Abstract：
Spodoptera frugiperda (J. E. Smith), commonly known as the fall armyworm (FAW), causes significant damage to many different crop species. In this study, age-stage, two-sex life table analysis was used to investigate the effects of sublethal concentrations of emamectin benzoate and chlorantraniliprole on FAW development and reproduction. In the F0 generation, exposure to emamectin benzoate and chlorantraniliprole significantly impacted the duration of FAW, thus prolonging the development duration of each instar, but not the prepupal stage. Furthermore, the weight of FAW pupae was significantly reduced by emamectin benzoate at LC25 and chlorantraniliprole at LC25 in the F0 generation. With respect to fecundity, emamectin benzoate and chlorantraniliprole significantly reduced fecundity in the F0 generation. In the F1 generation, emamectin benzoate at LC10 had no significant effect on the preadult or adult stages, whereas LC25 significantly shortened the preadult period. The preadult and adult stages of FAW exposed to chlorantraniliprole at LC10 and LC25 were significantly prolonged. Furthermore, emamectin benzoate had no significant effect on the pupal weight of the F1 generation. Chlorantraniliprole had no significant effect at LC10, but significant reduced pupal weight occurred at LC25 in the F1 generation. With respect to fecundity, emamectin benzoate significantly reduced fecundity in the F1 generation. Interestingly, chlorantraniliprole significantly increased fecundity in the F1 generation, which could promote population growth and pest resurgence. These findings have important implications for the integrated pest management of FAW and provide a reference for the more effective control of FAW.
摘要：
节食夜蛾（J.E.Smith)，俗称秋季粘虫(FAW)，对许多不同的作物物种造成重大损害。在这项研究中,年龄阶段,采用双性寿命表分析研究亚致死浓度的甲氨基阿维菌素苯甲酸酯和氯丁烯丙酯对一汽发育和繁殖的影响。在F0代,暴露于甲氨基阿维菌素苯甲酸酯和氯丁虫对一汽的持续时间有显著影响，从而延长了每一龄的发育时间，但不是产前阶段。此外，F0代LC25代的甲氨基阿维菌素苯甲酸酯和LC25代的氯苯三脲可显着降低一汽p的重量。关于繁殖力，甲氨基阿维菌素苯甲酸酯和chlantraniliprole显着降低了F0代的繁殖力。在F1一代中，LC10的甲氨基阿维菌素苯甲酸酯对成年期或成年期没有显着影响，而LC25显著缩短了成年期。在LC10和LC25暴露于chloantraniliprole的FAW成体和成体阶段显着延长。此外，甲氨基阿维菌素苯甲酸酯对F1代的蛹重没有显著影响。Chloantraniliprole对LC10没有显着影响，但在F1代的LC25时，p的重量显着降低。关于繁殖力，甲氨基阿维菌素苯甲酸酯显着降低了F1代的繁殖力。有趣的是,chloantraniliprole显着增加F1代的繁殖力，这可能会促进人口增长和害虫死灰复燃。研究结果对一汽病虫害综合治理具有重要意义,为一汽更有效的防治提供参考。
