【摘要】 根据安徽省2019—2021年的田间调查监测数据，结合室内饲养试验进行统计分析，归纳了安徽省草地贪夜蛾的虫源性质及发生规律，预测了该虫的发生趋势。结果表明，草地贪夜蛾在安徽省已经成为常发性迁飞害虫，发生区域遍布全省玉米种植区，且基本稳定，2019—2021年16个市均发生为害，发生县(区)数量有减少趋势，3年分别为89、80、72个；发生为害面积有一定差异，但发生面积占玉米种植面积的比例均低于1%,3年发生面积分别为6 546、3 099和3 894 hm~2,占比分别为0.52%、0.22%和0.31%;预计2022年草地贪夜蛾在安徽省总体偏重发生，发生面积约13万hm~2,春玉米中等发生，夏玉米偏轻发生，秋玉米大发生，沿淮淮北局部地区小麦苗期集中为害。更多还原

【Abstract】 Based on the field survey and monitoring data from 2019 to 2021 in Anhui Province and together with the indoor feeding experiment, the source properties and occurrence regularity of Spodoptera frugiperda in Anhui Province were summarized and further the occurrence tendency was also predicted. The following conclusions are: Spodoptera frugiperda has become a common migratory pest in Anhui Province with the occurrence area over all the corn growing area, and it was basically stable. From 2019 to 2021, Spodoptera frugiperda was found in all 16 cities but the number of counties(districts) decreased, which was 89, 80, and 72 in three years, respectively. There were differences in the occurrence area, however, the proportion of the occurrence area was less than 1% and the occurrence area was 6 546, 3 099, and 3 894 hm~2 in three years(accounting for 0.52%, 0.22%, and 0.31%), respectively. It is expected that Spodoptera frugiperda will occur more seriously in Anhui Province in 2022 and the estimated damaged area is about 130,000 hm~2, with moderate occurrence in spring maize, light occurrence in summer maize, and large occurrence in autumn maize. Besides, the concentrated damage in wheat seedling stage will occur along the north of Huaihe River in local area.更多还原
