空中棉铃虫成虫诱捕以山上设灯诱蛾较市区上空性信息素诱蛾效果要好。市区上空性信息素诱蛾受夜间市区灯光干扰。运用诱虫灯在山顶诱测 ,实为经济、有效、切实可行的空中诱捕方法。在远离棉区的 1 0 0 m上空的江苏南通剑山山顶应用双波诱虫灯 ,灯诱棉铃虫蛾仍然数量大。与周围棉区灯诱棉铃虫比 ,雌蛾比例高 ,卵巢级别低 ,蛾峰期 1～ 3级卵巢占 81 .1 5 % ,世代发生比较明显 ,蛾峰日与周围棉区发生期接近。根据系统调查 ,剑山山顶诱虫灯所诱棉铃虫成虫显然不是当地虫源。从卵巢级别低的特点推测 ,棉铃虫蛾有远距离迁移扩散的可能性 Aerial Helicoverpa armigera trapped in the mountain light trap moth than the urban pheromone moth effect is better. Sex pheromones over the urban area were disturbed by nighttime lights at night. The use of trap light on the peak of the trap, it is economical, effective and practical method of aerial trapping. Two-wave trap light was applied to the top of Jian-Shan Mountain, Nantong, Jiangsu Province, which was more than 100 m away from the cotton area. There was still a large number of light-induced bollworm moths. Compared with the cotton bollworm around the cotton bolls, the proportion of female moths was high, the ovary level was low, and the ovaries of grade 1 ~ 3 ovaries accounted for 81.151% at the peak of moths. According to the systematic investigation, the insect trapped by the trap light on the top of JianShan Mountain is obviously not a local insect source. According to the characteristics of low ovarian level, it is speculated that H. armigera could migrate and disperse at a long distance
