摘　　要：利用棉铃虫（Ｈｅｌｉｃｏｖｅｒｐａ ａｍ ｉｇｅｒａ）性信息素诱蛾，预测下一代棉铃虫的卵高峰，幼虫孵化高峰，通过田间调查印证是准确的，它比黑光灯诱蛾以及田间调查方法简便，省工省时，指导化学农药防治时间准确，经济效益明显。可为棉铃虫发生期预测预报增添一种新的有效方法。The peaks of egg laying and larva hatching of the cotton bollworm, Helicoverpa armigera can be accurately predicted by using its synthetic sex pheromones in the cotton field for trapping the male moths.This method is better than others and has been shown as a new and effective mean for prediction of the occurrence of the cotton bollworm.
