Elimination and reinvasion studies with Coptotermes formosanus (Isoptera: Rhinotermitidae) in Louisiana.

Journal of economic entomology, 2005
Three Formosan subterranean termite, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae), colonies located inside the 12.75-ha Louis Armstrong Park, New Orleans, were selected for elimination by using the chitin synthesis inhibitor hexaflumuron.

The nature of soil pernicious to Coptotermes formosanus

Journal of Invertebrate Pathology, 1982
Abstract The Formosan subterranean termites, Coptotermes formosanus , were incubated in soils collected from various locations on the island of Hawaii. More than 70% of the termites died within 2 weeks in seven of nine soil samples collected from Kamuela. In control soil termites remained alive after 4 weeks.

Molting in workers of the Formosan subterranean termite Coptotermes formosanus

Journal of Insect Physiology, 2008
The Formosan subterranean termite, Coptotermes formosanus, with its huge colonies, is a major urban pest in several southern states and Hawaii as well as in South Asia. Because of their cryptic nature (underground habitat) and very long life cycle, not much is known about molting in termite workers. In C.

Nootkatone Is a Repellent for Formosan Subterranean Termite (Coptotermes formosanus)

Journal of Chemical Ecology, 2001
We examined the behavior of Formosan subterranean termites toward one of the components of vetiver grass oil, the roots of which manufacture insect repellents. We found nootkatone, a sesquiterpene ketone, isolated from vetiver oil is a strong repellent and toxicant to Formosan subterranean termites.

Water Transport byCoptotermes formosanus(Isoptera: Rhinotermitidae)

Environmental Entomology, 2014
Subterranean termites are extremely vulnerable to desiccation, and high moisture makes their habitat and food favorable for survival and colony growth. Although there is a general perception that termites can manipulate moisture, documentation is surprisingly scanty with regard to how termites transport water and the factors that impact it.

Sporulation of Metarhizium anisopliae and Beauveria bassiana on Coptotermes formosanus and in vitro

Journal of Invertebrate Pathology, 2002
The sporulation of 22 total isolates of Metarhizium anisopliae and Beauveria bassiana was quantified on cadavers of the Formosan subterranean termite, Coptotermes formosanus. Conidial production increased significantly over 11 days post-death. Effects of isolates of M. anisopliae and B. bassiana on in vivo sporulation were significant.

Defense mechanism of the termite, Coptotermes formosanus Shiraki, to entomopathogenic fungi

Journal of Invertebrate Pathology, 2008
Termites, Coptotermes formosanus Shiraki, reared individually, were highly susceptible to entomopathogenic fungi, Paecilomyces fumosoroseus and Beauveria brongniartii and Metarhizium anisopliae, while termites reared in groups were highly resistant. Quantitative assays with an epifluoresent microscope revealed a significant difference in the number of ...

Pathogenicity of six strains of entomogenous fungi to Coptotermes formosanus

Journal of Invertebrate Pathology, 1982
Abstract One strain (2A3) of Beauveria bassiana, two strains (N-22; T-27) of Beauveria sp., and three strains (Tonga; 10B; MM-773) of Metarhizium anisopliae were tested for their pathogenicity to workers from a colony of Coptotermes formosanus. A microsyringe method for estimating and applying the inoculum was employed in these tests. On the basis of

Coptotermes formosanus (Formosan subterranean termite).

2021
Abstract C. formosanus is often transported by boats and shipping containers to port cities before being carried further inland via landscape materials such as railroad ties (railway sleepers). This may explain the current C. formosanus distribution in the USA with coastal areas more densely infested than inland areas (Hochmair and ...
