The frequency of Pteromalidae species found in Diptera pupae that were collected from cattle dung in Panamá, State of Goiás, Brazil, between May and December 2003 was studied. The pupae were obtained by the flotation method and were individually placed in gelatin capsules until the emergence of the adult flies or their parasitoids. The overall percentage of parasitism was 14.7%. The percentage of parasitism presented by the parasitoids Pachycrepoideus vindemmiae (Rondani), Spalangia cameroni Perkins, Spalangia drosophilae Ashmead , Spalangia endius Walker, Spalangia nigra Latrielle and Spalangia nigroaenea Curtis were 1.7%, 1.4%, 2.4%, 0.7%, 2.4% and 6.1%, respectively.
