不同药剂对舞毒蛾和春尺蠖的毒力测定

Toxicity Test of Different Kinds of Insecticides to Lymantria dispar and Apocheima cinerarius

用3%高效氯氰菊酯、5%吡虫啉乳油、8%绿色威雷微胶囊剂3种无公害杀虫剂对常见园林食叶害虫舞毒蛾(Lymantria dispar(Linnaeus))、春尺蠖(Apocheima cinerarius Erschoff)进行了室内外的毒力测定,结果表明:3%高效氯氰菊脂2000倍液对舞毒蛾幼虫和春尺蠖幼虫毒杀作用效果最好,校正死亡率分别达到94.67%和94.83%。

An experiment was conducted to study the toxicity of three non-pollution insecticides against Lymantria dispar Linnaeus and Apocheima cinerarius Erschoff which are familiar in gardens both in the field and in the laboratory, including 3 percent beta-eypermethrin, 5 percent imidacloprid emulsion and 8 percent Luseweilei. Results indicated that 3 percent betaeypermethrin mierocapsalated suspension at a 2000 times dilution was the best insecticide to kill the larvae of L. dispar and A. cinerarius, and the adjusted mortality rates were 94.67 percent and 94.83 percent, respectively.
