Parasitoides de Ornidia obesa Fabricius (Diptera: Syrphidae) coletados em fezes de galinha no Brasil / Parasitoids of Ornidia obesa Fabricius (Diptera: Syrphidae) collected in chicken feces in Brazil
This study reports the occurrence of Pachycrepoideus vindemmiae (Rondani) (Hymenoptera Pteromalidae) and Spalangia cameroni Perkins (Hymenoptera Pteromalidae) as parasitoids of Ornidia obesa Fabricius (Diptera Syrphidae) in poultryfarms in Morrinhos, Goiás, stateBrazil. Samples of chickenfeces were collected at two weeks intervals and taken to the laboratory. The pupae were extracted by waterflotation. Each pupa was placed in capsules of gelatin until the emergence of dipterous or their parasitoids. The parasitism percentage of P. vindemmiae and S. cameroni was 5.1 percent.(AU)
