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)

This study determined the species of microhymenopterous of Diptera present in cattle and buffalo dung, from May 2003 to June 2004 and from April 2006 to March 2007 in chicken manure. All samples were collected in Southern Goiás State, Brazil. The dipterous pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of the flies and/or their parasitoids. The percentages of parasitism in cattle dung and chicken manure were 12.4% and 10.0%, respectively.(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%.

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)

The species of parasitoids associated with Musca domestica L. (Diptera: Muscidae) collected in human feces, cattle liver, chicken viscera, cattle dung, chicken manure and food leftovers in Itumbiara, State of Goiás, Brazil, from July 1999 to July 2003, were studied. The pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of the adult flies or their parasitoids. The overall prevalence of parasitism was 0.7%. The most frequent species was Pachycrepoideus vindemiae (Rondani) (Hymenoptera: Pteromalidae), accounting for 35.4%.(AU)

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%.
