A moth can detect plant volatiles using an odorant receptor expressing in its ovipositor, and this odorant receptor has a much higher expression level in the ovipositor than antennae.

After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.

The first evidence is presented of a compound released by mated females that directly counteracts the effects of a seminal anti-aphrodisiac, but has no attractant properties in itself.

Triacylglycerides found in the males of 11 species of Drosophila form a largely overlooked, novel, sex-specific class of pheromones that act to suppress courtship behaviour.

The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.
