Abstract

Cadaverous entomofauna successions vary according to the region, environment, and climate, and such differences may occur within the same country due to seasonal variations. The present study aimed to analyze and compare the dipterofauna that visit or colonize carcasses in the urban and coastal areas of São Paulo, Brazil, during summer and winter seasons. Four swine (Sus scrofa Linné, 1758) carcasses of approximately 12 kg were used. The animals were previously euthanized and then placed in metal cages covered with a flight intercept trap (Shannon, modified). In total, 10,495 flies from 39 families were collected, with 15 species belonging to the Calliphoridae family, 14 species belonging to the Fanniidae family, 43 species belonging to the Muscidae family, and 22 species belonging to the Sarcophagidae family. Flies from these four families visited all carcasses; however, they did not show the highest visitation frequencies in all of the trials. Species variations occurred between the experiments that were performed at different locations and in different seasons. Furthermore, difference in the number of insects attracted to each stage of decomposition was observed. In addition to the four families highlighted above, the families Phoridae, Sepsidae, Otitidae, and Piophilidae were observed in all carcasses.
