Sight of parasitoid wasps accelerates sexual behavior and upregulates a micropeptide gene in Drosophila
Abstract
Parasitoids exploit host bodies for reproduction, selecting for host defences. A new host defence is reported, in which adult Drosophila accelerate mating behaviour at the sight of certain parasitoid wasps, mediated by the upregulation of a nervous system gene that encodes a 41-amino acid micropeptide.
