【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。更多还原

【Abstract】 【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.更多还原
