摘　　要：初步调查了安徽芜湖稻田害虫的小蜂总科寄生蜂种类、多样性指数和均匀度.结果显示,共采集了小蜂714只,隶属于9科、28属、34种,其中安徽新纪录科1个,安徽新纪录属16个,安徽新纪录种21种;多样性指数最高的是赤眼蜂科为1.31,其次是金小蜂科和缨小蜂科,分别为1.20和1.14;均匀度指数最高的是旋小蜂科为0.99,其余较低;以金小蜂科的物种最为丰富,而数量上以赤眼蜂科最多.稻螟赤眼蜂、褐腰赤眼蜂和赤带扁股小蜂是值得开发利用的本地寄生蜂资源.An investigation was carried out on the parasitic chalcidoids community in paddy fields in Wuhu, and the diversity characteristics were analyzed. The results showed that 714 specimens were collected, belonging to 9 families, 28 genera and 34 species, including 1 newly recorded family in Anhui, 16 newly recorded genera in Anhui, and 21 newly recorded species in Anhui. Among the nine families, the highest diversity index was Trichogrammatidae （1.31）, and the second Pteromalidae （1.20）, then Mymaridae （1.14）. The highest evenness index was Eupdmidae （0.99）, and the rests were low. Pteromalidae had the richest species, while Trichogrammatidae had the highest specimen quantity. Trichogramma japonicum, Paracentrobia andoi and Elasmus cnaphalocrocis are local parasitic ehaleidoids resources worthy to he developed and used.
