Control Efficiencies of Releasing Orius sauteri (Heteroptera:Anthocoridae) on Some Pests in Greenhouse Pepper

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.
