Ejaculate feeding and female fitness in the sexually dimorphic fly Prochyliza xanthostoma (Diptera: Piophilidae)
Article Abstract:
The effects of ejaculate ingestion on female fitness in the piophilid carrion fly, Prochyliza xanthostoma, are investigated by manipulating females' opportunity to ingest the ejaculate under two background food levels (fed as libitum versus starved). The benign effects of ejaculate feeding on female fitness and the lack of evidence of sexual conflict are consistent with the low female remating rate in this species, suggesting that sexual conflicts have played a role in the evolution of these traits.

Temporal manipulation of ejaculate components by newly fertilized Drosophila melanogaster females
Article Abstract:
Newly fertilized Drosophila melanogaster females still elicit vigorous courtship behavior from males immediately after mating but these females are not receptive to copulation. Once these females begin laying eggs, they fail to elicit courtship behavior. This indicate that neither ovipositor extrusion or male pheromones left on the female cuticle after mating discourages the other males from courting the newly fertilized female.

Evidence that 3-keto petromyzonol sulphate specifically attracts ovulating female sea lamprey, Petromyzon marinus
Article Abstract:
A study on the hypothesis that 3-keto petromyzonol sulphate (3kPZS) constitutes a major component of a male sea lamprey sex pheromone was conducted. The study revealed that male sea lampreys release 3kPZS after spermination and that 3kPZS specifically influences the behaviour of ovulating the females.
