Mortality and repellent effects of microbial pathogens on Coptotermes formosanus (Isoptera: Rhinotermitidae). [PDF]

BMC Microbiol, 2012
Two entomopathogenic fungi, Isaria fumosorosea and Metarhizium anisopliae, and one bacterium, Bacillus thuringiensis, were tested for their ability to cause mortality of Formosan subterranean termites (FST), Coptotermes formosanus (Shiraki), after liquid exposure, and for their lack of propensity to repel FST.The fungus Isaria fumosorosea at 108 spores/

Lipid Components of Coptotermes formosanus (a Sort of Termites)

Journal of Japan Oil Chemists' Society, 1986
The fatty components of each caste of Coptotermes formosanus (worker, soldier, alate and larva of alate) were studied for determination of fatty and sterol composition. The major fatty acid components of all samples were 18 : 1, 16 : 0 and 18 : 0. But, 22.0 and 24 : 0 as fatty acids were detected in the fatty components of soldier. 17 : 0 and 17 : 1 as

Concentration-Dependent Feeding Deterrence to 20-Hydroxyecdysone for Three Subterranean Termite Species (Blattodea: Rhinotermitidae)

Insects, 2021
Effective active ingredients in toxicant bait formulations must be non-deterrent to insect feeding behavior at lethal concentrations. This study evaluated feeding deterrence for Coptotermes formosanus Shiraki, C.

Individual Behavior of Workers of the Formosan Subterranean Termite (Isoptera: Rhinotermitidae) on Consecutive Days of Tunnel Construction

Insects, 2012
This study examines the individual behavior of workers of the Formosan subterranean termite, Coptotermes formosanus Shirkai, on two consecutive days of tunnel construction. In each trial, a group of 30 termite workers was observed continuously during the

Immune-related transcriptome of Coptotermes formosanus Shiraki workers: the defense mechanism. [PDF]

PLoS One, 2013
Formosan subterranean termites, Coptotermes formosanus Shiraki, live socially in microbial-rich habitats. To understand the molecular mechanism by which termites combat pathogenic microbes, a full-length normalized cDNA library and four Suppression Subtractive Hybridization (SSH) libraries were constructed from termite workers infected with ...

Interspecific Competition and Territory Defense Mechanisms ofCoptotermes formosanusandCoptotermes gestroi(Isoptera: Rhinotermitidae) [PDF]

Environmental Entomology, 2010
Coptotermes formosanus Shiraki and C. gestroi (Wasmann) are the most widely distributed species of the genus and occur sympatrically in the subtropics. Results of two bioassays in the current study showed that C. gestroi was more aggressive than C. formosanus. In the petri-dish bioassays, C.

A Comparison of Morphology among Four Termite Species with Different Moisture Requirements

Insects, 2020
The thicknesses of the cuticle and rectal pads, and the spiracle morphology were compared for four termite species from different habitats, including one drywood termite, Cryptotermes brevis Walker, one “wetwood” termite, Cryptotermes cavifrons Banks ...

Caste‐Associated Social Context Modulates Behavioural Interactions With Insecticide‐Exposed Individuals in Nasutitermes corniger (Termitidae: Nasutitermitinae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Termites are eusocial insects that maintain cohesion and exchange information through frequent physical interactions among nestmates. This social organisation underlies the principle of horizontal insecticide transfer, which is widely exploited as a termite control strategy.

Comparison of Coptotermes formosanus and Coptotermes gestroi (Blattodea: Rhinotermitidae) Field Sites and Seasonal Foraging Activity in Hawaii

Sociobiology, 2014
Field surveys were carried out from January 2010 to June 2011 to record the environmental properties of Coptotermes formosanus Shiraki and C. gestroi (Wasmann) (Blattodea: Rhinotermitidae) field sites on the island of Oahu, Hawaii; and to document ...
