摘　　要：草地贪夜蛾是玉米作物上近年来流行的害虫之一,对玉米产量安全影响较大。本研究采用高空测报灯、自动虫情测报灯和性诱剂监测连续3年调查了皖北地区草地贪夜蛾的发生情况。结果表明,草地贪夜蛾在该地区不能安全越冬,其初期危害虫源主要来自迁飞地。该地区草地贪夜蛾发生面积呈逐年下降趋势,且首次发现时间越来越晚。草地贪夜蛾在该地区一年可发生不完全4代,该害虫2代后世代重叠现象明显,为害严重。通过物理防治、生物防治、化学防治和农业防治等多种防治手段联合可以更加高效地防治草地贪夜蛾,使其发生危害较小。通过密切监测成虫迁入时间、迁入数量对实时防控草地贪夜蛾具有积极意义。Spodoptera frugiperda is one of the pest insects that have become prevalent in corn crops in recent years,posing a significant threat to the safety of corn yield.This study used skyradiosonde,automatic insect monitoring lamps,and sex pheromone traps to monitor the occurrence of Spodoptera frugiperda in the northern Anhui Province for three consecutive years.The results showed that Spodoptera frugiperda couldnot overwinter safely in this region,and the initial pest source mainly comes from migratory sources.The occurrence area of Spodoptera frugiperda in this region showed a decreasing trend year by year,and the first detection time was getting later and later.Spodoptera frugiperda could had an incomplete 4 generations per year in this region,and the phenomenon of overlapping generations was obvious after the second generation,causing severe damage.The combined use of physical,biological,chemical,and agricultural control methods can more effectively control Spodoptera frugiperda and minimize its harmful effects.Closely monitoring the immigration time and quantity of adults has positive significance for the real-time prevention and control of Spodoptera frugiperda.
