| 摘 要： | 用浸叶法测定了陕西杨凌地区小菜蛾田间种群对阿维菌素等几种新型杀虫剂的敏感性。结果表明．田间种群小菜蛾对阿维菌素、氟虫腈、啶虫咪、溴虫腈、茚虫威、多杀霉素、甲胺基阿维菌素等的抗性倍数分别为2．75、1.65、1．10、1.27、1．16、1．14和1．32倍，结果表明，田间种群对大多数新型杀虫剂还没有产生明显的抗药性。

| Abstract: | Sensitivity of Plutella xylostella populations in Yangling, Shanxi Province, to several new insecticides was determined by a leaf dip method. Plutella xylostella populations showed resistance ratios to avermectin, fipronil, acetamiprid, chlorfenapyr, indoxacarb, spinosad, and emamectin benzoate of 2.75, 1.65, 1.10, 1.27, 1.16, 1.14, and 1.32, respectively. These results indicate that field populations of Plutella xylostella have no significant resistance to most new insecticides. |
