Microhimenópteros parasitóides de dípteros muscóides coletados em diferentes substratos em área de mata em Itumbiara, Goiás / Microhimenopterous parasitoids of muscoids dipterous collected from different substrata in a wood area in Itumbiara, Goias, Brazil

This paper reports the occurrence of parasitoids in pupae of flies (Diptera) collected from several different substrata in Itumbiara, Goiás, Brazil. The pupae were isolated by flotation. They were individually placed into gelatin capsules and kept until the emergency of adult flies or their parasitoids. From March 2001 through April 2002, a total of 684 parasitoids and 830 pupae of flies were collected from humans feces, chicken viscera, fish, and bovine kidney. Brachymeria podagrica were identified in a high number of samples. The prevalence of parasitism was of 82.4 percent.

Ocorrência de Brachymeria podagrica (Fabricius) (Hymenoptera: Chalcididae) como parasitóide de dípteros coletados em diferentes substratos em Itumbiara, Sul de Goiás, Brasil / Occurrence of Brachymeria podagrica (Fabricius) (Hymenoptera: Chalcididae) as parasitoid of díptera collected in different substrata in Itumbiara, South of Goiás, Brazil

This work aimed to study the prevalence of parasitism of the parasitoid Brachymeria podagrica in Itumbiara, Goiás, using five different substrata: cattle kidneys, human feces, viscera of chicken, fish and cattle liver. The pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergency of the adult flies or their parasitoids. The prevalence of parasitism was of 13.8 percent

Aphaereta sp. (Hymenoptera: Braconidae: Alysiinae) as a natural enemy to Peckia chrysostoma (Wiedemann) (Diptera: Sarcophagidae), in Brazil

This paper reports the first occurence of the parasite Aphaereta sp. (Hymenoptera: Braconidae: Alysiinae) which wascollected from Peckia chrysostoma pupae (Diptera: Sarcophagidae) by means of traps containing some fish baits in a wood area close to the Agronomy college (Faculdade of Agronomia) in Itumbiara, Goiás, in the period from March to September, 2001. A total of 362 gregarious specimens of parasitoids from 26 pupae of P. chrysostoma. Aphaereta sp. was collected, with several individuals emerging from the same pupae

Pachycrepoideus vindemiae Rondani (Hymenoptera: Pteromalidae) as parasitoid of Diptera, in Brazil

Este estudo determinou as espécies de hospedeiros do parasitóide Pachycrepoideusvindemiae Rondani (Hymenoptera: Pteromalidae) em fezes humanas, rins e fígado de bovino, peixe e frutos. As pupas, obtidas pelo método de flutuaçäo, foram colocadas individualmente em cápsulas de gelatina e mantidas até a emergência das moscas e/ou parasitóides. A prevalência total de parasitismo foi de 15,7 por cento. Este trabalho registra a primeira ocorrência de Pachycrepoideusvindemiae em pupas de Peckiachrysostoma

Brachymeria podagrica (Fabricius) (Hymenoptera: Chalcididae) as a parasitoid of Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae): first report in Brazil

Este trabalho relata a primeira ocorrência do parasitóide Brachymeria podagrica (Fabricius, 1787) parasitando estádios imaturos de Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae) no Brasil. Utilizaram-se armadilhas contendo como isca vísceras de galinha. As pupas foram obtidas pelo método de flutuaçäo. Elas foram colocadas individualmente em cápsulas de gelatina e mantidas até a emergência das moscas e/ou dos parasitóides. Foram obtidas 29 pupas de C. albiceps, quatro das quais emergiram parasitóides. A prevalência de parasitismo foi de 13,7 por cento
