This study determined the species of hosts of the parasitoid Hemencyrtus herbertii Ashmead (Hymenoptera: Encyrtidae) in human feces, cattle liver and chicken viscera, collected in Itumbiara, Goias. The pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of adult flies or their parasitoids. The overall prevalence of parasitism was 23.7%.

This paper reports the occurrence of parasitoids in pupae of flies (Diptera) collected from several different substrata in Itumbiara, Goiás, Brazil. The pupae were isolated by flotation. They were individually placed into gelatin capsules and kept until the emergency of adult flies or their parasitoids. From March 2001 through April 2002, a total of 684 parasitoids and 830 pupae of flies were collected from humans feces, chicken viscera, fish, and bovine kidney. Brachymeria podagrica were identified in a high number of samples. The prevalence of parasitism was of 82.4%.

Este estudo teve como objetivo determinar as espécies de parasitoides associados com moscas coletadas em vísceras de galinha, em Itumbiara, Goiás. Armadilhas contendo vísceras de galinha como isca foram utilizadas para atrair a moscas. As pupas, obtidas pelo método de flutuação, foram colocadas individualmente em cápsulas de gelatina (nº 00) e mantidas em laboratório até a emergência das moscas e/ou dos parasitoides. A prevalência total de parasitismo foi de 20,0%. Brachymeria podagrica, Hemencyrtus sp. (Hymenoptera: Encyrtidae), Nasonia vitripennis (Hymenoptera: Pteromalidae), Paraganaspis egeria (Díaz, Gallardo & Wash) (Hymenoptera: Figitidae), apresentaram prevalência de parasitismo de 8,9%, 10,8%, 0,9% e 0,3%, respectivamente.

This work aimed to study the prevalence of parasitism of the parasitoid Brachymeria podagrica in Itumbiara, Goiás, using five different substrata: cattle kidneys, human feces, viscera of chicken, fish and cattle liver. The pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergency of the adult flies or their parasitoids. The prevalence of parasitism was of 13.8%.
