【摘要】 在1989～1991年,对板栗主要四种害虫—栗瘿蜂[Dryocosmus Kuriphilus(Yasumatsu)]、栎剪枝象[Cyllorhynchites ursulus(Roelofs)]、栗绛蚧(Kermes nawae Kuwana)、栗实象鼻虫(Curculiodavidi Fairmaire)的生物学特性、主要天敌、发生规律、预测预报技术、综合防治技术及农药氧化乐果在板栗树中杀虫机理等作了研究,总结出一套以测报为耳目、营林措施为基础、化防为应急、人工灭虫和保护天敌为补充的板栗害虫综合防治技术。经三年累计综合防治1.5万亩,增产栗子28.74万kg, 增加产值120.7万元,为综防总投资(15.6万元)的7.74倍。效益明显,宜于推广应用。更多还原
