Water Transport byCoptotermes formosanus(Isoptera: Rhinotermitidae)
Environmental Entomology, 2014Subterranean 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.

Nootkatone Is a Repellent for Formosan Subterranean Termite (Coptotermes formosanus)
Journal of Chemical Ecology, 2001We 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.

Foraging Activities of Coptotermes formosanus in Subtropical Areas in China
Journal of Economic Entomology, 2015The foraging activities, including foraging range and seasonal fluctuation of the Formosan subterranean termite, Coptotermes formosanus Shiraki, were investigated in subtropical areas in China. Six mature C. formosanus colonies were selected for this study.

Horizontal Transfer of Spinosad inCoptotermes formosanus(Isoptera: Rhinotermitidae)
Journal of Economic Entomology, 2016Slow-acting and nonrepellent termiticides are possible candidates for nestmate to nestmate transfer called horizontal transfer. For the horizontal transfer study of spinosad, Coptotermes formosanus Shiraki was released in sand and soil at 1, 25, and 50 ppm Entrust(®) for 1 h and then mixed with healthy untreated termites for 21 d at the ratio of 1:1 ...

Sporulation of Metarhizium anisopliae and Beauveria bassiana on Coptotermes formosanus and in vitro
Journal of Invertebrate Pathology, 2002The 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, 2008Termites, 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, 1982Abstract 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).
2021Abstract 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 ...

The complete mitogenome of the Formosan termite, Coptotermes formosanus Shiraki
Insectes Sociaux, 2011The Formosan termite Coptotermes formosanus Shiraki is a well-known invasive pest that causes severe damage to wooden structures in many parts of the world. Although several studies examined its phylogeographic patterns using a few mitochondrial genes, the phylogenetic relationships among C.
