摘　　要：大棚内辣椒上释放东亚小花蝽Orius sauteri防治朱砂叶螨Tetranychus cinnabarinus、蓟马和蚜虫,并在苗期释放时利用天敌贮备植物万寿菊Tagetes eracta辅助建立种群。结果表明,按0.5头.m-2和1头.m-2释放东亚小花蝽对朱砂叶螨、蓟马在释放5～7周时防治效果达到97.20%～99.95%;对于蚜虫,按0.5头.m-2释放东亚小花蝽,防治效果仅22.78%,而1头.m-2释放防治效果最高可达96.39%。东亚小花蝽释放可以用于控制大棚辣椒小型害虫。Releasing Orius sauteri for controlling Tetranychus cinnabarinus,thrips and aphids was tested on greenhouse pepper.The banker plant,flowering marigolds（Tagetes eracta）,was used to establish O.sauteri population.Results showed that O.sauteri could control pests in pepper plants.Five to seven weeks after release,control efficiencies of releasing O.sauteri at rates of 0.5 or 1 per m2 on T.cinnabarinus and thrips ranged from 97.20% to 99.95%.Control efficiency of releasing O.sauteri with 1 per m2 on aphids reached 96.39%,while control efficiency of releasing O.sauteri at rate of 0.5 per m2 on aphids was only 22.78%.The results show that O.sauteri release can control insect pests on greenhouse pepper plants.
