主 题：bursa copulatrix cornsilk fly cryptic female choice ejaculate consumption sperm choice spermathecae
摘 要：Promiscuous mating systems provide the opportunity for females to bias fertilization toward particular ***,distinguishing between male sperm com-petition and active female sperm choice is difficult for species with internal ***,species that store and use sperm of different males in different storing struc-tures and species where females are able to expel all or part of the ejaculates after cop-ulation may be able to bias *** report a series of experiments aimed at pro-viding evidence of female sperm choice in Euxesta eluta(Hendel),a species of ulidiid fly that expels and consumes ejaculates after *** found no evidence of greater reproductive success for females mated singly,multiply with the same male,or mated multiply with different *** *** possesses two spherical spermathecae and a bursa copulatrix for sperm storage,with a ventral *** was no significant difference in storing more sperm in spermathecae 24 h after copulation than immediately after *** mated with protein-fed males had greater reproductive success than similar females mated to protein-deprived ***-fed females prevented to consume the ejaculate,retained more sperm when mated to protein-fed males than when mated to protein-deprived *** results suggest that female *** can exert control of sperm retention of higher quality males through ejaculate ejection.
