Bed Bug Deterrence, Kenneth F. Haynes, Mark H. Goodman, Michael F. Potter

Entomology Faculty Publications

A recent study in BMC Biology has determined that the immature stage of the bed bug (the nymph) signals its reproductive status to adult males using pheromones and thus avoids the trauma associated with copulation in this species. The success of this nymphal strategy of deterrence is instructive. Against the background of increasing problems with bed bugs, this research raises the question whether pheromones might be used to control them.

Socio-Environmental And Endocrine Influences On Developmental And Caste-Regulatory Gene Expression In The Eusocial Termite Reticulitermes Flavipes, Matthew R. Tarver, Xuguo Zhou, Michael E. Scharf

Entomology Faculty Publications

BACKGROUND: Strict regulation of caste differentiation, at the molecular level, is thought to be important to maintain social structure in insect societies. Previously, a number of extrinsic and intrinsic factors have been shown to influence caste composition in termite colonies. One important factor is the influence of nestmates; in particular, soldier termites are known to inhibit hormone-dependent worker-to-soldier differentiation. However, soldier influences on nestmates at the molecular level are virtually unknown. Here, to test the hypothesis that soldiers can influence nestmate gene expression, we investigated the impact of four treatments on whole-body gene expression in totipotent Reticulitermes flavipes workers: (i) …
