This work was carried out in a poultry house (Granja Capuavinha), Monte Mor, State of São Paulo, from February 1991 to April 1992 with the purpose of studying the synanthropic flies and their parasitoids. The pupae were extrated from manure using a water-flotation method. Berlese-Tullgren's funnel was used to extract parasitoids and fly larvae. Each pupa was kept in a small transparent glass vial for 35 days until the emergence of the fly or parasitoid. After this period, the pupae that did not yield adult flies or parasitoids were dissected. The following species of fly were collected: Chrysomya putoria (Wiedeman), Muscina stabulans (Fallén), Musca domestica L., Fannia pusio (Stein). In addition several species of Sepsidae were also collected. The following species of parasitoids that emerged from fly pupae were collected: Spalangia gemina (Boucek), S. cameroni (Perkins), Muscidifurax raptoroides Kogan & Legner, Pachycrepoideus vindemiae (Rondani), Nasonia vitripennis (Walker) and Trichopria sp. (Diapriidae). Tachinaephagus zealandicus (Ashmead) (Encyrtidae) a larval pupal parasitoid also ocurred. This is the first report of Trichopria sp., a gregarious parasitoid, attacking pupae of C. putoria. About 13% of parasitoids did not eclode successfuly from the parasitoid pupae which may indicate a recent association between Trichopria sp. and C. putoria in Brazil.
