摘　　要：草地贪夜蛾于2019年1月入侵我国云南省江城县,随后在多个省份发现其为害玉米,4月份以来在部分地区陆续发现其为害甘蔗、高粱等作物。作者于2019年10月5日在浙江省杭州市甘蓝上发现草地贪夜蛾高龄幼虫造成局部为害,平均每株幼虫0.62头,有虫株率达25%。建议今后加强蔬菜作物上该虫的监测和综合防控。The fall armyworm, Spodoptera frugiperda, was first found invaded in Jiangcheng county, Yunnan province, China, in January 2019. Since then the insect has been found on maize in many provinces. In addition, the insect has been found on sugarcane and sorghum in some areas of China since April, 2019. On October 5, 2019, we found high-instar larvae of S. frugiperda infesting cabbage Brassica oleracea L. in Hangzhou, Zhejiang province, with an average density of 0.62 larvae per plant and 25% infestation of plants. We thus suggest early monitoring of this insect pest on vegetable crops and implementation of integrated management when control is required.
