Sex-peptide is the molecular basis of the sperm effect in Drosophila melanogaster.

Proceedings of the National Academy of Sciences of the United States of America - 19 Aug 2003

Liu Huanfa, Kubli Eric

Abstract excerpt

Mating elicits two major changes in the reproductive behavior of many insect females. The egg-laying rate increases and the readiness to accept males (receptivity) is reduced. These postmating responses last approximately 1 week in Drosophila melanogaster. Males that do not transfer sperm but transfer seminal fluid during mating induce a short-term response of 1 day. The long-term response of 1 week requires the...
