Coptotermes acinaciformis: A major cause of wood damage in Australia

Be it homeowners, hotel owners, library owners or theatre owners, they have one enemy in common and they are termites!! And when they are as dangerous as Coptotermes acinaciformis, there is a great reason to worry about. Let’s get to know more about these species.

Coptotermes acinaciformis can be found in widespread areas throughout downloadAustralia. They are predominantly found in urban areas and where eucalypts are abundant. They are the second most destructive termite in Australia and cause the greatest amount of structural damage to buildings, timber structures, trees and electrical wiring.

These species are most commonly found in the base of trees and stumps and in built in patios, under concrete slabs and buried timber, wherever there is moisture and a secure hiding place to form a nest. They love it between garden sheds and the fence when timber is left there. One of the most destructive elements of this species is that it can form ancillary nests, away from the main colony, particularly in wall cavities.

download (1)Coptotermes acinaciformis are subterranean termite species 5.0-6.6 mm in length, and they have sabre like the mandibles with no obvious teeth. The labrum is not grooved and the head is pear-shaped and rounded laterally. Fontanelle is obvious on the anterior part of the head. Tarsi (skeleton) have 4 segments and abdominal cerci have 2 segments. It pronotum(dorsal) is flat and it does not have any anterior lobe.

imagesThe life cycle of these species is a gradual process. Queen lays eggs singly. A nymph after hatching passes through 4-7 moults before becoming a mature worker, soldier or winged reproductive. Nymphs resemble the adults or mature castes. Nymphal stage lasts approximately 2-3 months, depending of food and climatic conditions. No pupal stage exists. Soldiers and workers live for 1-2 years.

There are 4 different castes of adults:

  1. Queen and King:

The queen and king are the original winged reproductives (dealates). When a new colony is formed the pair must feed and care for the young until there are sufficient soldiers and workers to take over the duties of the colony.

  1. Worker:

This is the most abundant caste in the colony, performing all the tasks except defence and reproduction. It is this caste that does damage to timber. These are the males and females whose sexual organs and characteristics have not developed. They are wingless, blind and sterile. They also have a thin cuticlewhich makes them susceptible to desiccation. They are the kind of species which will leave the security of underground tunnels and shelter tubes only when humidity is high or in the search for new food sources.

  1. Soldier:

This is the most distinctive and the easiest caste from which to identify a species. The role of this caste is to defend the colony. These consist of males and females whose sexual organs and characteristics have not developed. Li ke the workers caste, they are susceptible to dessication and seldom leave the colony or shelter ubes. The fontanelle is used to discharge a secretion associated with defence, since it is a repellent to ants and other enemies of termites.

  1. Reproductive:

They are the future kings and queens. Having compound eyes, they are darker in colour and have a more dense cuticle than workers and soldiers. They are often large. When fully winged(alates) a colonising flight will occur when humidity and temperature conditions outside approximate the conditions inside the colony, normally in summer months.

These mostly nests in trees, stumps, poles or filled-in verandahs where timber has been buried. Soil contact is desirable, but not essential depending on an assured water supply and security in its habitat.

Workers feed on wood, wood products, leaves, bark and grass. The cellulose of wood is digested by intestinal protozoa. The other castes are fed by the workers from oral and anal excretions. Protein is also required in the diet, which is usually supplied by fungi that decay wood and vegetation.

Coptotermes “acinaciformis” gets its name from the fact that the soldiers excrete formic acid from their mouths when they are threatened. This poses a problem for wiring in buildings infested with this species. These are most widely distributed timber pest in Australia, accounting for more than 70% of the serious damage to buildings in New South Wales. A single colony may consist of more than one million termites.

Hence to help alleviate or else completely eradicate the infestation we C Tech Corporation provide you with the best effective solution Combirepel™.Combirepel™ is an anti-insect aversive developed on the grounds of green chemistry and technology.

Our product works on the mechanism of repellency. It temporarily inhibits the mating cycle of the insects. The product impairs the ability of the insects to reproduce, that is the insects will not lay eggs or the laid eggs will be infertile. The product causes feeding disruption in an insect by triggering an unpleasant reaction within the insect which might try to feed on the application. The product temporarily blocks the reproduction system of the insects by hindering the release of the vital hormones for growth.

Combirepel™ is thermally stable and does not degrade on exposure to heat and sunlight. It does not kill or harm the insect but repels them. It does not volatilize and does not degrade the soil. It is RoHS, RoHS2, ISO, REACH, APVMA, NEA compliant and FIFRA exempted.

Combirepel™ is an eco-friendly product which acts as an aversive to repel the pesky insects like roaches. Combirepel™ do not kill the targeted as well as non-targeted species but just repel them causing no harm no to human and environment.

Combirepel™ is available in the form of masterbatch, liquid concentrate, and lacquer. Our Combirepel™ masterbatch can be used in polymer base applications like wires, cables, irrigation pipes, polymeric vessels, and other various applications.

Combirepel™ liquid concentrate can be mixed in the paints to cover the areas like cracks and crevices of walls and hidden places where the roaches tend to survive.

Combirepel™ lacquer is the topical coating to cover the places like bathrooms, cupboards, steam tunnels, etc.

Hence we provide you with the best effective solution.
