五种杀虫剂对烟草潜叶蛾的毒力测定

摘要

In order to scientifically apply insecticides to control the potato tuber moth [Phthorimaea operculella (Zeller)], the toxicities of five insecticides to eggs and larvae of potato tuber moth were tested in laboratory. The results showed that the descending order of toxicity of these five insecticides to eggs of potato tuber moth was cyhalothrin, decamethrin, emamectin benzoate, beta cypermethrin, fenvalerate. The results showed that the descending order of toxicity of these five insecticides to larvae of potato tuber moth was cyhalothrin, decamethrin, beta cypermethrin, fenvalerate, emamectin benzoate. In the controlling of this pest, cyhalothrin and decamethrin should be adopted.%　　为筛选出有效的烟草潜叶蛾防治药剂，试验了5种药剂对烟草潜叶蛾卵及幼虫的毒力。研究结果表明，五种药剂对烟草潜叶蛾卵的毒力排序为三氟氯氰菊酯＞溴氰菊酯＞甲氨基阿维菌素苯甲酸盐＞高效氯氰菊酯＞氰戊菊酯；五种药剂对烟草潜叶蛾幼虫的毒力排序为三氟氯氰菊酯＞溴氰菊酯＞高效氯氰菊酯＞氰戊菊酯＞甲氨基阿维菌素苯甲酸盐。因此在防治中可选用三氟氯氰菊酯和溴氰菊酯对烟草潜叶蛾进行药剂防治。
