The integrated use of plant-derived volatile attractants and synthetic insecticides in attract-and-kill programs is a useful tool for integrated pest management programs reducing pesticide input. Efficient alternative insecticides are critically needed to replace methomyl, which has been banned on cruciferous vegetables in China because it is also highly toxic to nontarget organisms. In the present study, among 15 commonly used insecticides were screened for toxicity against moths, where chlorantraniliprole, flubendiamide, and emamectin benzoate was found to have the highest levels of toxicity (LC of 0.56, 3.85, and 6.03 mg a.i. L respectively). After exposure to the low lethal concentration LC of chlorantraniliprole, fecundity of the moths was substantially reduced. Egg-hatching was lower for LC- and LC-treated moth pairs than for untreated control pairs. Net reproductive rate (), intrinsic rate of increase (), and finite rate of increase () were significantly reduced in LC♀ × LC♂ cohorts. Larval mortality was significantly higher in subsequent generations in pairs of LC-treated moths. Chlorantraniliprole, which was most toxic and had significant sublethal effects on moths, can be used as an alternative insecticide to methomyl in the attracticide for controlling moths, and the LC indicated a high potential for efficacy in the control through attract-and-kill schemes.
在诱捕杀灭方案中综合使用植物源挥发性引诱剂和合成杀虫剂，是减少农药投入的有害生物综合治理方案的一项有用工具。迫切需要高效的替代杀虫剂来取代灭多威，在中国，灭多威已被禁止用于十字花科蔬菜，因为它对非靶标生物也具有高毒性。在本研究中，对15种常用杀虫剂进行了针对蛾类的毒性筛选，其中氯虫苯甲酰胺、氟苯虫酰胺和甲氨基阿维菌素苯甲酸盐的毒性最高（LC分别为0.56、3.85和6.03毫克有效成分/升）。暴露于氯虫苯甲酰胺的低致死浓度LC后，蛾类的繁殖力大幅降低。LC-和LC处理的蛾类配对的卵孵化率低于未处理的对照配对。在LC♀×LC♂群体中，净生殖率（）、内禀增长率（）和有限增长率（）显著降低。LC处理的蛾类配对的后代幼虫死亡率显著更高。氯虫苯甲酰胺对蛾类毒性最高且具有显著的亚致死效应，可作为灭多威的替代杀虫剂用于诱捕剂中以防治蛾类，并且LC表明通过诱捕杀灭方案在防治方面具有很高的功效潜力。
