草地贪夜蛾对山东省玉米的危害风险及其监测防控研究进展

Potential Damage of Spodoptera frugiperda to Maize in Shandong Province and Research Progress on Its Monitoring and Control

草地贪夜蛾是一种原产于美洲热带和亚热带地区的重大迁飞性农业害虫,可以为害包括玉米、棉花、水稻、花生、大豆、马铃薯、小麦、果树等在内的80余种植物。2019年1月,该虫首次入侵我国云南省,截止5月10日,已在13省61市(州)261个县(市、区)为害玉米,发生面积7.2万公顷。伴随着西南季风,草地贪夜蛾可能继续北迁进入山东省,山东省夏玉米区是该虫种群繁殖、迁飞与再定殖的绝佳栖境。因此,必须早监测、早发现、早防控,减少其对全省玉米安全生产的威胁。本文总结了草地贪夜蛾的形态特征、为害特点、监测预警技术、防治措施并提出了对策和建议,以期为植保人员和相关科研人员对该虫进行监测预警和精准防控提供参考。

The fall armyworm(FAW),Spodoptera frugiperd,native to the tropical-subtropical regions of American continent,is one of the major migratory agricultural insect pests and feeds on more than 80 host plants including maize,cotton,rice,peanut,soybean,potato,wheat and fruit trees.In January 2019,this insect pest first invaded Yunnan Province,China.By May 10th,it had been detected to damage maize crop in 261 counties(cities or districts),61 cities(states),13 provinces,covering an area of 72 thousand hectare.FAW may continue to migrate north into Shandong Province with the southwest monsoon.The summer maize area of Shandong Province is an excellent habitat for reproduction,migration and re-colonization of FAW population.Therefore,early monitoring,early detection,early prevention and control methods must be taken to reduce its threat to the maize production in Shandong.In this study,we summarized the morphological characteristics,damage characteristics,monitoring and early-warning technologies,prevention and control measures of FAW.And several advices were also proposed.The aim is to provide information for persons of plant protection and related scientific researchers to monitor and early-warning and precise prevention and control on this insect pest.
