【摘要】 草地贪夜蛾Spodoptera frugiperda原产于美洲热带和亚热带地区,是一种破坏性极强的害虫,可对近180种农作物造成破坏,严重威胁着粮食安全。草地贪夜蛾的迁飞能力强,成虫一晚能飞100 km以上,迅速传播。其自2019年入侵我国,已在26个省发现入侵和为害,并呈继续北迁的趋势,对草地贪夜蛾的防控将是一项长期重大的任务。目前,国内外对草地贪夜蛾防治主要以化学农药为主,但易致使其产生抗药性和造成环境污染,因此开发有效、低风险的防控方法以实现对草地贪夜蛾的可持续治理成为研究热点。生物防治是一种可有效替代化学防治的经济、环保的防控措施,主要是利用天敌昆虫(寄生性和捕食性昆虫)、病原微生物(如细菌、线虫、病原真菌、病毒)、植物源农药及性信息素等对害虫进行科学防治。本文总结了国内外关于草地贪夜蛾生物防治的研究进展概况,以期为今后科学防治草地贪夜蛾提供参考。更多还原

【Abstract】 Spodoptera frugiperda is an extremely destructive pest native to tropical and subtropical areas in the Americas. It causes devastating damage to almost 180 crop plants, posing a serious threat to food security. The remarkable flight capacity of over 100 km per night of the adult moths makes the infestation spread wide and rapid. Since 2019 when S. frugiperda first invaded China, 26 provinces have been affected by it with a threat of spreading farther to the northern part of the nation. Hence,the prevention and control of the pest is paramount but a long-term, arduous task. Application of chemical insecticides for the pest control is a common practice here and abroad but carries the inevitable side-effect of resistance development in the insects and pollution on the environment. As an ecologically friendly means, the use of biological agents would be an ideal alternative in effectively combating and sustainably managing the S. frugiperda infestation. This article summarizes the potential approaches cited in literature including the applications of entomophagous insects(i.e., parasitoids and predators), pathogenic microorganisms(e.g., bacteria, nematodes, pathogenic fungi, and viruses), plant-derived pesticides, and/or sex pheromone.更多还原
