在初步交配后，澳大利亚绵羊苍蝇Lucilia cuprina(双翅目：丽蝇科)的雌性在几天内拒绝雄性的交配尝试。几乎所有(>；98%)雌性在交配后24小时都不能接受。在交配后9天的测试中，24%的雌性拒绝产卵，45%的雌性反复给予肝脏产卵的机会。那些重新获得接受能力的交配雌性动物和处女一样容易交配。妊娠第一周期、第二周期或第三周期的雌性在提供肝脏时没有排卵，比那些产卵的雌性有更高的接受性。这些非层状材料是在重新铺设后铺设的。将1只相当于雄性附生殖腺提取物的雄性注射到处女体内，在5小时内切断它们的感受性，持续至少8天。睾丸提取液在注射5h后感受性降低，但在注射后3d无明显作用。两种提取物都增加了处女雌虫的产卵倾向。拒绝产下第二个卵块的雌性和那些没有机会产下第二个卵块的雌性在精子存储方面没有区别，而且接受第二个卵块的雌性和没有机会产下第二个卵块的雌性所占比例很高。
After an initial mating, females of the Australian sheep blowfly, Lucilia cuprina(Diptera: Calliphoridae), rejected mating attempts by males for several days. Almost all (>98%) females were unreceptive 24 h after mating. When tested 9 days after mating receptivity had returned in 24% of females denied the opportunity to oviposit and 45% of females given repeated opportunities to oviposit on liver. Those mated females that regained receptivity mated as readily as virgins. Gravid first-, second-, or third-cycle females that did not oviposit when presented with liver had a higher receptivity than those that laid. These non-layers laid after remating. Injection of 1 male equivalent of an extract of male accessory reproductive glands into virgin females switched off their receptivity within 5 h for at least 8 days. An extract of testis reduced receptivity 5 h after injection but had no detectable effect 3 days after injection. Both extracts increased the tendency of virgin females to oviposit. There was no difference in the sperm stores of females that refused to lay a second egg mass and comprised a high percentage of receptive females and those given no opportunity to lay this egg mass.
