Evolutionary reconstruction of the ecdysis pathway shows that its major elements are present in the majority of metazoans, providing evidence that they originated much earlier than currently assumed.

The response of the peptidergic neurons that control a stereotyped behavior depends on the actions of a triggering neuropeptide, downstream neuropeptides and GABA inhibitory influences.

Prothoracicotropic hormone and ecdysone belonging to the insect PG axis modulate virgin female sexual receptivity.

A hormone released after mating acts directly on adult intestinal progenitors and differentiated epithelial cells in Drosophila to change their homeostatic setpoint and maximise fecundity.

Secretory cells in the fruit fly reproductive tract produce secretions that control ovulation through a conserved mechanism that could provide insights into ovarian cancer.

4-Vinylanisole acts as maturation-accelerating pheromone to synchronize oocyte maturation of female adults in locusts.

Molecular and biochemical methods provide the first evidence of toxicity of imidacloprid causing developmental retardation in honeybee larvae, highlighting the potential risks of prolonged exposure to insecticides during animal development.

Two functionally antagonizing groups of hormones directly regulate starvation-induced increase in locomotion via a common neural target in fruit flies.
