摘　　要：为研究交配对扶桑绵粉蚧雌虫发育及产卵的影响,比较了不同交配条件下扶桑绵粉蚧雌虫的寿命、产卵习性和产卵量。结果表明,交配对扶桑绵粉蚧雌虫的卵巢发育和产卵有促进作用。与延迟交配的扶桑绵粉蚧相比,正常交配的扶桑绵粉蚧雌虫卵巢内总产卵量、孕卵期、产卵期和首次产卵量均显著提高;而未经交配的雌虫体内的卵细胞不能受精。延迟交配的雌虫可以通过对营养的重新分配延长自身寿命,一旦发生交配,体内生理发生重导向可再次产卵,产卵量显著低于正常交配雌虫。To study the effects of mating status on development and oviposition in female mealybugs, Phenacoccus so-lenopsis.We compared the longevity, ovarian development and number of eggs laid in Phenacoccus solenopsis under different mating status.The results showed that in Phenacoccus solenopsis, mating stimulated ovarian development and oviposition.Mated Phenacoccus solenopsis females had higher total number of eggs laid, duration of gestation, duration of reproduction and number of eggs laid in the first clutch compared to delay-mated females.When grown into oviposi-tion period, unmated females could not develop into the embryonic phase and laid few eggs.Delay-mated females could make a trade-off between maintenance and reproduction by a nutritional rearrangement, which indicated that females would resorb the resources from eggs for a longer survival when they couldn＆#39;t get mated.Once mated, females would lay eggs, and their physiological state got reset, but the number of eggs laid was lower than mated females.
