草地贪夜蛾综合防控技术研究进展

草地贪夜蛾是世界重大入侵性害虫,我国于2019年初发现草地贪夜蛾大面积危害西南地区玉米、高粱、甘蔗等多种作物,随后迅速扩散至主要玉米产区,严重威胁和影响我国粮食安全。国内研究人员已开展了大量关于草地贪夜蛾监测预警与防控技术的研究,在其种群发生规律监测、迁飞路径研判、化学防治、生物防治、物理防治等方面取得了系列进展,基本明确了草地贪夜蛾在我国西南、江南江淮、北方各地区的发生与危害规律,建立了一套草地贪夜蛾综合防控技术体系,有效阻断了其大面积扩散危害。本文综述了2019—2022年间国内草地贪夜蛾防控技术的研究进展,以期为开发草地贪夜蛾综合防控技术提供参考。

Research progress on comprehensive control techniques of the fall armyworm, Spodoptera frugiperda, in China

The fall armyworm, Spodoptera frugiperda (J. E. Smith), is a highly invasive species of global concern. In early 2019, it affected and caused extensive damage to a large area of corn, sorghum, sugarcane, and other crops in southwest China. It has since quickly spread to major corn-producing regions, posing a serious threat to China''s food security. Domestic researchers have extensively monitored the spread, and developed warning and prevention strategies. Substantial progress has been made in tracking S. frugiperda population patterns, tracking migration routes, and implementing chemical, biological, and physical control measures. This extensive research effort effectively outlined the occurrence and damage patterns of S. frugiperda in the southwest, south of the Yangtze River, Yangze river and Huai river, and regions of northern China. The established comprehensive control system for S. frugiperda has effectively blocking its widespread infestation. In this review, we discuss the research progress on prevention and control for S. frugiperda in China from 2019 to 2022. Our objective is to provide a valuable reference for further improving the biological control of S. frugiperda in China.
