Drosophila melanogaster females restore their attractiveness after mating by removing male anti-aphrodisiac pheromones

Abstract

Male pheromones cis-vaccenyl acetate (cVA) and (Z)-7-Tricosene (7-T) mediate chemical mate-guarding in female D. melanogaster. Here, Laturney and Billeter show that females actively eject cVA from their reproductive tract post-copulation, and that cVA in concert with 7-T can reduce female attractiveness post-mating.
