草地贪夜蛾的昆虫病原微生物资源及其应用现状

昆虫病原微生物是广泛存在于自然界并能调控昆虫种群数量动态的一类重要自然资源。我国独特的地理位置、丰富的植物资源、适宜的气候条件等因素促使草地贪夜蛾Spodoptera frugiperda(J. E. Smith)在我国将呈现周年常态化发生态势,因此草地贪夜蛾的防控工作将是一项长期的重大任务。本文整理了草地贪夜蛾的昆虫病原微生物资源,概述了昆虫病原微生物在草地贪夜蛾防控工作中的应用现状,就其现状指出了存在的问题并为未来的发展提出了相应的建议,旨在为更好地利用昆虫病原微生物防控草地贪夜蛾提供参考。

Entomopathogen resources of the fall armyworm Spodoptera frugiperda, and their application status

Entomopathogen are a kind of major natural resources which exist widely in nature and can regulate the dynamic of insect population. Spodoptera frugiperda (J. E. Smith) will present a trend of annual occurrence due to the unique geographical location, abundant plant resources and suitable climatic conditions in China. Therefore, the prevention and control of this seriously threatening species will be a long-term arduous task. This paper summarized the entomopathogen resources of fall armyworm and outlined its application status in controlling fall armyworm. Finally, in order to provide references for the better control of S. frugiperda via these resources, we also raised some problems faced for application status, and meanwhile gave some advices for its future development.
