ABSTRACT
This study reports, for the first time, the occurrence of Triplasta atrocoxalis (Ashmead) (Hymenoptera: Figitidae: Eucoilinae) as a parasitoid of Palaeosepsis spp. (Diptera: Sepsidae) found in buffalo dung in Itumbiara, Goiás, Brazil. Manure samples, collected at two-week intervals, were taken to the laboratory and the pupae were extracted by water flotation. Each pupa was placed in capsules of colorless gelatin until the emergence of flies or their parasitoids. The parasitism prevalence was 2.7%.
