草地贪夜蛾的综合防治

草地贪夜蛾Spodoptera frugiperda (J. E. Smith)属于入侵性农业害虫，其幼虫可以大量啃食玉米、高粱、水稻等多种农作物。草地贪夜蛾具有迁飞能力强、突发性、多产性、暴食性、杂食性、隐蔽性、钻蛀性、钻土性、夜出性、趋嫩性和独占性等特性，防治难度极大。对于入侵的暴发性害虫来说，化学防治依旧是目前能够在较短时间内控制其在我国大规模暴发的主要方法。虽然有很多昆虫都是草地贪夜蛾的天敌，但基本上没有足够用来防止作物受伤的措施。目前的防治措施主要包括物理防治、化学防治、生物防治，其中生物防治又可具体为植物源农药、性诱剂、生防菌、寄生蜂、寄生性天敌等。

Integrated control of Spodoptera frugiperda

Spodoptera frugiperda (J. E. Smith) is an invasive agricultural pest, whose larvae can feed on corn, rice, sorghum and other crops in large amounts. S. frugiperda has the characteristics of strong migration ability, sudden, prolific, gluttony, omnivorous, concealment, burrowing, earth-burrowing, nocturnal, tenderizing and exclusive, which is very difficult to control. For invasive and explosive pests, chemical control is still the main method to control the outbreak in China in a short period of time. Although S. frugiperda has many natural enemies, there were few actions to prevent crops from being damaged. At present, the prevention and control measures mainly include physical control, chemical control and biological control measures. Biological control measures can be divided to plant pesticides, sex attractants, biocontrol bacteria, parasitic wasps, parasitic natural enemies, etc.
