Coptotermes gestroi, commonly known as the Asian subterranean termite is a small species of termite that lives underground. Both this species and the Formosan subterranean termite (Coptotermes formosanus) are destructive pests native to Asia, but have spread to other parts of the world including the United States. [1] In Asia, this species is known as the Philippine milk termite. [2]

Contents

The termite species Coptotermes havilandi was determined by Kirton and Brown in 2003 to be identical to Coptotermes gestroi, so following the principle of priority, the older name is now used. [3]

Distribution

C. gestroi is endemic to Southeast Asia, but has spread to many other parts of the world over the course of the last century. It reached the Marquesas Islands in 1932, Mauritius in 1936, and Réunion in 1957. It reached Barbados in 1937 and spread to many islands in the West Indies. It also occurs in southern Mexico. [1] It was discovered in Fiji in 2009. [4]

It was found in a single house in Hawaii in 1963 and was next detected there in 1999 and again in 2000, on the island of Oahu. The species is the subject of a research project at the University of Hawaii. [2]

In 1996, a colony was found to be infesting a church and store in Miami, Florida, [5] and another infestation was discovered in 1999 in Key West. Further discoveries were made in 2002 and 2006 and the species appears to have become established in Broward and Dade Counties. It has also been found on some boats moored off the coast of Florida and it is thought that the termite may have arrived in Florida via this means, with sexually mature adults reaching the mainland after nuptial flights. In the West Indies, it has become established in some natural woodland habitats, but in Florida, it seems to be restricted to manmade structures, trees growing close to them, and boats. In the mainland United States, this species is likely to remain restricted to southern Florida because it is a tropical species and can only flourish with sufficient warmth. [1]

Chouvenc & Helmick 2015 find that C. gestroi readily hybridizes with another invasive termite in Florida, C. formosanus . [6]

Description

The body of the worker termite is small, white, and translucent as are the limbs. The soldier is larger and also white, but the ovoid head, the forward-pointing mandibles, the prothorax, and the front segments of the abdomen are dark brown. Two small pale spots are on the head adjacent to the antennae. On the forehead is an opening called a fontanelle which can extrude a white defensive secretion. In appearance, C. gestroi is very similar to C. formosanus, but they can be differentiated under the microscope, with the number of hairs on the head of the soldier differing in the two species. [1]

Castes

Life history

Like other species of termites, an Asian subterranean termite colony contains three primary castes: the workers, soldiers, and reproductives. The workers are responsible for feeding the colony and caring for the young, and the soldiers are responsible for its defence. The king mates with the queen, whose chief function over a life of many years is the continuous laying of eggs. Her abdomen increases in size enormously in comparison to that of the king. [7] The workers feed her, as she is unable to feed herself. In a mature colony, some eggs develop into winged reproductives, known as alates. They emerge above ground and form a swarm containing many thousands of individuals. This usually happens in the evening or at night in the spring. When a swarm is found inside a building, this may be the first sign to the owners of the presence of termites in the structure. On returning to the ground, the alates shed their wings. They are unlikely to find a suitable place to start a colony inside a building, but in the open, each female looks for an appropriate site with damp soil and moist timber. In a suitable crevice, a female and a male form a nursery chamber and 15 to 30 eggs are laid. These are reared by the king and queen and a second batch of eggs is laid a few weeks later. Workers from the first batch care for these. It may take several years for the colony to build up to sufficient numbers for winged reproductives to be formed. [8]

In a research study in Thailand, the foraging population of an average colony was 1.13 to 2.75 million individuals. [9]

Damage

These termites are voracious feeders and consume wood, cardboard, and paper and sometimes even fabric. [10] They feed on all sorts of cellulose-containing materials and drill holes in such materials as rubber, plastic, and styrofoam in their search for food. They also attack living trees by consuming the heartwood which weakens the trees and can bring them down in a storm. They live underground and enter buildings through cracks, expansion joints, and utility conduits. They sometimes form foraging tubes along the surface of the ground and the outside surfaces of structures. They eat structural timbers from the inside outwards, leaving a thin film of surface wood which may display a blistered appearance. [8] In Singapore and Malaysia, this species is responsible for 80% to 90% of the damage caused to manmade structures by insects and it is the commonest species of termite found in built-up areas.

Termites are a group of detritophagous eusocial insects which consume a wide variety of decaying plant material, generally in the form of wood, leaf litter, and soil humus. They are distinguished by their moniliform antennae and the soft-bodied and typically unpigmented worker caste for which they have been commonly termed "white ants"; however, they are not ants, to which they are distantly related. About 2,972 extant species are currently described, 2,105 of which are members of the family Termitidae.

Reticulitermes flavipes, the eastern subterranean termite, is the most common termite found in North America. These termites are the most economically important wood destroying insects in the United States and are classified as pests. They feed on cellulose material such as the structural wood in buildings, wooden fixtures, paper, books, and cotton. A mature colony can range from 20,000 workers to as high as 5 million workers and the primary queen of the colony lays 5,000 to 10,000 eggs per year to add to this total.

<span class="mw-page-title-main">Rhinotermitidae</span> Family of termites

Rhinotermitidae is a family of wood-soil interface feeding termites commonly known as the Subterranean termites. Many members of this family are known pests that can cause extensive damage to buildings or other wooden structures. Most species establish colonies in wood before migrating to the ground to create diffuse nests connecting to multiple pieces of wood, with some taxa such as Coptotermitinae creating mounds or centralized carton nests within wood. All members forage via shelter tubes through the soil to sources of food. In addition, Rhinotermitidae are known for having a higher level of social complexity as compared to other termites. Communication takes place through chemical activity, more specifically through traces of cuticular hydrocarbon (CHC), or semiochemicals, acting as pheromones to send signals to the king and queen of the nest. About 345 species are recognized, among these are severe pests such as Coptotermes formosanus, Coptotermes gestroi, and Reticulitermes flavipes.

<i>Coptotermes</i> Genus of termites

Coptotermes is a genus of termites in the family Rhinotermitidae. Many of the roughly 71 species are economically destructive pests. The genus is thought to have originated in Southeast Asia.

Coptotermes frenchi, the Australian subterranean termite, is a species of termite in the family Rhinotermitidae. Termites are social insects and C. frenchi usually builds its communal nest in the root crown of a tree. From this, a network of galleries extends through the nearby soil, enabling the workers to forage in the surrounding area without emerging on the surface of the ground.

<i>Coptotermes acinaciformis</i> Species of termite

Coptotermes acinaciformis is a species of subterranean termite in the family Rhinotermitidae native to Australia. Termites are social insects and build a communal nest. In the case of C. acinaciformis, this is either in the root crown of a tree or underground. From this, a network of galleries extends through the nearby soil, enabling the workers to forage in the surrounding area without emerging on the surface of the ground. This termite can cause substantial damage to trees and the wooden parts of buildings.

It is native to tropical India, Pakistan and Sri Lanka but has extended its range into the subtropics and warm temperate areas of the Himalayan foothills to altitudes of about 2,000 m (6,600 ft). It causes damage to timber in buildings and is one of the most destructive termites in urban and agricultural areas in the world. Soldiers are about 4.1-4.9mm long.
