Muscoid dipterous collected from cattle dung pats in pastures in Itumbiara, Goiás, Brazil

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 extraçäo e separaçäo 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

Microimenópteros parasitóides coletados em fezes bovinas em Itumbiara, Goiás / Microhimenopterous parasitoids collected in cattle dung in Itumbiara, Goiás

This work reports the occurrence of microhimenopterous in cattle dung in Itumbiara, Goiás, Brazil. Cattle dung pats were exposed on a pasture for 24, 48, 72, 96, 120, 144, 168, 192, 216 and 240 hours and were then separately taken to the laboratory for artropods extraction. A total of 100 dung pats were exposed at pasture. The pupae were individually placed in transparent gelatin capsules until the emergence of the parasitoids. The main species of parasitoids collected from bovine dung were Paraganapis egeria and Spalangia drosophilae

Primeira ocorrência de Triplasta coxalis (Ashmead) em poupas de Palaeosepsis sp. e nova ocorrência de Kleidotoma nigra (Hartig) (Hymenoptera: Figitidae: Eucoilinae) no Brasil / First ocurrence of Triplasta coxalis (Ashmead) in pupae of Palaeosepsis sp. and new ocurrence of Kleidotoma nigra (Hartig) (Hymenoptera: Figitidae: Eucoilinae) no Brasil

Triplasta coxalis (Ashmeda) (Figitidae: Eucolinae), was found as a parasitoid of Palaeosepsis sp. (Diptera: Sepsidae) in Itumbiara, GO, Brazil (18§25'S and 49§13'W). The samples of bovine dung were taken from pats 24, 36, 72, 96, 120, 144, 168, 192, 216 and 240 hours of exposittion, placed in plastic containers and kept in the laboratory conditions. The pupae were extracted by flotation in water. Pupae were individually placed in gelatin capsules until emergence of adult flies or their parasitoids. Four and one specimes of Triplasma coxalis and Kleidotoma nigra, respectively, were collected. This was the first report on occurrence of the parasitoid Kleidotoma nigra and Triplasta coxalis in Goiás

Dípteros muscóides associados com fezes bovinas e seus parasitóides em Goiás / Muscoid dipterous insects associated with cattle feces and their parasitoids in Goiás State, Brazil

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 per cent), Sarcophagula occidua Fabricius (51.5 per cent) (flies), Pachycrepoideus vindemiae (Rondani) (28.0 per cent) and Paraganaspis egeria Diaz & Gallardo (29.3 per cent)
