摘要 :2018年底草地贪夜蛾Spodoptera frugiperda入侵我国,2019年在我国大规模迁飞扩散。山东省地处草地贪夜蛾的重点防范区,我们在山东省的30个监测点利用性诱方法监测了草地贪夜蛾在山东省的迁飞路径、分布和发生动态。结果显示:总共诱捕到428头草地贪夜蛾,其中97%以上个体分布在胶东地區,推测东部沿海是其在山东省南北迁飞的主要路径;6月20日在郯城监测点首次监测到1头草地贪夜蛾成虫, 9月中旬至10月中旬监测到其余的427头,在此阶段草地贪夜蛾可能有4次从南向北的迁飞。随着草地贪夜蛾在我国定殖和种群扩张,亟需探索高效的草地贪夜蛾早期监测技术,建立网络化监测预警体系和区域性防控体系。

Abstract :Fall armyworm, Spodoptera frugiperda invaded China in the end of 2018, and widely migrated in 2019. Shandong province is the key prevention area for fall armyworm, a total of 30 monitoring stations were set and pheromone trapping method was used to monitor the migration, distribution and population dynamics of the pest in 2019. Totally 428 fall armyworm individuals were trapped, and more than 97% of them were trapped in Jiaodong area, which indicated that the east coast may be the main migration route of fall armyworm in Shandong province. The first fall armyworm adult was trapped in Tancheng station on June 20, and the other 427 adults were trapped from the middle of September to the middle of October. There might be four times migration from south to north in this period. With the colonization and expansion of fall armyworm in China, the establishment of effective early monitoring method, monitoring and warning system and regional management system is becoming urgent.

草地贪夜蛾Spodoptera frugiperda是一种源自美洲的重大迁飞性害虫[1],2018年12月草地贪夜蛾入侵我国[2]。据报道,草地贪夜蛾寄主范围广,为害的作物包括玉米、棉花、水稻、小麦、花生、大豆、马铃薯、果树等80余种[3],几乎涵盖了我国的主要作物,同时其具有极强的远距离迁飞、繁殖能力和暴发为害的特点,对我国的农业安全造成了严重的威胁。
山东省是我国玉米主产区之一,常年播种面积和总产量约为300万hm2和2 000万t,占全国的9%左右[4]。山东省地处我国迁飞性害虫南北迁飞重要通道上,草地贪夜蛾伴随西南季风迁入山东省,正值夏玉米生长的苗期和喇叭口期,可能对山东省的夏玉米生产造成极大危害[5],杨普云等将山东省所在的黄淮海地区划为草地贪夜蛾重点防范区[6]。……
