摘　　要：竹广肩小蜂和竹长尾小蜂是竹林瘿小蜂类的优势种。研究表明广肩小蜂１ａ一代，以蛹在虫瘿内越冬：成虫２月中旬至４月中旬羽化，３月下旬至４月下旬出瘿，产卵于萌动小枝芽基部的节间内并形成虫瘿，在虫瘿内完成卵、幼虫和蛹的发育；幼虫发生期４月上旬～９月中旬，５龄，以虫瘿内壁组织为食。长尾小蜂１ａ一代，以幼虫在虫瘿内越冬；成虫于４月中旬至５月上旬羽化、出瘿，产卵于已被广肩小蜂产卵的芽中；幼虫孵化后占据广肩小蜂的虫瘿，幼龄时可食广肩小蜂幼虫虫体，但以植食为主；幼虫５龄，发生期５月上旬至次年３月下旬，１１月后渐渐老熟、越冬。he eurytomid wasp,Aiolomorphous rhopaloldes and the torymid,Diomorusaiolomorphi, are two dominant species of chalcid-flies infesting bamboo. Adults of A.rhopaloides emerge from mid February to mid April, but stay in the gall until late March.They lay eggs in newly-sprouted buds and a gall develops at the site of egg-layiiig as the buddevelops into a new branchlet.1～3 eggs can be laid in each hud but only one larva survives.The larvae feed on internal tissue of the gall and pupate in mid September. Winter is passedas pupae in the gall and there is one generation a year. D. aiolomorphi pupate from early Jan-uary to mid March.Adults emerge in late April and lay eggs in young galls developed by A.rhopaloides.Larvae of D. aiolomorphi,after hatching,kill the larvae of A. rhopaloides,occu-py the gall,feed on the internal tissue and develop into maturity after November. The to-rymid overwinters as mature larvae in the gall.There is one generation a year.
