Dípteros sinantrópicos associados a restos alimentares e seus parasitóides

Abstract

This study was carried out in order to determine the species of parasitoids associated with Diptera collected in food remains. Pupae of Diptera were collected twice a month from the food remains kept for more than fifteen days in garbage containers. Pupae were obtained by flotation and they were placed individually in gelatin capsules until the emergence of the adult flies or parasitoids. The most frequent species was Megaselia sp. with 47.1%. The overall percentage of parasitism was 2.4% and in Musca domestica L. the parasitism rate reached 20.0%. Pachycrepoideus vindemiae (Rondani), and Muscidifurax raptor Girault & Sanders presented parasitism rates of 2.1% and 0.2%, respectively.
