| 摘 要： | 研究了黄瓜大田内几种常用杀虫剂对烟粉虱种群数量的控制作用,结果表明：阿维菌素、吡虫啉和扑虱灵均是防治烟粉虱较好的杀虫剂,其中以吡虫啉效果最佳,其干扰作用控制指数为0．0472,表明吡虫啉施用区烟粉虱的种群数量只相当于对照区的4．72％,其次为阿维菌素和扑虱灵,其干扰作用控制指数分别为0．1019和0．1551．由于烟粉虱对乐果等有机磷杀虫剂具有较强的抗性以及乐果对天敌的杀伤,乐果施用区内烟粉虱出现大量发生和猖獗危害现象,干扰作用控制指数达到1．0762,即烟粉虱种群数量为对照区的1．0762倍,因此应该停止使用这类杀虫剂来防治烟粉虱．

| Abstract: | The experiment was conducted to estimate the influences of Abamectin, imidacloprid, buprofezin and dimethoate on Bemisia tabaci. The result showed that the imidacloprid was the most effective and its interference index of population control (IIPC) was (0.047 2), i.e. the population of B. tabaci in the imidacloprid-used area was 4.72% of the population in control, the next are abamectin and buprofezin, their IIPC are (0.101 9) and (0.155 1), respectively. The IIPC of the population of B. tabaci in dimethoate area was (1.076 2), this means the population of B. tabaci in the dimethoate application block was (1.076 2) times of that of the control. |
