摘　　要：[Objective] The aim was to study on the effect of hosts on development and reproduction of mealybug （Phenacoccus solenopsis Tinsley）. [Method] Observation was conducted on developmental durations and fecundity of Phenacoccus solenopsis Tinsley fed on Gossypium spp., Nicotiana tabacum, Solanum tuberosum L and Hibiscus rosa-sinensis. [Result] There were differences among all durations, generation durations and fecundities of the mealybug adult females. Specifically, the generation durations on cotton （Gossypium spp.）, tobacco（ Nicotiana tabacum）, potato （Solanum tuberosum L） and Hibiscus rosa-sinensis were 30.2, 28.2, 37.3, and 27.7 d, and the fecundities per female were 626.0, 417.2, 552.5, and 183.2 ind., respectively. [Conclusion] The mealybug would have strong pontential in population growth when fed on cotton, tobacco and potato.[目的]研究寄主对扶桑绵粉蚧发育及繁殖的影响。[方法]观察了棉花、烟草、马铃薯、扶桑4种寄主上扶桑绵粉蚧发育历期和产仔量。[结果]取食4种寄主的扶桑绵粉蚧各虫态历期、世代历期、雌成虫繁殖能力均不同,棉花、烟草、马铃薯、扶桑上世代历期分别为30.2、28.2、37.3、27.7d,单雌总产仔量分别为626.0、417.2、552.5、183.2头。以棉花、烟草、马铃薯为食,扶桑绵粉蚧种群增殖能力增强。[结论]该研究为不同寄主植物上扶桑绵粉蚧的调查、预测预报和防治等提供参考依据。
