草地贪夜蛾的生物学特性及治理策略

Biological Characteristics of Fall Armyworm(Spodoptera frugiperda)and the Management Strategy for This Pest

草地贪夜蛾是一种夜蛾类杂食性害虫,主要为害玉米、高粱等禾本科植物,是全球预警的重要农业害虫.该虫于2019年1月传入我国,已经蔓延到我国的20个省(市、区),是目前各级政府十分关注的农业有害生物防控对象.本文系统介绍了草地贪夜蛾的生物学特性,以及该虫的关键控制技术,提出了以生态调控为核心的治理对策,以便各地行政和技术人员更好地认清该虫的为害本质,为有效推进该虫综合治理提供技术支持.

Grassland noctuid moth (Spodoptera frugiperda),whose larva is called fall armyworm,is an omnivorous pest of noctuid moth,which mainly harms gramineous plants such as maize and sorghum and is an important agricultural pest for global early warning.The pest migrated into China in January,2019 and has since spread to 17 provinces/municipalities/autonomous regions in China.It is the object of agricultural pest control that governments at all levels pay close attention to.This paper systematically introduces the biological characteristics of S.frugiperda and the key control technology of the moth,and recommends ecological control,in order to better understand the harmful nature of the moth and provide technical support for effectively promoting the integrated control of this pest.
