| 摘 要： | 多食性天敌对其猎物植物系统的选择是其重要生物学特性之一,决定了对不同猎物控制的有效性。东亚小花蝽Orius sauteri是西花蓟马Frankliniella occidentalis(Pergande)及二斑叶螨Tetranychus urticae的重要捕食性天敌。本文在温室笼罩条件下通过释放东亚小花蝽,而后在不同时间调查其在西花蓟马和/或二斑叶螨危害2d后的豆株及健株上的数量,研究了其定位反应。结果表明:东亚小花蝽显著趋向西花蓟马及由西花蓟马与二斑叶螨同时危害的豆株,而较少趋向二斑叶螨单独危害的豆株及健株。在各处理豆株上,东亚小花蝽的日活动规律中,傍晚时分有离开植株的趋势。

| Abstract: | Orius sauteri （Hemiptera：Anthocoridae） is one of the natural enemies of the western flower thrip （WFT） and two-spotted spider mite （TSSM）.In this article the orientation of O.sauteri to healthy bean plants,and those damaged by WFTs and/or TSSMs,was studied in small cages under greenhouse conditions of 26℃±1℃,RH：70%.The results show that plants that had been damaged by WFTs,or by both Wfts and TSSMs,attracted many more predatory bugs than either undamaged plants or those damaged by TSSMs alone.O.sauteri tended to leave both healthy and damaged plants at dusk （18：30 pm）. |
