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。

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.
