| 摘 要： | 为明确浙江菜区斜纹夜蛾对主要杀虫剂的抗药性发展趋势，采集了浙江三门和萧山地区田间斜纹夜蛾，监测其对11种杀虫剂的敏感性水平。结果表明，三门种群和萧山种群对这些杀虫剂的敏感性存在明显差异，且萧山种群对测试药剂的敏感性高于三门种群。参考抗性诊断剂量（田间推荐浓度）处理后存活率和11种杀虫剂LC99致死浓度与田间推荐浓度的比值，推断三门种群对氯虫苯甲酰胺和溴虫腈敏感，对茚虫威、甲氨基阿维菌素苯甲酸盐、啶虫隆、丁醚脲和多杀菌素的敏感性下降，对虫酰肼、乙基多杀菌素、阿维菌素和高效氯氰菊酯已产生抗性；同样，萧山种群对氯虫苯甲酰胺、溴虫腈和多杀菌素敏感，对甲氨基阿维菌素苯甲酸盐、丁醚脲、啶虫隆、乙基多杀菌素、茚虫威、阿维菌素敏感性下降，对虫酰肼和高效氯氰菊酯产生抗性。因此，浙江菜区斜纹夜蛾对大部分监测杀虫剂的抗性正在形成，已产生抗性的高效氯氰菊酯、阿维菌素、虫酰肼应暂停使用1~2年；其余药剂则需要控制用药次数和采用不同种类杀虫剂轮用、混用的方式以延缓抗药性的产生。

| Abstract: | To characterize the developmental trend of resistance to insecticides of oriental leafworm moth （OLM）， Spodoptera litura， in Zhejiang province， the sensitivities to 11 insecticides of OLMs collected from Sanmen and Xiaoshan were studied and compared. Significant differences were shown between the data of OLMs from the two cities， i.e. the acquired sensitivities to 11 insecticides of OLMs from Sanmen were higher than those of OLMs from Xiaoshan. Refering to the survival rate of OLMs after treating at discriminating doses， together with the ratio of insecticidal LC99 to field recommended concentration， it could be deduced that OLMs in Sanmen was still sensitive to chlorantraniliprole， chlorfenapyr; sensitivities to indoxacarb， emamectin benzoate， chlorfluazuron， diafenthiuron， spinosad have declined; and resistances to tebufenozide， spinetoram and beta\|cypermethrin have developed. While the OLMs in Xiaoshan were sensitive to chlorantraniliprole， chlorfenapyr and spinosad; sensitivity to emamectin benzoate， diafenthiuron， chlorfluazuron， spinetoram， indoxacarb， abamection had declined， and resistances to beta\|cypermethrin have developed. Therefore， resistance levels of OLMs to most of the insecticides monitored were increasing in Zhejiang province， and beta\|cypermethrin， abamection， tebufenozide that OLMs had developed resistance should be stopped using for one or two years， and the rest still can be applied to control OLMs by the methods of limiting the frequency of spraying， rotation or mixture of different kinds insecticides in order to delay the development of resistance. |
