Issues arising when interpreting results from an in vitro assay for estrogenic activity [PDF]
Concern about possible adverse effects caused by the inadvertent exposure of humans and wildlife to endocrine-active chemicals, has led some countries to develop an in vivo–in vitro screening program for endocrine effects.

Regulatory Mechanisms of Vitellogenesis in Insects
Vitellogenesis is pre-requisite to insect egg production and embryonic development after oviposition. During insect vitellogenesis, the yolk protein precursor vitellogenin (Vg) is mainly synthesized in the fat body, transported by the hemolymph through ...

Honeybee rebel workers invest less in risky foraging than normal workers [PDF]
In eusocial insect colonies, workers have individual preferences for performing particular tasks. Previous research suggests that these preferences might be associated with worker reproductive potential; however, different studies have yielded ...

We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...
