草地贪夜蛾迁飞行为与监测技术研究进展

草地贪夜蛾Spodoptera frugiperda原产于美洲的热带和亚热带地区,广泛分布于美洲大陆。2016年入侵到非洲,迅速蔓延到撒哈拉以南的整个区域。2018年入侵到印度。联合国粮农组织(FAO)发出警告,草地贪夜蛾很有可能从印度蔓延到东南亚及中国南部为主的亚洲地区。为掌握草地贪夜蛾在国外的发生与迁飞为害规律,加强我国对草地贪夜蛾的入侵控制和监测预警,本文综述了草地贪夜蛾在美国、加勒比海国家、墨西哥以及非洲国家的迁飞行为规律、性诱剂、灯光诱捕以及迁飞路径的分子鉴定等监测预警技术的研究进展,从而为我国植保人员对该虫的监测提供技术指导。针对草地贪夜蛾在世界范围内的迁飞规律和入侵特点,结合我国农作物种植结构以及气候特点,提出加强对草地贪夜蛾的监测与检疫的建议。

Advances in migration and monitoring techniques of the fall armyworm, Spodoptera frugiperda (J. E. Smith)

The fall armyworm, Spodoptera frugiperda (J. E. Smith), is native to tropical and subtropical regions of the Americas and widely distributed in the American continent. It invaded Africa in 2016 and thereafter spread rapidly to the entire sub-Saharan region. In 2018, it was firstly reported in India. Food and Agriculture Organization (FAO) has warned that the species is likely to spread from India to Southeast Asia and southern part of China. To better understand the occurrence and migration of this species in the world, as well as to strengthen its monitoring and early warning technologies and invasion control in China, the research advances in the migration, sex pheromone trap, light trap and molecular identification of migrant population source of the fall armyworm in America, Caribbean, Mexico and African countries were summarized; we hope this review will provide some technical guidance for monitoring the species invading China. Finally, according to the features of migration and damage caused by the fall armyworm in the world, combined with the planting structure of crops and climate characteristics in China, we put forward some suggestions for strengthening the monitoring and quarantine of the fall armyworm in China.
