中文摘要: 甜菜夜蛾Spodoptera exigua (Hübner)是世界性农业害虫,近年来在我国由次要害虫上升为主要害虫。甜菜夜蛾对很多种化学杀虫剂和生物杀虫剂产生了抗性。本文分别阐述了甜菜夜蛾对常用杀虫剂如有机磷类、拟除虫菊酯类、氨基甲酸酯类、生长调节类杀虫剂、Bt 杀虫剂等的抗性发展现状,并且对抗药性机理进行了总结,提出了抗性治理措施。
英文摘要:Spodoptera exigua ( Hübner) is a worldwide pest,in recent years moving from secondary to primary peststatus. It has developed significant resistance to many chemical and biological control agents. In thispaper,the resistanceconditions of S. exigua to organophosphate,pyrethroid,carbamate and growth regulation insecticides and to Bt toxins aredescribed,the mechanisms of resistance are discussed and tactics for managing resistance are mentioned.
