Abstract

Coptotermes gestroi originates in Southeast Asia and is recognized as an invasive species. It has spread across the world from its origin, to Territories such as Taiwan, Mauritius, R??eunion Island, and across the Pacific ocean to parts of Polynesia, Hawaii, Marquesas Island, Micronesia, Fiji, Mexico, Florida, Caribbean Islands, and is now spreading along the south Atlantic coast of Brazil. The invasive nature of this termite has been well reviewed by Evan et al. Reports of the species sighting in Italy is also notable, although the infestation was reported in a yacht in Sicily. Similar reports of the species infesting sea vessels provide insights how the species has moved across the world. In addition to its invasive nature, the species is known for its propensity to establish itself in urban areas, causing damage to wood and wooden structures used by man. The species also consumes all forms of wood commonly used in structures including household items in addition to selective species of live trees. Reports of damage to fabrics as well as home fixtures and upholstery materials have also been noted. The species also shows a unique subterranean method of entering structures using sub-floor cracks in concrete and brickwork. It is also known to make its way into a structure through expansion joints as well as electrical conduits and regular service penetrations are common. Damage resulting from a C. gestroi infestation can become severe in a relatively short time, especially when a structure is invaded by a large, mature colony. Dispersal flights, foraging tubes, or damage are usually the first indications of an infestation. Advanced stages of infestation are indicated by the incorporation of nest material (carton) in hollowed wood or existing structural voids. All of these characteristics make C.gestroi a species of significant economic importance around the world.
