摘　　要：比较了5种不同类型的生物农药对葡萄上小绿叶蝉、蓟马、绿盲蝽的防治效果。结果表明,5种农药的推荐剂量对3种葡萄害虫具有不同的防治效果:苦参碱对3种害虫的防治效果最好,药后3 d对小绿叶蝉、蓟马、绿盲蝽的防效分别为89.6%、80.5%、77.5%;其次为复合楝素,药后3 d对3种害虫平均防效在70.0%以上;除虫菊素、鱼藤酮、复合烟碱对3种害虫的防治效果相对较差。苦参碱和复合楝素可作为化学农药替代品应用于葡萄生产。The control efficacy of five biological insecticides against empoasca flavescens, frankliniella intonsa and lygus lu- corum were comparatively analyzed. The results showed that five biological pesticides had different control effects on three kinds of pests. Matrine had the best control effect on those pests with efficiency for empoasca flavescens, frankliniella intonsa and lygus lucorum of 89.6%, 80.5% and 77.5% after 3 days, respectively. The composite toosedarin had an average control efficacy above 70.0% for three pests after 3 days. The control effects of pyrethrin, rotenone and composite nicotine were rel- atively weaker. Matrine and composite toosedarin can be used as the substitute biological insecticides in grape production.
