This study had the objective of verifying the frequency of microhymenopterous Eucoilinae (Hymenoptera: Figitidae) parasitizing dipterous species developing in cattle dung, in Panamá, Goiás State, from May to December 2003. The hosts pupae were obtained by the flotation method and individually placed in gelatin capsules until the emergency of the adult flies or their parasitoids. The frequencies of parasitism by Kleidotoma nigra (HARTIG, 1840), Paraganaspis egeria (DÍAZ, GALLARDO and WALSH, 1996), Triplasta atrocoxalis (ASHMEAD, 1895) and Triplasta coxalis (ASHMEAD, 1895) were 6.45%, 3.33%, 3.33% and 13.33%, respectively.
