辽宁省春玉米区主要病虫害综合防治技术体系的建立、发展与展望

Establishment, Development and Perspective of Integrated Pest Management (IPM) of Maize Disease and Pest Insects in Liaoning Province

综述了辽宁省春玉米区主要病虫害综合防治技术体系的发展过程 ,介绍了不同发展时期玉米病虫害的综合防治策略和模式 ,评述了各时期综合防治技术体系的特点 ,认为辽宁省春玉米区的综合防治技术体系经济有效、实用性强 ,与社会发展环境相协调 ;并针对当前玉米生产上出现的次要病虫害与原来被控制的病虫害上升为主要病虫害 ,病虫害为害加重 ,病虫害灾变异常爆发时缺乏有效的应急防治措施等问题 ,从玉米生产可持续发展的角度 ,提出了加强主要病虫害中长期预警技术研究 ,增强自然控制力量 ,监测病原菌生理分化和潜在危险性病虫害发展动态的治理对策。

Process of the establishment and development of maize IPM in Liaoning Province was reviewed in this paper. The strategies and systems of IPM designed at various periods in the area were presented.Characteristics and role of maize IPM was appraised briefly. It was evaluated that maize IPM practised in Liaoning Province is an economic, practicable and compatible with the environment and development of societies. Also, the problems and current status of maize pest IPM was reported, such as secondary pests becoming major ones were pest resurgence and the lack of efficient control measures as pest outbreak. Finally, strategies for management of the problems was presented including major pests long-term forcasting, augumentation of natural control factors for maize pest, and monitoring the dynamics of pest with damage potential.
