Abstract
Different species of parasitoids associated with flies collected on human faeces in Itumbiara County, Goias State, Brazil, were identified. Traps of black tin can with baits and sand were used. Fly pupae were obtained, sifted for extraction, and placed individually into gelatin capsules until emergence of adult flies and/ or parasitoids. The preference of species for their host was evaluated by the Chi-square test, at 5.0% probability. The total percentage of parasitism was 21.9%. From March 2001 to April 2002,180 e specimens of parasitoids in 823 pupae of dipterans. Variable numbers of e specimens of 6 different species of 6 different species of parasitoids were obtained from pupae of infested flies: 22 especimens of Gnathopleura quadridentata Wharton (Braconidae), 21 specimens of Brachymeria (Fabricius) Chalcididae), 23 especimens of Hemencyrtus herbertii Asmead (Encortidae), 1 specimen de Paraganaspis egeria Diaz and Gallardo (Eucoilidae), 13 specimens of Nasonia vitripennis (Walker) and 100 specimens of Pachycrepoideus vindemiae (Rondani) (Pteromalidae). The total percentages of parasitism for Gnathopleura quadridentata, Brachymeria podagrica, Hemencyrtus herbertii, Paraganaspis egeria, Nasonia vitripennis and Pachycrepoideus vindemiae were 2.7%, 2.5%, 2.8%, 0.1%, 1.5%, and 12.1%, respectively. This is the first report on the occurrence of brachymeria podagrica (Fabricius) parasitizing pupae of Ophyra sp. In Brazil.
