- 摘要:
- 以小菜蛾为研究对象，采用浸叶法研究了6种杀虫剂对哈尔滨地区小菜蛾的室内毒力活性。结果表明：氯虫苯甲酰胺的毒力最高，LC50仅为0.99 mg/L，高效氯氰菊酯的毒力最低,LC50达到50.08 mg/L，6种药剂对小菜蛾的毒力从大到小依次为氯虫苯甲酰胺>多杀菌素>苏云金芽孢杆菌（Bt）>丁酯脲>阿维菌素>高效氯氰菊酯，故氯虫苯甲酰胺可作为哈尔滨地区小菜蛾防治的首选药剂。
- Abstract:
- Taking Plutella xylostella L.as research object，six insecticides were investigated for their indoor toxicities against Plutella xylostella L.collected from Harbin area by leaf-dipping method.The results indicated that the toxicity of Chlorantraniliprole to Plutella xylostella L.was the hightest and the LC50?was only 0.99 mg/L，the toxicity of Alpha-cypermethrin to Plutella xylostella L. was the lowest and the LC50?was 50.08 mg/L.The toxicities of six insecticides were Chlorantraniliprole>Spinosad>Bacillus thuringiensis>Diafenthiuron>Abamection>Alpha-cypermethrin，Therefore，Chlorantraniliprole could be used as the preferred insecticide for control Plutella xylostella L.in Harbin area.
