| 在温室内，试验观察了单独释放和组合释放东亚小花蝽Orius sauteri、丽蚜小蜂Encarsia formosa两种天敌对烟粉虱Bemisia tabaci的控制作用。结果显示：与不释放天敌的空白对照相比，单独释放东亚小花蝽处理对烟粉虱卵、若虫均有较好的控制效果；在释放后第1周, 东亚小花蝽处理及东亚小花蝽和丽蚜小蜂组合处理与对照相比对烟粉虱卵和若虫的控制效果分别达到87.1%、89.3% 和73.9%、78.3%, 两周后的控制效果分别为72.7%、6.9% 和64.8%、57.2%；而丽蚜小蜂的处理在释放天敌后第1周和第3周，对卵的控制效果分别为3.5%、80.3%，第3周对若虫的控制效果为75.7%。在相同数量天敌条件下，东亚小花蝽和丽蚜小蜂的组合处理较天敌单独处理对烟粉虱的控制效果好。 |

| The control effect of flower bug Orius sauteri individually and companied with parasitoid Encarsia formosa on whitefly Bemisia tabaci were assessed in the greenhouse The results showed tha the efficiency of controlling eggs and nymphs of B tabaci by individual O sauteri were better, comparing with blank control After releasing one week, O sauteri individually and companied E formosa treatment were applied to control the pest, their effects reached 87.1%, 89.3% for the eggs and 73.9%, 78.3% for the nymphs, respectively And after two weeks, their effect reached 72.7%, 6.9% for eggs and 64.8%, 57.2% for the nymphs, respectively In E formosa treatment, after the releasing one week and three weeks, the control efficiency reached 3.5%, 80.3% for eggs, respectively And after three weeks, the control efficiency reached 75.7% for nymphs According to our observation, O sauteri collaborated with E formosa showed higher control efficiencies than the individual treatments on the same number of predators |
