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0.99mg/L,高效氯氰菊酯的毒力最低,LC50达到50.08mg/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。
Taking Plutella xylosteUa L. as research object, six insecticides were investigated for their indoor toxicities against Plutella xylosteUa 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, Chloramraniliprole could be used as the preferred insecticide for control Plutella xylostella L. in Harbin area.
