水稻重要害虫防治的杀虫剂应用及关键技术研究进展

Advancements on the insecticides application and key technique in the control of disaster pests in paddy field

水稻作为我国重要的粮食作物,其害虫防治直接关系到国家粮食安全。化学杀虫剂作为当前水稻害虫防治中不可或缺的工具,对于控制害虫数量、减少作物损失和保障粮食产量发挥着关键作用。然而,长期不合理使用杀虫剂导致了害虫抗药性的产生,给水稻害虫的科学防控和粮食安全带来挑战。概述了我国水稻重要害虫稻飞虱、二化螟和稻纵卷叶螟的发生与危害,化学防治药剂的发展历程及抗药性现状,并对当前水稻田杀虫剂应用及关键技术进行了综述,以期为实现我国水稻害虫的科学防控、提高杀虫剂利用效率和防治效果,进而为推动水稻产业的可持续发展和保障我国粮食安全提供指导。

Rice is the subsistence crop in China,chemical control in paddy is the important measure to ensure its yield and food security.However,the long term or abuse of insecticides has caused resistance developed and the challenge on pest control and sustainable rice production.The current prevalence of key rice pests,including rice planthopper(Nilaparvata lugens,Sogatella furcifera,Laodelphax striatellus),stripped stem borer(Chilo suppressalis),and rice leaf fodder(Cnaphalocrocis medinalis),and the development of chemical insecticides and resistance status were reviewed in this paper,the key technique of the insecticide application was also suggested to guide the insecticide scientific application in paddy and enhance the efficiency of insecticide,the aim was to ensure the sustainability of rice industry and food safety.
