摘　　要：为明确草地贪夜蛾在贵州省黔东南州的越冬情况,运用田间调查和性诱、灯诱等方法,对贵州省剑河、三穗、天柱、黎平、从江和榕江县草地贪夜蛾的越冬情况进行了调查。于2019年12月25日在从江县发现草地贪夜蛾的6龄幼虫和蛹各1头;2020年3月26日,在榕江县监测到成虫1头。推测草地贪夜蛾在黔东南州的低纬度低海拔地区有越冬的可能。玉米是草地贪夜蛾幼虫的主要越冬寄主,在被调查的白菜、油菜、姜黄、甘蔗、黑麦草、菠菜、葱、辣椒、黄豆和黄瓜上均未发现草地贪夜蛾。研究结果为掌握草地贪夜蛾在贵州省的越冬情况奠定了基础。To clarify the overwintering s ituation of Spodoptera frugiperda in the Southeast of Guizhou Province, we investigated the overwintering dynamics of S. frugiperda in Jianhe, Sansui, Tianzhu, Liping, Congjiang, and Rongjiang counties of Guizhou Province by conducting field survey, sex pheromone trapping and light trapping. The results showed that only one 6-instar larva and one pupa of S. frugiperda were found in Congjiang on December 25, 2019, and one adult was detected in Rongjiang on March 26, 2020. It could be speculated that S. frugiperda might overwinter in the low-latitude and low-altitude areas of the Southeast of Guizhou Province. Corn was the main overwintering host for S.frugiperda larvae. No S. frugiperda was found on the investigated cabbage, rape, turmeric, sugar cane, ryegrass, spinach,green onion, pepper, soybean, and cucumber. The results lay a foundation for uncovering the overwintering state of S.frugiperda in Guizhou Province.
