ABSTRACT
This study reports the occurrence of Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) as parasitoid of Cyrtoneurina pararescita (Diptera: Muscidae) (Couri, 1995) in bovine feces obtained in Goiânia, Goiás state, Brazil. Bovine 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 gelatin until the emergence of dipterous or their parasitoids. The parasitism percentage was of 2.4%. This paper reports the first occurrence of N. vitripennis as parasitoid of C. pararescita worldwide.

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.
ABSTRACT
The synanthropic indexes of Diptera parasitoid present in forest, rural, and urban areas were determined in the municipality of Monte Alegre, MG, from March to November 2006. The dipterous pupae were obtained by the flotation method and individually placed in gelatin capsules until the emergence of the dipterous and/or their parasitoids. The synanthropic indexes of parasitoid Kleidotoma nigra (Hartig) (Hymenoptera: Figitidae), Paraganaspis egeria Díaz, Gallardo & Walsh (Hymenoptera: Figitidae), Spalangia cameroni Perkins (Hymenoptera: Pteromalidae), Trichopria sp. (Hymenoptera: Diapriidae), Triplasta atrocoxalis (Ashmead) (Hymenoptera: Figitidae), and Triplasta coxalis (Ashmead) (Hymenoptera: Figitidae) were +0.1, -100, +50, +100, -3, and -100, respectively.

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.

This study reports the first occurrence of Muscidifurax raptorellus (Hymenoptera: Pteromalidae) in Brazil. Chicken manure samples, collected at two-week interval, were taken to the laboratory and the pupae were extracted by the method of flotation. Each pupa was placed in capsules of colorless gelatin until the emergence of dipterous or their parasitoids. In the study, ten pupae of Fannia pusio (Wiedemann, 1830) (Diptera: Fanniidae) were obtained, two of which yielded the parasitoid M. raptorellus . The percentage of parasitism was 5.0 percent.

This study verified the percentage of parasitism and hosts species of the parasitoid Triplasta atrocoxalis (Ashmead) (Hymenoptera: Figitidae: Eucoilinae) in cattle and buffalo dung, collected in the South of Goiás state, Brazil; from January 1998 to June 2004. The pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of adult dipterous or their parasitoids. The percentage of parasitism in cattle and buffalo dung was 2.5 percent percent and 0.1 percent, respectively.

The species of microhimenopterous in pupae of Diptera present in buffalo dung, collected in the municipality of Itumbiara, GO, from May 2003 to June 2004 were determined. The dipterous pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of the dipterous and/or their parasitoids. The overall percentage of parasitism was 5.0 percent. The more frequent species were: Spalangia drosophilae Ashmead (Hymenoptera: Pteromalidae) with 21.5 percent and Paraganaspis egeria Díaz & Gallardo (Hymenoptera: Figitidae) with 16.3 percent

Relatou-se um novo hospedeiro para o parasitóide Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) em fezes bovinas no Brasil. 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 parasitóides. A porcentagem total de parasitismo foi de 12,5 por cento. Este trabalho registra a primeira ocorrência de P. vindemmiae em pupas de Cyrtoneurina pararescita Couri (Diptera: Muscidae) no Brasil.
