近年来,鲁西北地区春玉米面积减少,麦套棉面积不断扩大,一代玉米螟在棉田为害日趋严重,成为棉花的重要害虫之一。一般减产10％左右,为害严重的减产达30％以上。自1984年以来,我们对鲁西北地区棉田一代玉米螟发生与防治进行了系统研究,取得了良好防治效果。 In recent years, the area of ​​spring maize in northwestern Shandong has been reduced, and the area of ​​wheat straw has been continuously expanded. The damage caused by one generation of maize borer in the cotton field has become increasingly serious and has become one of the important pests of cotton. The general reduction of about 10%, serious damage reduced by more than 30%. Since 1984, we conducted a systematic study on the occurrence and control of the first generation corn borer in the cotton field in the northwest of Shandong Province and achieved good control effects.
