摘要：

二点委夜蛾Proxenus lepigone (M?schler)是中国玉米在2005年新发害虫，2011年暴发，发生范围扩大到6个夏玉米主产省，目前还没有针对性的防治措施及药剂。为了寻求防治二点委夜蛾的有效防控措施和理想的农药品种，采用9种药剂11个处理和毒土、毒饵两种施药方法进行田间试验，对用药前后被害株率进行测定。结果表明，辛硫磷、敌敌畏、毒死蜱、氯虫苯甲酰胺、敌百虫、高效氟氯氰菊酯6种药剂的毒土和毒饵法，对二点委夜蛾幼虫都有较好的防治效果，毒饵法对二点委夜蛾幼虫诱杀效果更为明显。同时还对这些药剂及施药方法在玉米苗期的安全性进行了评定，用毒死蜱防治后，7天内使用烟嘧磺隆类除草剂，玉米新叶会出现药害。

Abstract:

Proxenus lepigone (M?schler) is a new pest of corn in our. Country in the year of 2005, it abrupt break out in the year of 2011, scene has extended to six provinces of grow corn. Now, there is not pertinency measure and insecticide to control Proxenus lepigone. An experiment of nine pesticides with eleven treatments could be to control Proxenus lepigone, eleven treatments by divided into two techniques of insecticide mixed earth and insecticide mixed wheaten-bran. The results showed that: the six kinds of pesticides were effective to control Proxenus lepigone, these pesticides were phoxim, dichlorvos, chlorpyrifos, chlorantraniliprole, trichlorfon and cyhalothrin. The results showed that: the technique of insecticide mixed wheaten-bran was better prominent in the control efficiencies than the technique of insecticide mixed earth. At the same time, we made an assessment on the security to the small and tender crop about the nine pesticides and application methods in the experiment.
