Ecología de una taxocenosis de Calliphoridae del área platense (Provincia de Buenos Aires) (Insecta, Diptera)

Resumen

This paper constitutes the first approach to the knowledge of the ecology of Calliphoridae from Argentina. The selected stüdied area is a rural one located at 34°55’S and 58° W in the suburbs of Villa Elisa, Province of Buenos Aires. Samples were taken hourly from 10.15 am to 4.15 pm, every month from November 1985 to October 1986. Specimens were captured with entomological net while lying on the bait composed by cow meat. The sampling program included shaded and unshaded sites. Air temperature was recorded every hour. Results showed a remarkable heliophily for some of the recorded species. Chrysomya albiceps, Phaenicia sericata, Phaenicia purpurescens and Cochlipmyia macellaria were codominants during spring and summer, while Calliphora vicina and Calliphora nigribasis were so along the winter months. Chrysomya megacephala, Cochliomyia hominivorax,. Compsomyiops fulvierura, Paralucilia fulvinota, Phaenicia eximia, and Sarconesia chlorogaster were poorly represented for most o f the sampling dates. Sex ratio was female biased for the majority of the studied species.
