摘　　要：豇豆是我国热区农民冬春季增收的主要蔬菜作物之一。由于气候适宜病虫害多发重发,导致防治难度大、化学农药使用多,农药残留超标风险大。经过3年多的研究与实践,初步构建了适宜海南等热区豇豆生产的“防虫网+”IPM技术体系。综合分析认为,该技术体系对大幅减少化学农药使用量、增加豇豆产量和提升质量安全水平具有明显效果,经济、生态和社会效益显著,并提出加大推广“防虫网+”IPM技术体系的对策建议。Vigna unguiculata(L.)Walp.,commonly known as cowpea,is a prominent vegetable crop cultivated by farmers in the tropics to augment their winter and spring incomes.However,the prevalent occurrence of diseases and insect pests in these favorable climatic conditions poses significant challenges to pest control.Consequently,chemical pesticide usage becomes necessary,which entails a risk of excessive pesticide residue.After more than three years of research and practice,the technical system of‘insect-proof net plus’integrated pest management(IPM)suitable for cowpea production in Hainan and other hot areas was preliminarily established,which has demonstrated marked effectiveness in reducing the reliance on chemical pesticides,ensuring increased cowpea production and elevating quality and safety standards.Additionally,the economic,ecological,and social benefits of this system are remarkable.On this basis,recommendations for the widespread adoption of an‘insect-proof net plus’IPM technology system are proposed.
