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 insect dopaminergic system serves an important function in the regulation of ontogenesis and early development, contributing to the evolutionary processes that limit the ecological niche of Drosophila sechellia.

A functional genetics approach reveals a novel role for odorant binding proteins in post-mating processes, with complex mechanisms of evolutionary change across closely related insect species.

Evolutionary changes in cuticular hydrocarbons, a lipid layer on the insect epicuticle, underlie the evolution of desiccation resistance in Drosophila species.

The conserved biochemical activity of the duplicate Bab transcription factors were integrated into the regulatory hierarchy of an evolving gene regulatory network by binding site gains in a target gene's cis-regulatory region.

Drosophila's second nose, the maxillary palp, is involved in short- and long-range attraction.

Differences in the usage of DNA repair pathways may give rise to the unique patterns of Y-linked mutations that, together with natural selection, shape rapid Y chromosome evolution.

A 'hotspot' position in an olfactory receptor protein family underlies changes in odor tuning in different receptors at different times during evolution.

The short lifetime of orphan genes is a major factor explaining the stability of gene number in Drosophila.

An analysis of within-host bacterial proliferation reveals that minor "stochastic" variation in the ability of the innate immune response to control bacterial growth early on can result in either survival or death of the host.
