摘要
草地贪夜蛾2019年已经在中国南方和周边国家的热带、南亚热带地区完成定殖过程。自2020年起,将在春、夏两季随季风向北逐代迁移进入中国长江流域、黄河流域和东北小麦、玉米等重要农作物主产区发生为害,形成对国家粮食生产安全的长期性威胁。作者基于对草地贪夜蛾生物学习性和发生规律的认识,借鉴中国棉铃虫等重大农业害虫防控的经验教训,提出了中国草地贪夜蛾防控工作“两步走”策略。在近年内,实施以化学防治、物理防治、生物防治和农业防治为主的综合防治技术体系,旨在解决短期内生产上草地贪夜蛾为害的应急管控问题。然后通过现代农业信息技术和生物技术的创新与应用,力争在3~5年的时间内构建和实施以精准监测预警、迁飞高效阻截和种植Bt玉米为核心的综合防治技术体系,实现低成本、绿色可持续控制目标,满足中国农业生产高质量发展和社会生态文明建设的战略性需求。
In 2019,the fall armyworm has completed its colonization in the tropical and southern subtropical regions of China and neighboring countries.Beginning from 2020,it will move northward with the monsoon in spring and summer to enter the wheat,corn and other major crop production areas in the Yangtze River Basin,the Yellow River Basin,the Northeast region of China,which will pose a long-term threat to the national food production security.Based on the understanding of the biological behaviors and occurrence principle of fall armyworm and the practice experiences of the control of major agricultural pests such as cotton bollworm Helicoverpa armigera,the author puts forward the“two-step”strategy for the pest control in China.In recent years,the IPM strategy,mainly including chemical control,physical control,biological control and agricultural control,should be implemented in order to solve the problem of emergency management and reduce crop yield losses caused by the pest in the short term.Then,through the innovation and application of modern agricultural information technology and biotechnology,an IPM strategy based on accurate monitoring and early warning,high-efficient interception of moth migration and planting of Bt maize will be developed and deployed in 3-5 years,to achieve the goal of low-cost,green and sustainable control,and to meet the strategic needs of China's high-quality development of agricultural production and the construction of social ecological civilization.
