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%.

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%.

Este trabalho relata a primeira ocorrência do parasitóide Brachymeria podagrica (Fabricius, 1787) parasitando estádios imaturos de Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae) no Brasil. Utilizaram-se armadilhas contendo como isca vísceras de galinha. As pupas foram obtidas pelo método de flutuação. Elas foram colocadas individualmente em cápsulas de gelatina e mantidas até a emergência das moscas e/ou dos parasitóides. Foram obtidas 29 pupas de C. albiceps, quatro das quais emergiram parasitóides. A prevalência de parasitismo foi de 13,7%.
