Male accessory gland proteins affect differentially female sexual receptivity and remating in closely related Drosophila species.
In sexual species, mating success depends on the male's capacity to find sexual partners and on female receptivity to mating. Mating is under evolutionary constraints to prevent interspecific mating and to maximize the reproductive success of both sexes. In Drosophila melanogaster, female receptivity to mating is mainly controlled by Sex peptide (SP, i.e. Acp70A) produced by the male accessory glands with other proteins (Acps). The transfer of SP during copulation dramatically reduces female receptivity to mating and prevents remating with other males. To date, female postmating responses are well-known in D. melanogaster but have been barely investigated in closely-related species or strains exhibiting different mating systems (monoandrous versus polyandrous). Here, we describe the diversity of mating systems in two strains of D. melanogaster and the three species of the yakuba complex. Remating delay and sexual receptivity were measured in cross-experiments following SP orthologs or Acp injections within females. Interestingly, we discovered strong differences between the two strains of D. melanogaster as well as among the three species of the yakuba complex. These results suggest that reproductive behavior is under the control of complex sexual interactions between the sexes and evolves rapidly, even among closely-related species.
