This is another subterranean termite closely related to the Formosan Termite that has managed to travel from its native Asia to many other regions of the world, including throughout the West Indies and in it was first discovered in southern Florida, and by in other areas of Florida. It also has been found on private boats arriving in Florida from islands in the Caribbean. Similar to the Formosan, the Asian Subterranean has swarming flights at dusk or at night, but usually earlier in the spring, beginning in February in Florida.

Crude seed extract of three tropical fruits belonging to the family Annonaceae, viz. Results of laboratory feeding bioassay choice and no-choice indicated that crude extract of A. Termites showed significant avoidance behavior to filter paper treated with extracts of the three Annona species investigated.
For parts of the country, the spring season marks the beginning of warmer weather, blooming flowers and termites. In Florida, where temperatures are warmer year round, termites can breed and infest homes earlier in the year, oftentimes before the official first day of spring. The warm, humid climate associated with the Sunshine State makes it the perfect home for many different species of termites. Understanding which species you are at risk for, and the signs of termite damage, is critical for homeowners looking to protect their investment.

Asian Subterranean termite colonies begin small, but may grow to over 5 million termites. Three to five years after the colony is started, winged reproductives swarmers are produced. Swarmers, or alates, do not reproduce in their original colonies.
Termites are among the world's most destructive pests, causing more than a billion dollars in damage each year in the U. Scientists in Florida have tracked the development of a new hybrid species of termite — one whose colonies grow twice as fast as the parent species. Researchers say the new "super-termite" is even more destructive than other species and may carry a significant economic cost.
The termite species known as Coptotermes formosanus and Coptotermes gestroi are the two most economically important termite species in the world, as these two species cause a greater amount of structural damages than any other termite species. These two species, which are more commonly known as Formosan subterranean termites and Asian subterranean termites respectively, have both established an invasive presence within the United States. The Formosan termite species has been inhabiting the southeast US since the s, but the Asian subterranean termite was first discovered on the southern coast of Florida during the late s, and its habitat has not yet spread beyond the state.
Kirton and Brown determined that "Haviland's subterranean termite," Coptotermes havilandi Holmgren, was a newer second name given to a termite that already had the name Coptotermes gestroi Wasmann. By proper taxonomic convention, the older name, Coptotermes gestroimust be recognized. They also proposed that Coptotermes gestroi be given the common name of "Asian subterranean termite.
Subterranean termite colonies can be as large as 1 million individuals with a foraging territory and underground galleries stretching up to meters long. How does an entomologist study something that large? A visual analogy created by termite researcher Thomas Chouvenc, Ph. Given a small, two-dimensional wooden replica of a house 30x20 cm, 2 mm thicka colony of 2, Formosan subterranean termites took only three weeks to consume it.
