| 中文摘要: |
| 采用浸卵法测定了15种杀虫剂对草地贪夜蛾卵的毒力,并比较了不同杀虫剂的毒力水平。结果表明:100 mg/L处理后48 h,甲氨基阿维菌素苯甲酸盐(甲维盐)和灭多威对草地贪夜蛾卵孵化抑制率最高,达到100%,其LC50分别为12.67 mg/L和16.95 mg/L;而200 mg/L的氯虫苯甲酰胺、多杀霉素、阿维菌素、高效氯氰菊酯、虱螨脲、辛硫磷和杀螟丹分别处理后72 h对草地贪夜蛾卵的孵化抑制率次之,在69.6%~87.65%之间,其LC50分别为44.1、50.9、78.37、79.0、98.15、126.8 mg/L和137.7 mg/L。依据毒力测定的结果和高效低毒类杀虫剂优先选用的原则,推荐选择甲维盐、氯虫苯甲酰胺、多杀霉素、阿维菌素和高效氯氰菊酯作为防治草地贪夜蛾卵的主要药剂。 |
| 英文摘要: |
| Using egg dipping method, the toxicities of 15 insecticides to eggs of Spodoptera frugiperda were tested under laboratory conditions. The results showed that 48 h post treatment with 100 mg/L of emamectin benzoate and methomyl, the hatching inhibition rates to eggs of S. frugiperda both reached 100%, and their 50% lethal concentration (LC50) values were 12.67 mg/L and 16.95 mg/L, respectively. And 72 h post treatment with 200 mg/L of chlorantraniliprole, spinosad, abamectin, beta cypermethrin, lufenuron, phoxim, and cartap, the hatching inhibition rate to eggs ranged from 69.6% to 87.65%, and their LC50 values were 44.1, 50.9, 78.37, 79, 98.15, 126.8 mg/L and 137.7 mg/L, respectively. Based on these results, to use emamectin benzoate, chlorantraniliprole, spinosad, abamectin, or beta cypermethrin as the main ingredients were recommended for the control of S. frugiperda eggs. |
