摘　　要：刚竹瘿蚊Procystiphorasp.在天津1 a发生1代,以蛹在竹小枝内越冬。成虫出现在4月上旬,产卵于早园竹Phyllostachys propinquaMcClure的新芽中,幼虫孵化后钻蛀取食虫瘿内物质,于10月上旬化蛹。刚竹瘿蚊有1种内寄生天敌:瘿蚊柄腹姬小蜂Pediobiussp.;2种外寄生天敌:刺胫广肩小蜂Eurytoma setigeraMayr和栗瘿旋小蜂Eupelmus urozonusDalman。另有3种伴生昆虫:竹瘿广肩小蜂Aiolomorphus rhopaloidesWalker、纹黄枝瘿金小蜂Homoporus japonicusAshmead和秆蝇金小蜂Gastrancistrussp.。Procystiphora sp. is a new pest phytophagous and harmful to Phyllostachys propinqua. It has one generation a year in Tianjin and overwinters as pupa in the galls in the branchlet. The adult emerges from the gall in early April and lays eggs on the newly sprouted bud. The larva feeds on the internal tissue of the galls and pupates in early October. Three chalcidoid species were found as its natural enemies：Pediobius sp. , a dominant parasitoid, is an endoparasitoid species, Eurytoma setigera Mayr and Eupelmus urozonus Dalman are the ectoparasitoid species. In addition, three chalcidoid species were reared from branchlets of Phyllostachys propinqua, i. e. Aiolomorphus rhopaloides Walker, Homoporus japonicus Ashmead and Gastrancistrus sp.
