<abstract language="eng">This work reports the occurrence of parasitoid Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) parasitizing pupae of flies (Diptera) in different substrata in Itumbiara, Goiás. The pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of flies or their parasitoids. From May 1998 through April 2002, 737 parasitoids were collected in human feces, cattle liver, chicken, fish and cattle kidney. The prevalence of parasitism was 67.8%
