摘　　要：对竹广肩小蜂和竹长尾小蜂的产卵习性、虫瘿生成能力、不同类型虫瘿的产生过程和消长动态的研究表明，竹广肩小蜂产卵于竹株换叶后，新萌生小枝（芽）的基部节间内，刺激寄主使被产卵部位组织增生膜大形成虫瘦；竹长尾小蜂必须产卵于竹广肩小蜂已形成的虫瘿中，幼虫孵化后杀死竹广肩小蜂幼虫，占居虫瘿，继续取食虫痞内壁组织完成其生活史。因此，竹长尾小蜂是寄食于竹广肩小蜂虫瘿内的，故该虫并非竹子害虫，而是竹广肩小蜂的天敌昆虫。Egg-laying habit, gall-making ability, larval behaviour and species quantita-tive dynamics of the eurytomid wasp, Aiolomorphous rhopaloides and the torymid, Diomorusaiolomorphi,were observed for identifing the interspecific relationship of the two species.A.rhopaloides lays eggs in newly-sprouted buds and a gall develops at the site of egg-laying asthe bud develops into a new branchlet.D. aiolomorphi lays eggs in the young gall developedby A. rhopaloides and its larvae kill the eurytomid larvae,occupy the gall and feed on the in-ternal tissue before maturing. It is suggested,based on the results,that the torymid,insteadof a pest insect of bamboo,can be regarded as a natural enerny of A. rhopaloides.
