To clarify the effects of sublethal concentration of insecticide on the growth, development and reproduction of Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), the sublethal and transgenerational effects of the LC₃₀ of six insecticides on adults and progeny (F₁ and F₂ generations) were studied using age-stage, two-sex life tables. Exposure to six insecticides had significant negative impacts on the life-history traits of B. dorsalis and led to reduced adult longevity and fecundity in F₀, a longer larval stage duration in F₁, and reduced fertility and survival. The intrinsic rate of increase (r), finite rate of increase (λ), and net reproductive rate (R₀) were reduced in F₁, with the greatest reduction observed in the chlorpyrifos treatment. In the F₂ generation, the adverse effects were weakened, only the cyantraniliprole treatment had lower values than the control, and the fecundity of other treatments returned to normal. Obvious “hormesis” phenomena were not observed in any of the generations. Based on the population hazard index, chlorpyrifos had the best control effect in the early stage, and cyantraniliprole had the best control effect in the long term. These results indicate that the LC₃₀ of the six insecticides exert different transgenerational effects on the B. dorsalis population.

为了阐明杀虫剂的亚致死浓度对桔小实蝇（Hendel）（双翅目：蝇科）的生长，发育和繁殖的影响，以及六种杀虫剂的LC ₃₀对成年和子代的致死和传代作用（F ₁和F _2）几岁）使用两阶段性寿命表进行了研究。暴露于六种杀虫剂会对桔小实蝇的生活史特征产生重大不利影响，并导致F _0的成年寿命和繁殖力降低，F _1的幼虫期持续时间延长，生育力和存活率降低。固有增长率（r），有限增长率（F _1中的λ）和净生殖率（R ₀）降低，毒死rif处理中观察到的降低最大。在F ₂代中，不良反应减弱了，只有氰基氰基丙烯腈处理的值比对照组低，而其他处理的繁殖力又恢复了正常。在任何一代中都没有观察到明显的“兴奋剂”现象。从种群危害指数来看，毒死rif在早期的防治效果最好，而氰基苯丙胺类在长期的防治效果最好。这些结果表明，六种杀虫剂的LC ₃₀对背叶双歧杆菌种群具有不同的跨代效应。
