综合防治棉铃虫的区域性技术体系研究

REGIONAL TECHNIC SYSTEM OF INTEGRATED MANAGEMENT AGAINST THE RAMPANT DAMAGE OF COTTON BOLLWORM IN NORTH CHINA

研究改进了棉铃虫中期预报方法；提出“一代监测、二代保顶、三代保蕾、四代保铃”为主的防治策略；研究制定适用于不同世代、不同水肥条件的科学防治指标，协调应用多种配套措施保护、利用自然天敌控害，系统监测和治理棉铃虫抗药性；利用棉花种质资源和品种的抗病、抗虫性；诱杀成虫；组建大面积综防技术体系。在１９９２～１９９５年棉铃虫猩獗发生的情况下，于河南省新乡县棉花病虫害综防示范区大面积实施后，有效控制了棉铃虫危害。

Based on the advances in researches of cotton IPM techniques, a complete set of key techniques dealt with the integrated management of CBW was developed and periodically practiced in accordance with the development stages of cotton and occurrence of CBW, which is very useful for the cotton farmers in Yellow River Valley to control CBW.
