Abstract
Females increase aggression for mating oppor-tunities and for acquiring reproductive resources.Although the close relationship between female aggression and mat-ing status is widely appreciated,whether and how female aggression is regulated by mating-related cues remains poorly understood.Here we report an interesting observa-tion that Drosophila virgin females initiate high-frequency attacks toward mated females.We identify 11-cis-vacce-nyl acetate(cVA),a male-derived pheromone transferred to females during mating,which promotes virgin female aggression.We subsequently reveal a cVA-responsive neural circuit consisting of four orders of neurons,including Or67d,DA1,aSP-g,and pC1 neurons,that mediate cVA-induced virgin female aggression.We also determine that aSP-g neurons release acetylcholine(ACh)to excite pC1 neurons via the nicotinic ACh receptor nAChRα7.Together,beyond revealing cVA as a mating-related inducer of virgin female aggression,our results identify a neural circuit linking the chemosensory perception of mating-related cues to aggres-sive behavior in Drosophila females.
