摘　　要：【目的】寻找东亚小花蝽Orius sauteri规模化饲养的饲料来源。【方法】用腐食酪螨、朱砂叶螨和桃蚜在17.5、22.5、27.5℃,RH70%下饲养东亚小花蝽,并组建生命表。【结果】腐食酪螨饲养的东亚小花蝽若虫70%-80%能发育为成虫,与桃蚜饲养没有显著差异,但显著高于朱砂叶螨饲养的(低于50%);在17.5℃下,该猎物饲养的东亚小花蝽没有产卵,净生殖率Ro为0,用朱砂叶螨和桃蚜饲养时其净生殖率Ro分别为1.18和1.09;在22.5℃时用腐食酪螨、朱砂叶螨和桃蚜饲养的东亚小花蝽的净生殖率Ro分别为12.86、15.93和6.11,三种猎物均可完成小花蝽的世代增殖;在27.5℃时用腐食酪螨、朱砂叶螨和桃蚜饲养的东亚小花蝽的净生殖率Ro分别为0.88、3.02和21.70,腐食酪螨饲养的东亚小花蝽的内禀增长率为负数。【结论】腐食酪螨可以作为东亚小花蝽若虫阶段的规模化饲养的饲料。[Objective] The objective of the study is try to find a new diet on rearing of Orius sauteri massively. [Method] O. sauteri was reared by Tyrophagus putrescentiae, Tetranytrus cinnabarinus or Brevicoryne brassicae as preys at 17.5 ℃, 22.5 ℃, 27.5℃, respectively, and its life tables were made in laboratory. [Result] The results revealed that more than 70% of O. sauteri nymphs were developed to adults when they fed on T putrescenti, which was no significant difference compared to those fed on B.brassica, but was significantly higher than those fed on T. cinnabarinus （survival rates〈 50%）. At 17.5℃, O. sauteri reared with T. putrescentiae had no oviposition. The net reproduction rate （Ro） of O.sauteri reared with T. cinnabarinus and B. brassicae at 17.5℃ were 1.18 and 1.09, respectively. The Ro of O. sauteri reared with T. putrescentiae, T. cinnabarinus and B. brassicae were 12.86, 15.93,6.11 at 22.5℃ and 0.88, 3.02,21.70 at 27.5℃, respectively. At 27.5℃, the intrinsic rate of natural increase （rm） was negative as O.sauteri reared with T. putrescentiae. [ Conclusion] These results indicate that T. putrescentiae can be used to rear O. sauteri nymphae massively.
