Reticulitermes virginicus (Banks, 1907) | |
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]
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]
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]
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.
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.
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.
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.
Alate is an adjective and noun used in entomology and botany to refer to something that has wings or winglike structures.
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.
Kalotermitidae is a family of termites, commonly known as drywood termites. Kalotermitidae includes 21 genera and 419 species. The family has a cosmopolitan circumtropical distribution, and is found in functionally arid environments.
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.
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 are destructive pests native to Asia, but have spread to other parts of the world including the United States. In Asia, this species is known as the Philippine milk termite.
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.
Reticulitermes is a termite genus in the family Rhinotermitidae. They are found in most temperate regions on Earth including much of Asia and the Middle East, Western Europe, and all of North America.
Hodotermes is a genus of African harvester termites in the Hodotermitidae. They range from Palaearctic North Africa, through the East African savannas to the karroid regions of southern Africa. As with harvester termites in general, they have serrated inner edges to their mandibles, and all castes have functional compound eyes. They forage for grass at night and during the day, and their pigmented workers are often observed outside the nest.
Incisitermes minor is a species of termite in the family Kalotermitidae known commonly as the western drywood termite. It is native to western North America, including the western United States and northern Mexico. It has been found in many other parts of the United States, all the way to the East Coast. It has been reported from Toronto. It has been introduced to Hawaii. It has been noted in China and it is not uncommon in Japan. This is an economically important pest of wooden structures, including houses. In California and Arizona alone its economic impact is estimated to be about $250 million per year.
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.
Cryptotermes brevis is a species of termite in the family Kalotermitidae, commonly known as the West Indian drywood termite or the powderpost termite. It is able to live completely inside timber structures or articles made of wood such as furniture without any outside source of water. It is frequently introduced into new locations inadvertently, and causes damage to the structural timbers of buildings and to wooden objects such as furniture.
Reticulitermes speratus, the Japanese termite, is a species of subterranean termite found in Japan, North Korea, and South Korea. It eats decayed wood. It is adapted to withstand the cold temperatures of the temperate regions it inhabits.
Amitermes floridensis, commonly known as the Florida darkwinged subterranean termite, is a species of eusocial insect in the family Termitidae. It feeds on rotting wood, reached by a network of tunnels. It is endemic to west central Florida and was first described in 1989.
Reticulitermes tibialis, the arid-land subterranean termite, is a species of termite in the family Rhinotermitidae. It is found in the United States, mostly in the western half, occurring in deserts, prairies and other dry locations.
Neotermes jouteli is a species of Neotropical dampwood termite in the family Kalotermitidae which is native to South Florida and surrounding West Indian nations. N. jouteli is the largest species of termite in Florida with soldiers reaching a maximum length of 13.35 mm and the winged alates around 16.05 mm.
Heterotermes aureus, commonly known as the desert subterranean termite, is a species of termite in the family Rhinotermitidae. It is native to the deserts of North America where the colony has an underground nest.
