Reticulitermes virginicus is a species of subterranean termite native to North America, found often in the southern United States. [1] [2] [3] It was described in 1907. [1]

Contents

Like all other termite species, R. virginicus is a eusocial species, characterized by individuals in a colony with overlapped generations cooperating in brood care and having reproductive division of labor. [4] The adults that grow wings and fly from the nest to find a mate and start a new colony are called alates, or winged reproductives. In this species they are dark brown. Alates leave the nest between early February and late May. They prefer warm and sunny afternoons after rain. [3] Like in all other termite species, all four of their wings are equal length. [5] [6] R. virginicus alates have wings about 0.3 inches (0.76 cm) long with two visible, hardened and thickened veins. [3]

Life cycle

These termites live underground, and their presence is often undetected. Winged reproductives (alates) appear above ground in the late winter or spring. When this happens inside a house, this may alert the homeowner to the fact that the termites are present. After a short flight, the insects shed their wings, and a female will search for a crevice or other suitable underground nesting site and be joined there by a male. Having mated and excavated a chamber, the female (queen) starts laying eggs. The first batch of eggs hatch into larvae which develop into workers; these enlarge the nest, search for food and carry it back to the nest. As the number of termites in the colony increases, some workers further develop into soldiers; in well-established colonies, there may be hundreds of thousands of individual insects. Alates are not produced until the colony has been established for several years. In large colonies, it is possible for workers to develop into non-winged reproductives which lay eggs to supplement the queen's effort, or which can replace her should she die. [7]

Damage

The termites tunnel underground, foraging up to 150 ft (46 m) from the nest. If they venture above ground, they create tubes to protect their passageways. They can enter buildings through joints in the mortar or cracks in the foundations. They feed on wood, and harbour symbiotic bacteria in the gut to help them digest the cellulose. They hollow out timbers, leaving a paper-thin surface intact, which may appear blistered or peeling. In the United States, Reticulitermes flavipes , Reticulitermes virginicus and Coptotermes formosanus are responsible for 80% of the damage done by termites. [7]

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.

<span class="mw-page-title-main">Blattodea</span> Order of insects that includes cockroaches and termites

Blattodea is an order of insects that contains cockroaches and termites. Formerly, termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests they evolved from within the cockroach lineage, cladistically making them cockroaches as well. The Blattodea and the mantis are now all considered part of the superorder Dictyoptera. Blattodea includes approximately 4,400 species of cockroach in almost 500 genera, and about 3,000 species of termite in around 300 genera.

<i>Reticulitermes flavipes</i> Species of insect found in North America

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.

<i>Mastotermes darwiniensis</i> Species of termite

Mastotermes darwiniensis, common names giant northern termite and Darwin termite, is a termite species found only in northern Australia. It is the most primitive extant termite species. Contrary to common belief, this species does not form mounds as the nests are subterranean and inconspicuous. Colonies will readily occupy and infest decomposing wood but primarily live in a complex subterranean network of tunnels and galleries which they use to travel to new food sites. Colonies may eventually split and form isolated satellite colonies.

<i>Nasutitermes corniger</i> Species of termite

Nasutitermes corniger is a species of arboreal termite that is endemic to the neotropics. It is very closely related to Nasutitermes ephratae. The species has been studied relatively intensively, particularly on Barro Colorado Island, Panama. These studies and others have shown that the termite interacts with many different organisms including a bat that roosts in its nest and various species of ants that cohabit with the termite.

<i>Zootermopsis angusticollis</i> Species of termite

Zootermopsis angusticollis is a species of termite (Isoptera) in the family Archotermopsidae, a group known as the dampwood termites, or the rottenwood termites. As their name suggests, the dampwood termites can only survive by living off of wood that contains high amounts of moisture. They are found along the wet environments of the Pacific coast of North America. Most are found in the states of California, Oregon, Washington, Idaho, Western Nevada and in southern British Columbia. Termites are well known to be destroyers of wood, and although the dampwood termites can cause some damage, they are not as notoriously known to cause as much damage to buildings as the drywood termites. They occasionally have been carried to other parts of the country through wood shipments, but have not been able to become established in these areas due to undesirable environmental conditions.

In Asia, this species is known as the Philippine milk termite.

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

The Hodotermitidae are a basal Old World family of termites known as the harvester termites. They are distinguished by the serrated inner edge of their mandibles, and their functional compound eyes which are present in all castes. They forage for grass at night and during daylight hours, and the pigmented workers are often observed outside the nest. Their range includes the deserts and savannas of Africa, the Middle East, and Southwest Asia. Their English name refers to their habit of collecting grass, which is not unique to the family however.

<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.
