. Trail pheromones, on the other hand, have higher molecular weights. They are not supposed to evaporate immediately.

ALLELOCHEMICALS

The allelochemicals are classified as allomones, kairomones or synomones. Allomones are a class of compounds that benefit the producer, but not the receiver. Allomones are often found in nature as part of a chemical defense, such as toxic insect secretions. Predators also use allomones to lure prey. Kairomones are a class of compounds that are advantageous for the receiver. The term “kairomone” is derived from the Greek word “kairos,” which means “opportunistic” (Nordlund et al. 1981, 18). Kairomones benefit many predators and bugs, for example, by guiding them to prey or potential host insects. Synomones (from the Greek “syn” for “with” or “together”) are compounds that are beneficial to both the receiver and the sender.

SEMIOCHEMICALS AS A POTENTIAL FOR INTEGRATED PEST MANAGEMENT

images (2)Semiochemicals (Gk. semeon, a signal) are chemicals that mediate interactions between organisms. Semiochemicals are subdivided into allelochemicals and pheromones depending on whether the interactions are interspecific or intraspecific, respectively. Within both allelochemicals and pheromones it is sometimes useful to refer to chemicals as arrestants, attractants, repellents, deterrents, stimulants or other descriptive terms. These terms can indicate what behavior is involved in the response such as a feeding stimulant or flight arrestant. Pheromones (Gk. phereum, to carry; horman, to excite or stimulate) are released by one member of a species to cause a specific interaction with another member of the same species. Pheromones may be further classified on the basis of the interaction mediated, such as alarm, aggregation or sex pheromone. It is the sex pheromones of insects that are of particular interest to agricultural integrated pest management (IPM) practitioners.

The concept of IPM is based on the recognition that no single approach to pest control offers a universal solution, and that the best crop protection can be provided by a fusion of various tactics and practices based on sound ecological principles. Pheromones are a commonly used component of many insect IPM programs (Dent, 1993 and Anonymous, 1995.) The existence of pheromones has been known for centuries, apparently originating in observations of mass bee stinging in response to a chemical released by the sting of a single bee. The two primary uses of insect pheromones are for detection and monitoring of populations and for mating disruption. These uses take advantage of sex pheromones on which a vast majority of insect pests rely to mediate reproduction.

Male annihilation is trapping carried to a seemingly logical conclusion. Place enough traps, catch enough males, and leave the females of the species without mates. This approach has been used against pink bollworms in an isolated area of Arizona with low numbers of overwintering moths. Any untrapped males simply mate more frequently. Mating disruption does not depend on traps for control, although traps are frequently used to monitor the extent of mating disruption in the population. Failure to trap males is taken as an indication that males are unable to find females which may or may not be true. Thus, trap data must always be related to actual levels of crop infestation.

Present commercial formulations of pheromones for both trap baits and mating disruption mimic the natural chemical blends of females as clearly as possible. Most insect sex pheromones are multicomponent with precise ratios of components which may be expensive to manufacture. Thus, insect sex pheromones and products containing pheromones, are commercially available primarily for insects of economic importance.

Protecting PVC from critters!

PVC has been used extensively in a wide range of construction products for over half a century. PVC’s strong, lightweight, durable and versatile characteristics make it ideal for an ample range of applications. PVC has a versatility that helps it meet the various needs of modern architecture. PVC was first used as cable insulation as a replacement for rubber during the Second World War, but has now become the superior material through its flexibility, ease of handling in installation and inherent flame retardation. PVC cables do not harden and crack over time and find use in many applications from telecommunications to electric blankets. In Europe, about 25% of all flexible PVC is used in the production of wire and cables for the electrical industries.

UK-Ant-Species-Drawn-Irresistibly-to-Electricity-2As resistant as PVC is to abrasion and corrosion, there is one thing that PVC has absolutely no resistance against-pests! Insects such as ants and termites have been long-standing enemies of PVC who damage and eventually destroy the articles. A number of insects including termites, like beetles, ants, wasps etc secrete formic acid that has the ability to dissolve the insulation of wires thereby destroying them. About 3% of the body weight of termites is made up of formic acid. Termites cause over $2 billion every year in property damage. And that’s not all wood! Termites do not eat plastic; however, the aggressive Formosan termite is known to attack plastic in search of food. Termites often chew through softer plastics. They play havoc with buried cables and sometimes bore a hole through water pipes causing service interruptions and major damage. Tunneling can lead to damage to electrical cords and cause blackouts.

Besides termites, the other species that cause major damage to PVC articles are ants. Ants going about their daily routine grow increasingly frustrated with the presence of underground optical cables and other telecommunications equipment including lawn pedestals and terminating boxes and thereby become a growing problem for telecom companies that can blame local outages on their activities. There have been a lot of incidences where outages have been directly attributed to insectarticle_img-1 activity. Material brought into the colony can overheat equipment when it blocks air vents, increased moisture from the insects can corrode or compromise sensitive electronics, and insect attempts to push PVC wiring out of the way can ruin optical cables.

Below is an article that sheds some light on the damage caused by these critters on PVC wires and cables.

‘Crazy’ Ants, New Invasive Species, Destroys Electric Wiring, Unfazed By Conventional Pesticides

Posted: 06/10/2013 

If you thought fire ants were bad, just wait until you get a load of “crazy” ants.

 Yes, crazy ants, a species of South American ant whose colony movements are so erratic that researchers could only evoke insanity when describing them.

 Also known as raspberry or tawny crazy ants, the insects have spread to Florida, Louisiana and Mississippi since first being spotted in Houston, Texas, in 2002. They “have a taste for everything from livestock to electrical equipment,” according to ABC News. They have been known to infest homes, transformers and even electronic devices such as laptops and smartphones.

 Unlike its cousin the fire ant (also called the red ant), which it has displaced in several locations, the crazy ant is highly invasive. Moving into competitive territory, crazy ants aggressively compete for other species’ resources and establish dominance. Poison bait that works on fire ants is ineffective on crazy ants because the insects won’t take it.

 “When you talk to folks who live in the invaded areas, they tell you they want their fire ants back,” Ed LeBrun, an invasive species researcher at the University of Texas, said in a UT Austin College of Natural Sciences video. “Fire ants are in many ways very polite. They live in your yard. They form mounds and stay there, and they only interact with you if you step on their mound.”

 LeBrun, co-author of a recent study on how crazy ants have displaced fire ants in Texas’ ecosystems, explained that the insects’ opportunistic nesting habits are a key factor in their biological dominance. That dominance could mean drastic changes to an ecosystem that’s adjusted to the presence of fire ants — also an invasive species — over the past 40 years.

While they are omnivorous, the ants do not actually “feast on” electrical equipment, as has been suggested. The ants damage electronics by “forming bridges between the electrical contacts” and shorting them out, LeBrun pointed out.

 Though the crazy ant threat to electronics has not been lost on the tech media, the insects are probably more a threat to your air conditioner than they are to your iPhone. As CNET notes, “You might want to think twice about leaving your laptop outside in crazy ant territory, but the ants are more likely to get into fixed equipment, house wiring and even recreational vehicles.”

rgAlthough these pests have been a source of great concern and annoyance, killing them using poisons or traps somehow seems ethically wrong, not to mention unsafe and toxic. Thus we need to find a way to protect our wires and pipes from the action of these critters, without causing any harm to them or the environment. PVC has been under attack by the action of insects for decades; however we are no closer to finding a solution for this problem than we were hundreds of years ago-until recently. C Tech Corporation provides an exceptional solution for this dilemma!

Rodent menace in agriculture!

Rodents are one of the most important vertebrate pests which directly and indirectly cause distress to the production of crops and storage of grains. Rodents cause severe damage to various crops by gnawing, spoilage, contamination and hoarding activities. The effects of rodent damage cause a huge amount of crop losses and food shortages in many parts of the world. Rodents cause millions of dollars in damages to field crops, stored grain and farm equipment each year. In addition, they are the major carrier for more than 60 diseases that are transmissible to humans, companion animals, and livestock.

In Asia alone, annual food losses due to rodents would be enough to feed 200 million people each year. Rice pre-harvest losses are estimated to be between 5-10% in most Asian countries, however, in some countries, it is expected to be significantly higher, such as Indonesia where yield loss estimates are around 19% which is the equivalent of enough grain to feed 39 million more Indonesians. However, the destruction caused by rodents on a localized level can be devastating where rodent outbreaks can wipe out entire harvests and lead to famine like conditions.

While there are different causes of rodent outbreaks, all lead to a situation whereby there are higher than normal amounts of available food which rodents has access to. Rodent outbreaks have been categorized as being cyclical or evolutional, climatic, or anthropogenic Rodent outbreaks which occur due to natural cycles include the masting or flowering of plants such as bamboo. In 2007, many poor rural communities in India, Myanmar, Bangladesh and Laos PDR were affected by such events and required food aid.

Unusual climatic events such as heavy rainfall early in the wet season or flash floods and cyclones can cause rodent outbreaks. Heavy rainfall before the beginning of the crop season, for instance, can allow the rodents’ breeding season to begin earlier due to better than usual food supply, therefore, the breeding season is extended which increases rodent numbers in the fields.

The third cause of rodent outbreaks is due to the management of cropping systems whereby there is an anthropogenic response to an extreme climatic event or market forces. The expansion of cropping areas and the intensification of cropping systems increasing the number of crop seasons per year are seen as major inducers of anthropogenic rodent outbreaks.

Let us look at some recent news articles pertaining to rodent damage in the agricultural sector.

Rodents destroy crops in district, paddy worst-hit
May 20, 2015, TOI, India

MADURAI: Rodent infestation is causing severe damage to crops across the district, specifically in paddy fields where the damage is estimated to be the highest.

Entomologists said 4.6 to 54% of paddy crops were lost due to rat infestation. The ‘bandicota bengalensis’ variety of rats is the most common troublemaker, found in crop and residential areas alike. These usually thrive in wetland areas. Another species ‘millardia meltada’ is mostly found in dry land areas.

Assistant professor of entomology at Tamil Nadu Agricultural University Usha Rani said, “You know there is a rat problem when the seeds on the planting or the rice tillers, which are grain-bearing branches formed on the base of the plant, are eaten. Rice panicle, which is a kind of flower seen on the top part of the plant, will also be missing.”

“Rodents stock about 0.5kg to 4kg of grain in their burrows in special chambers,” she added.

The rodent problem has been severe in Chellampatti and surrounding areas of the district. Crops are usually damaged when it is about 45 days old. “The maximum damage is caused to rice crops. The rodents cut the seedling in patches,” said farmer from Chellapatti area D Pandiarajan.

Rodents play havoc with paddy ryots
August 4, 2016, TOI, India

Guntur: For J Venkata Rao, a paddy grower from Ponnur mandal in the district, the last couple of years had not been great in terms of returns. While he lost his investment due to lack of adequate rainfall in 2014, rodents ate away a part of his field last year.

This year too, as Kharif season began, he is anxious as he is yet to find an effective method to eradicate the rodents.

“As soon as the transplantation of the crop begins every year, I spend sleepless nights. I grow paddy on 2 acres and I lose about six bags of the crop due to rodents,” he lamented.

Let us now look at some current methods that are used to control the rodent menace in the agricultural sector, particularly in rice fields. Throughout South and Southeast Asia studies have shown that rodents are the number one pest or the pest which causes the most damage to the rice yields. The most common technique used to control the damage caused by rodents is the use of rodenticides. However, studies show that many rodenticides have adverse effects on the health of the farmers. Rodenticides and pesticides also are responsible for the environmental degradation by polluting the soil and ground water reserves. These rodenticides also kill the non-target beneficial species like bees, earthworms etc.

So the question that arises is what should we use? This question has been answered by CTech Corporation’s Combirepel™.Combirepel™  is an extremely low toxicity and extremely low hazard and eco-friendly product of C Tech Corporation  that helps to keep rodents at bay.Combirepel™ does not kill the animal, it only repels them! In fact, it is completely safe for the target as well as non-target species. This innovative product, in masterbatch form, can be incorporated with the drip tapes, tubes, pipes, agricultural films, mulches. The product does not leach out, thus preventing soil pollution. Groundwater reserves are also not polluted. Also, the non-target beneficial species like earthworms, bees etc are not affected.

Our product in lacquer form can be coated over tree guards, fences, various PVC surfaces etc. which would ensure complete protection against these creatures. Our products provide a safe and environmentally friendly solution to avoid rodent infestation in agriculture.

The product is compliant with ROHS, ROHS2, ISO, REACH, APVMA, NEA, EU-BPR, and FIFRA exempted.

Grey squirrels: The furry terrorists

The grey squirrel is a common mammal that can delight you by its acrobatic movements and annoy by damaging trees, feeding on flower buds, bulbs, fruits and vegetables at the same time. Sciurus carolinensis, a common name grey squirrel, is a tree squirrel in the genus Sciurus. It is native to eastern North America.

These furry terrorists attack a wide range of ornamental plants, fruits and vegetables. Tulip bulbs, crocus corms, sweet corn, strawberries, apples, pears, nuts, sunflower seed heads and flower buds of camellias and magnolias are affected the most.

Grey squirrels damage trees by gnawing at the stem to get to the sweet, sap filled layers (phloem tissue) just beneath the bark with their sharp incisors as a part of their oral maintenance. This tissue is responsible for the movement of sugars around the plant known as translocation. If this gnawing extends around the stem, then the movement of sugars around the plant will come to a halt and the tree will die.

Bark stripping damage usually starts at the end of April and continues until the end of July. Trees are stripped anywhere on the main stem and branches, with vigorously growing and dominant trees generally being most affected. Damage levels vary between years and across sites within the same year. Planted or naturally regenerated trees aged between 10 and 40 years, especially sycamore, beech,  oak, sweet chestnut, pine, larch and Norway spruce, are most vulnerable to damage. Other species, especially broadleaves may also be damaged. The damages caused by bark stripping act as a major discouragement to the planting of broadleaved and coniferous trees for timber as it reduces the value of the final crop.

Up to 5% of damaged trees may die and many more will have degraded timber value through stem deformation, rot and broken tops. Oak, poplar, Scots pine and Norway spruce are particularly vulnerable to stem breakage. The fungal invasion at the damage site results in staining and rotting, reducing the value of the timber. Damage to branches in the canopy may cause dieback, affecting the timber yield.

Other damages caused by grey squirrels include digging up and feeding on bulbs and corms. Squirrels can also affect populations of small birds in woodlands by eating eggs and nestlings. Also these little critters damage lawns by burying or digging up winter food stores and gnaw on plastic, such as hosepipes and plastic netting as a part of their oral maintenance. In addition, there may be indirect competition, e.g. for food, between grey squirrels and the red squirrel. Grey squirrels also carry squirrel pox virus, an infection fatal to red squirrels.

By Linda Stewart, March 26th 2016, Belfast Telegraph, Ireland

Tollymore Forest in Co Down has been hit by an outbreak of squirrel pox five years after the virus wiped out 90% of its native red squirrels.

The disease is carried by the invasive grey squirrel, which appears to be immune to its effects, but red squirrels that contract the virus have little natural resistance and often die within 15 days of infection.

Members of the public have been urged to be on the alert for signs of infected squirrels and to report them to the authorities.

Northern Ireland Environment Agency (NIEA) Wildlife Inspector Declan Looney said: “The red squirrels in this forest had recovered well following the first outbreak five years ago but this is a further blow to them.

“Sick red squirrels will appear lethargic, approachable, with painful sores on their faces and paws. Unfortunately, there appears little natural resistance to the virus within the local population and sick animals tend to die within 10 days to two weeks. If you have squirrels entering your garden to feed at bird feeders, please either remove these or clean them daily to reduce the spread of the virus.”

  • Grey squirrels are damaging Britain’s native trees, warns Prince of Wales

By Louise Gray, April 3rd  2009, The Telegraph, UK

As patron of a new charity, The Red Squirrel Survival Trust (RSST), the Prince spoke out about the damage greys can cause. Grey squirrels strip the bark from native broadleaved trees like beech, oak, and sweet chestnut and can even kill the trees as well as eating bulbs and seeds in large quantities.

In a letter of support for the new charity, the Prince wrote: “The grey squirrels, which exist in far greater number than the reds, are causing incalculable damage to our native trees particularly the beech.”

The Prince recalls seeing reds in Sandringham, Norfolk, as a child but can now only see the species in the Royal estates in Scotland.
