The organization of social insect colonies requires sophisticated mechanisms to regulate caste composition according colony demands. In termites, the soldier is responsible for inhibition differentiation, but mechanism underlying regulation differentiation still unclear. this study, we performed transcriptome analyses identify genes expressed in workers that fluctuated presence soldiers subterr...

Toxicity and horizontal transmission of chlorantraniliprole were measured against field-collected eastern subterranean termites, Reticulitermes flavipes (Kollar). Chlorantraniliprole was highly toxic to termite workers in brief and continuous exposure assays across arange of concentrations from 5 to 100 ppm. All doses tested resulted in 100% mortality in the termites in 14 d. The effect of expo...

Lethal time to mortality responses were established for eight insecticides against workers and soldiers of the Formosan subterranean termite, Coptotermes formosanus Shiraki, and workers of Reticulitermes virginicus (Banks). There were significant differences in the tolerance ratios between workers of C. formosanus colonies to all toxicants tested except fipronil. One colony was 16 times more to...
