Sex peptide is required for the efficient release of stored sperm in mated Drosophila females.

Genetics - 1 Oct 2010

Avila Frank W, Ravi Ram K, Bloch Qazi Margaret C, Wolfner Mariana F

Abstract excerpt

The Drosophila seminal fluid protein (SFP) sex peptide (SP) elicits numerous post-mating responses, including increased egg laying and decreased sexual receptivity, in the mated female. Unlike other SFPs, which are detectable in mated females for only a few hours post mating, SP is maintained-and its effects are sustained-for several days. The persistence of SP in the mated female's reproductive tract is thought...
