昆虫雄虫射精中的附腺蛋白影响雌虫的生殖和存活。由雄性蟋蟀和Katydids提供的食物礼物，其消费也可能改变交配后的雌性行为和生理，也含有附属腺蛋白。然而，由于婚内喂养促进了精子和射精物质的转移，目前还不清楚是否是射精中的附属腺蛋白，婚礼礼物或两者都介导了这些作用。在这里，我们评估的影响，交配，婚礼礼物和附属腺蛋白质对女性生殖的礼物给蟋蟀（蟋蟀sigillatus）使用交叉实验设计。我们给不同交配经验的雌性注射雄性附腺提取物，允许一些雌性食用婚礼食物礼物，同时实验性地阻止其他雌性这样做。交配导致雌性性感受性的显著降低，这种效应可能是由雄性射精中所含的附属腺蛋白介导的。消费的婚姻食物礼物导致过早停止婚姻喂养后，女性的下一次交配，导致随之而来的减少精子转移的竞争对手男性。这是一个新的发现，证明了婚姻礼物供应对男性的健康益处也可以在以后的交配中由他们的配偶累积。无论是注射的附属腺提取物，也不影响女性产卵的婚姻喂养;没有任何影响注射的附属腺蛋白对女性生殖表明，其疗效可能取决于它们直接引入到女性生殖道。需要更多的研究来确定射精和婚姻礼物中调节女性行为和生理的特定附属腺蛋白，这可能会阐明这些性冲突背后的机械策略的演变。
Accessory gland proteins contained within male ejaculates influence female reproduction and survival in insects. Nuptial food gifts offered by male crickets and katydids, the consumption of which may also alter female behaviour and physiology after mating, also contain accessory gland proteins. However, because nuptial feeding promotes the transfer of sperm and ejaculatory substances, it is unclear whether it is accessory gland proteins in the ejaculate, nuptial gifts or both that mediate these effects. Here we evaluate the effects of mating, nuptial gifts and accessory gland proteins on female reproduction in a gift-giving cricket (Gryllodes sigillatus) using a crossed experimental design. We injected females of varying mating experience with male accessory gland extract, permitting some females to consume the nuptial food gift, while experimentally preventing others from doing so. Mating resulted in a significant decrease in female sexual receptivity, an effect likely mediated by accessory gland proteins contained in the male's ejaculate. Consumption of the nuptial food gift resulted in the premature cessation of nuptial feeding following the female's next mating, leading to a concomitant decrease in sperm transfer by a rival male. This is a novel finding, demonstrating that fitness benefits to males of nuptial gift provisioning can also accrue over later copulations by their mates. Neither injection of accessory gland extract nor nuptial feeding influenced female oviposition; the absence of any effect of the injection of accessory gland proteins on female reproduction suggests that their efficacy may depend on their direct introduction into the female reproductive tract. More research is required to identify the specific accessory gland proteins in ejaculates and nuptial gifts that modulate female behaviour and physiology, potentially illuminating the evolution of these mechanistic tactics underlying sexual conflict.
