| 摘 要： | 通过人工接虫、室内试验和田间调查的方法分析亚洲玉米螟幼虫的取食位置．结果表明幼虫在分散前集中在未抽出的雄穗上取食，分散后主要取食玉米中部的茎和雌穗；喇叭口期以前的幼虫为害虽然造成花叶，但其成活率很低，对玉米影响不大。建议在玉米抗螟性鉴定时应考虑玉米茎和雌、雄穗对幼虫的作用，在防治时采用喇叭口末期集中施药和抽雄期适当去雄的方法。

| Abstract: | This study was conducted with artificial infection,laboratory test and field investigation. The results in-dicated that the larvae fed early tassels together before tasseling, then they bored in mid-stem and ears aftertasseling.Before whorl stage there was little effect of larvae on corn plants although they fed leaves.The re-sults suggest that the application of pesticdes should concentrate on late-whorl stage associating with distas-seling, and screening for host-plant resistance should concentrate on resistance in the stem and the tassel. |
