RESUMO
The aim of this study is to report the first occurrence of the parasitoid Triplasta coxalis (Ashmead, 1865) (Hymenoptera: Figitidae: Eucoilinae) in pupae of Archisepsis scabra (Loew, 1861) (Diptera: Sepsidae) in cattle dung in Brazil. The experiment was carried out in Monte Alegre, MG. One obtained the pupae through the flotation method. They were individually placed in gelatin capsules until the emergence of the adult dipterous or their parasitoids. Fourty seven pupae of A. scabra were obtained, two of which yielded the parasitoid T. coxalis. The percentage of parasitism was 4.3 percent.
Objetivou-se, no presente trabalho, relatar a primeira ocorrência do parasitóide Triplasta coxalis (Ashmead, 1865) (Hymenoptera: Figitidae: Eucoilinae) como inimigo natural de Archisepsis scabra (Loew, 1861) (Diptera: Sepsidae) em fezes bovinas no Brasil. O experimento foi realizado em Monte Alegre, MG. As pupas foram separadas pelo método de flutuação e individualizadas em cápsulas de gelatina onde foram mantidas até a emergência dos dípteros e/ou dos parasitóides. Obtiveram-se 47 pupas de A. scabra, das quais emergiram dois parasitóides pertencentes à espécie T. coxalis. A porcentagem de parasitismo foi de 4,3 por cento.
RESUMO
Triplasta coxalis (Ashmeda) (Figitidae: Eucoilinae), was found as a parasitoid of Palaeosepsis sp. (Diptera: Sepsidae) in Itumbiara, GO, Brazil (18º25'S and 49º13'W). The samples of bovine dung were taken from pats 24, 36, 72, 96, 120, 144, 168, 192, 216, and 240 hours of exposition, 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 specimens of Triplasta coxalis and Kleidotoma nigra, respectively, were collected. This was the first report on occurrence of the parasitoid Kleidotoma nigra and Triplasta coxalis in Goiás.
