| 摘 要： | 用浸叶法测定了6种杀虫剂对小菜蛾2龄幼虫的毒力。结果表明:6种杀虫剂对小菜蛾2龄幼虫毒力﹙LC50﹚大小顺序为0.3%印楝素乳油﹥溴虫腈﹥5%锐劲特悬浮剂>2%阿维菌素乳油>20%氰戊菊酯乳油﹥48%毒死蜱乳油。测定结果可以为合理选择杀虫剂及小菜蛾的田间防治提供依据。

| Abstract: | Toxicity of 6 insecticides to 2nd instar larvae diamondback moth(Plutella xylostella L)was determined by leaf dipping method.The results indicated that the orders of toxicity to Plutella xylostella L were 0.3% azadirachtin EC>chlorfenapyr>5%fipronil SE>2% abamectin EC>20% fenvalerateEC>48% chlorpyrifos EC.The results provided basis for reasonably insecticides choice and field control of Plutella xylostella L. |
