RESUMO
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 poultry farms in Morrinhos, Goiás, state Brazil. Samples of chicken feces were collected at two weeks intervals and taken to the laboratory. The pupae were extracted by water flotation. 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)

RESUMO
This study reports, for the first time, the occurrence of Spalangia cameroni Perkins (Hymenoptera: Pteromalidae) as parasitoid of Ornidia obesa Fabricius (Diptera: Syrphidae) in poultry farms in Morrinhos, Goiás, Brazil. Manure chicken samples, collected at two weeks intervals, were taken to the laboratory and the pupae were extracted by water flotation. Each pupa was placed in capsules of gelatin until the emergence of dipterous or their parasitoids. The parasitism percentage was 9.5%.
Este estudo relata a primeira ocorrência de Spalangia cameroni Perkins (Hymenoptera: Pteromalidae) como parasitóide de Ornidia obesa Fabricius (Diptera: Syrphidae) encontrado em granjas de aves poedeiras em Morrrinhos, Goiás, Brasil. Amostras de fezes de galinha foram coletadas em intervalos de duas semanas de sua exposição, levadas para o laboratório para extração das pupas pelo método de flotação. As pupas foram individualizadas em cápsulas de gelatina e mantidas até a emergência dos dípteros e/ou parasitóides. A porcentagem de parasitismo foi de 9,5%.
RESUMO
This study reports, for the first time, the occurrence of Eurytoma sp. (Hymenoptera: Pteromalidae) as parasitoid of Fannia pusio (Wiedemann) (Diptera: Fanniidae) found in chicken dung in Itumbiara, Goiás, Brazil. Manure samples, collected at two weeks intervals, were taken to the laboratory and the pupae were extracted by water flotation. Each pupa was placed in capsules of colorless gelatin until the emergence of dipterous or their parasitoids. The parasitism was 1.3 percent(AU)

ABSTRACT This study reports, for the first time, the occurrence of Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) as a parasitoid of Ornidia obesa Fabricius (Diptera: Syrphidae) found in chicken dung in Itumbiara, Goiás, Brazil. Manure samples, collected at 2-week intervals, were taken to the laboratory and the pupae were extracted by water flotation. Each pupa was placed in capsules of colorless gelatin until the emergence of flies or their parasitoids. The parasitism percentage was 9%.
RESUMO Este estudo relata a primeira ocorrência de Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) como parasitóide de Ornidia obesa Fabricius (Diptera: Syrphidae) encontrado em fezes de galinhas em Itumbiara, Goiás, Brasil. Amostras de fezes foram coletadas em intervalos de duas semanas de sua exposição, levadas para o laboratório para extração das pupas pelo método de flutuação. As pupas foram individualizadas em cápsulas de gelatina e mantidas até a emergência dos dípteros e/ou parasitóides. A porcentagem de parasitismo foi de 9%.
