Coptotermes

By |2016-12-17T19:45:47+00:00December 17th, 2016|

The genus Coptotermes (termite) is characterized by the presence of a pear-shaped head, narrow at front with a pointed labrum in the soldier caste (Pearce et al., 1993). Mandibles are slender, sharply pointed and slightly incurved without marginal teeth. Most distinctive in the soldier caste is the large fontanelle (opening) at the front of the […]

termite alates

By |2016-12-17T19:44:06+00:00December 17th, 2016|

These are often called primary reproductives. At certain times of the year, a mature colony will produce these in large numbers and they will swarm when conditions are right. This generally coincides with rainfall. Formosan termites tend to swarm at dusk or early evening. These are often called “swarmers” and can be seen around street […]

termite larvae

By |2016-12-17T19:43:30+00:00December 17th, 2016|

Larvae are the immature stages and resemble very small workers. Larvae grow through a number of molts to become workers, nymphs or soldiers. They are cared for by workers until they have reached the worker stage. Nymphs are immature individuals with wing buds. Then through a number of molts, they eventually become alates (flying termites). […]

termite soldier

By |2016-12-17T19:42:59+00:00December 17th, 2016|

The main function of the soldier termite is to defend the colony. Soldiers have an enlarged, hard head with two large jaws. When openings occur in the galleries, they quickly position themselves at the opening with their jaws open and pointing outwards from the hole. When alarmed, soldiers termites will bang their heads against the […]

termite worker

By |2016-12-17T19:42:37+00:00December 17th, 2016|

The termite worker caste is by far the largest group within the colony. These creamy white, soft-bodied insects are the ones that damage wood and other cellulose containing materials as this is their primary food. Workers are blind and wingless. They are responsible for nearly all the work within the colony. These activities include caring […]

termite queen

By |2016-12-17T19:41:44+00:00December 17th, 2016|

The primary role of the queen is reproduction. Once mated with the king, the queen begins her life-long role as egg producer. The queen can live for ten or more years and can produce over 1,000 eggs per day. Her stomach expands as her egg-laying capacity increases. She normally lives within a chamber where she […]
