摘要
通过室内饲养与田间系统调查，应用生命表方法研究了５ 种杀虫剂对小菜蛾种群的控制作用，结果表明：对小菜蛾种群控制作用效果最好的杀虫剂是１ ．８ ％ 集琦虫螨克，其干扰作用控制指数为０．１５４；其次为：菜蛾敌粉剂、１ ％ 农哈哈、２．５％ 功夫和４５ ％ 马拉硫磷，其干扰作用控制指数分别为０ ．１９５ 、０ ．２０７ 、０ ．３０２ 和０．３５９ ．
In this paper, the data in the life table and the indices of population control were applied to the evaluation of the control effects of the insecticides on the population of Plutella xylostella (L.).The results showed that the control effect of JiQi Chongmanke on the population dynamics of Plutella xylostella (L.) was better than the other insecticides’,and its interference index of population control(IIPC) was 0.154.The IIPC of Caiedi,Jiengangmygin,Cyhalothrin and Malathin were 0.195,0.207,0.302 and 0.359,respectively.
