Ejaculate Ejection by Female Fruit Flies Does Not Correlate With Mating Latency or Male Presence, Irrespective of How Ejection Is Measured.

ABSTRACT: Sexual selection operates across pre- and post-mating episodes, driven by intra-sexual competition and inter-sexual choice for mates or gametes. While these episodes can act in the same direction, this is not always the case; for example, males who are preferred as mates by females may produce sperm not preferred for fertilisation. In many species, post-mating sexual selection is measured using ejaculate ejection behaviour. However, whether different proxies for this behaviour correlate with each other, and whether the environment experienced by females post-mating influences ejaculate ejection, has received little attention until recently. Using Drosophila melanogaster, we first explore whether mating latency, a proxy for inter-sexual pre-mating preference, correlates with differen
