Spalangia nigroaenea Curtis, 1839 ( Hymenoptera: Pteromalidae ) como inimigo natural de dípteros coletados em fezes bovinas no sul do Estado de Goiás / Spalangia nigroaenea Curtis, 1839 ( Hymenoptera: Pteromalidae ) as natural enemy of muscoid dipterous collected in cattle dung in south of Goiás State, Brazil

From January 1998 to February 2001, 53 specimens of Spalangia nigroaenea Curtis, 1839 (Hymenoptera: Pteromalidae) were collected in 7,203 pupae of flies in cattle dung in Cachoeira Dourada and Itumbiara, GO, Brazil. The samples were collected and taken to the laboratory for pupae extraction by water flotation technique. The pupae were individually placed in transparent gelatin capsules until the emergence of the adult flies or their parasitoids. The percentage of parasitism was 0.74%.(AU)

Dípteros muscóides associados com carcaça de suíno e seus parasitóides em área de pastagem e de mata em Goiás

Muscoid dipterous insects associated with pig carcass and their parasitoids collected in pasture and wood were collected from savanna (cerrado) at Goiás, Brazil. The species collected more often were: Chrysomya albiceps (89.5%), Ophyra sp. (6.9%) (flies) and Pachycrepoideus vindemiae (33.3%) and Spalangia endius (38.8%) (parasitoids). The parasitism rate was 0.4%.

Dípteros muscóides de importância médica e veterinária e seus parasitóides em Goiás

The objective of this work was to identify flies of medical and veterinary importance and their natural enemies, located around the city of Itumbiara, GO, Brazil. Five thousand eight hundred and twenty-five muscoid dipterous insects and parasitoids were collected from a Brazilian savanna (cerrado) area of Itumbiara. Substrates for obtaining flies were liver. The most frequent fly and parasitoid species found were: Fannia pusio (29.2%) and Atherigona orientalis (26.8%) (flies), Nasonia vitripennis (56.0%) and Brachymeria sp. (26.6%) (parasitoids). Musca domestica was the dipterous species of greatest sanitary importance collected. This is the first report of the species Brachymeria sp. and Hememcyrtus sp. in the State of Goias. Data contribute to the knowledge of dipterous and parasitoids fauna in the state of Goias.

Dípteros muscóides associados com fezes bovinas e seus parasitóides em Goiás

A total number of 8779 pupae of Diptera were collected in stables in the municipal district of Itumbiara, GO, Brazil, from June to December 1999. The principal fly and parasitoid species found were Musca domestica L. (38.4%), Sarcophagula occidua Fabricius (51.5%) (flies), Pachycrepoideus vindemiae (Rondani) (28.0%) and Paraganaspis egeria Diaz & Gallardo (29.3%).

Espécies de Spalangia (Hymenoptera: Pteromalidae: Spalanginae) em fezes bovinas como parasitóides pupais de dípteros muscóides em Goiás

Species of parasitoids of dung-breeding Diptera were collected at a range pasture in Itumbiara, GO, Brazil. The samples of bovine dung, approximately seven and eight day-old, were collected and carried to the laboratory and the pupae were extracted by water flotation. The pupae were individually placed in transparent gelatin capsules until the emergence of the adult flies or their parasitoids. Spalangia drosophilae (40.8%) Ashmead and Spalangia nigroaenea (35.6%) were the predominant species that parasitized pupae of dipterous muscoids. The rate of parasitism was 3.8%.

Paraganspis egeria Díaz, Gallardo & Walsh (Hymenoptera: Figitidae: Eucoilinae) as potential agent in the biocontrol of muscoid dipterous collected in several substracts in Itumbiara, Goias, Brazil

Este estudo determinou as espécies de hospedeiros do parasitóide Paraganspis egeria (Díaz, Gallardo & Walsh, 1996) (Hymenoptera: Figitidae) em esterco bovino, fezes humanas, rins de bovino, galinha e carcaça de suíno. 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 prevalência total de parasitismo foi de 3,4%.

Muscoid dipterous collected from cattle dung pats in pastures in Itumbiara, Goiás, Brazil / Dípteros muscóides coletados de fezes bovinas em pastagens em Itumbiara, Goiás

A coleta de Diptera em fezes bovinas depositadas nas pastagens foi conduzida de janeiro a agosto de 2001 em Itumbiara, Goiás. As fezes foram expostas nas pastagens por 24, 48, 72, 96, 120, 144, 168, 192, 216 e 240 horas e posteriormente levadas para laboratório para extração e separação dos dípteros. Um total de 100 fezes bovinas foram expostas nas pastagens, das quais 3099 dípteros muscóides foram coletados. As espécies mais abundantes foram: Palaeosepsis spp. e Sarcophagula occidua. A maioria dos exemplares foi coletada em fezes bovinas expostas nos períodos de 72 e 144 horas no campo.(AU)
