害虫综合治理 (IPM)理论上的局限性使IPM的实施仍以有毒农药的使用为主要手段 ,结果合成农药销量有增无减 ,导致环境质量继续恶化 ,传统的植物保护对化学农药的依赖性越来越高。害虫生态管理 (EPM)已成为IPM的发展方向 ,它按照生态学、经济学和环境保护学的原理、原则和方法 ,在不断搜集有关信息、随时对系统进行监测与预测的基础上 ,以系统失衡时的虫口密度为阀值 ,采取自然控制与人工调节相结合的防治策略 ,维持生态系统的长期稳定性和提高系统本身的自我调控能力。随着耕作制度的改变、品种的更换、栽培技术的改进 ,稻田害虫群落也在发生相应的演变。因此 ,稻田害虫的管理对策要以作物为中心 ,以当地的主要害虫为对象 ,充分发挥天敌、品种、生境等自然因素对害虫的控制作用 ,开发关键技术 ,形成区域性的EPM模式 The theoretical limitations of integrated pest management (IPM) make the implementation of IPM still use toxic pesticides as the main means, resulting in an increase of sales of synthetic pesticides, resulting in the continued deterioration of environmental quality, the traditional plant protection dependence on chemical pesticides Higher and higher. The pest management (EPM) has become the development direction of the IPM. Based on the principles, principles and methods of ecology, economics and environmental protection, it continuously collects related information and monitors and forecasts the system at any time. The system Insect population density when the threshold for the threshold, to take natural and artificial control of the combination of prevention and control strategies to maintain the long-term stability of the ecosystem and improve the system’s ability to self-regulation. With the change of cultivation system, the change of breed and the improvement of cultivation techniques, the pest community in paddy fields also evolve accordingly. Therefore, rice field pest management strategies should focus on crops and take the local main pests as an object, and give full play to natural insect pests such as natural enemies, species, habitats and other natural factors to control the development of key technologies to form a regional EPM model
