Journal ArticleDOI
Cost of mating in Drosophila melanogaster females is mediated by male accessory gland products
TL;DR: It is demonstrated here that seminal fluid products from the main cells of the male accessory gland are responsible for the cost of mating in females, and that increasing exposure to these products increases female death rate.
Journal ArticleDOI
Probing the function of Drosophila melanogaster accessory glands by directed cell ablation
TL;DR: The generation and phenotype of flies that lack functional accessory-gland main cells as a consequence of genetically directed delivery of diphtheria toxin subunit A to those cells are reported.
Journal ArticleDOI
The Drosophila melanogaster seminal fluid protein Acp62F is a protease inhibitor that is toxic upon ectopic expression.

TL;DR: It is proposed that Acp62F's protease inhibitor activity exerts positive protective functions in the mated female's reproductive tract but that entry of a small amount of this protein into the female's hemolymph could contribute to the cost of mating.
Journal ArticleDOI
Mating and hormonal triggers regulate accessory gland gene expression in male Drosophila
TL;DR: By exposing males to females whose ovipositors had been sealed shut, it is shown that resynthesis of accessory gland proteins occurs only when seminal fluid is transferred to females, and applying juvenile hormone or 20-hydroxyecdysone topically to the cuticle of male flies showed that these hormones can act in vivo to stimulate the synthesis of accessory glands proteins to levels similar to those observed after mating.
