9种药剂对斜纹夜蛾的室内毒力与田间应用效果

The toxicity and control efficiency of 9 insecticides to Spodoptera litura

通过室内毒力测定和田间药效试验,测定当前9种主流杀虫剂产品对斜纹夜蛾的防治效果。结果表明,甲维盐、茚虫威、虫螨腈和虫酰肼对斜纹夜蛾具有优良的防效,可作为防治斜纹夜蛾的首选药剂。Bt与多杀菌素的效果次之。阿维菌素、高效氯氰菊酯和毒死蜱对斜纹夜蛾已逐渐失去控制作用,在生产中应尽量少用、慎用。

The toxicity of 9 mainstream insecticides against Spodoptera litura （Fabricius） was tested in the laboratory and fields. The results showed that emamectin benzoate, chlorfenapyr, indoxacarb and tebufenozide had efficient control to S. litura, followed by Bt and spinosad. They could be the first choice in chemical control of S. litura. However, abamectin, beta-cypermethrin and chlorpyrifos had poor effects on S. litura and should be used carefully in the field.
