摘　　要：在正常播种的玉米田两侧晚播相同玉米品种或甜玉米品种,通过对正常播种区与晚播区二代玉米螟发生情况的系统调查分析得出,在正常播种的玉米田内局部晚播相同品种玉米或甜玉米能够明显降低二代玉米螟的发生和危害,二代玉米螟卵降低幅度在58%～76%。晚播的同品种玉米或甜玉米对二代玉米螟成虫产卵有较强的引诱作用,因而减轻了二代玉米螟在正常播种玉米田的发生和危害。This paper study that the occurrence of the second-generation Asia corn borer between the area of normal planting and late sowing in the maize field. The result shows that it can distinctly lower impairing of the second-generation Asia maize borer in the part of corn field to late sowing the same breed common corn or sweet corn. The extent of the second-generation Asia maize borer was decreased about 58% to 76%. We found that there was more powerful attracting actions to the imago of the second-generation Asia maize borer in the area of late sowing the same breed common corn or sweet corn, so it decrease the impairing of the second-generation Asia maize borer in the normal planting corn field.
