二点委夜蛾是2005年在河北省新发现的玉米害虫,近年来在我国夏玉米种植区发生日趋严重。为研究二点委夜蛾是否有向冷凉地区扩散的习性,证明二点委夜蛾主害代为害玉米以后是否迁移到其他地区,在河北省易县选择不同海拔高度和不同地貌类型的地区进行了定点诱测试验。其中,在平原地区设置2个测试点,利用诱虫灯诱集,作为对照（CK）;在低海拔地区设置1个测试点、在高海拔地区设置3个测试点,均利用性诱剂进行诱集。结果表明：二点委夜蛾主害代没有发生的春玉米区,8～9月也没有发现其成虫;7月发生为害的平原区,8～9月有成虫活动,且7月发生越严重的区域,8～9月成虫量越高;高海拔地区未诱测到二点委夜蛾成虫。在河北省易县,二点委夜蛾主害代以后的时期,成虫未向高海拔冷凉地区迁移。

The trapping to Athetis lepigone with sex attractant were tested in different altitude areas and different geomorphological types in Yi County.The results showed that from August to September no adult were found in the spring maize area where the main injurious generations didn＇t occur,and the adult amount was higher in plain area where it occurred seriously in July.No adult were trapped in high altitude area.After the main injurious generations,the adult did not transfer to the cool high altitude area.
