RESUMO

The existence of sarcosaprophagous insects specialIy Calliphoridae and Sarcophagidae families, is known a long time ago, however, the successional pattern of them in carcass only has been studied recently in tropics. The present study was done at "Reserva Mata de Santa Genebra", Southeastern Brazil, and some aspects of succession, diversity, relative abundance of larvae and adult, stages of decomposition, seasonality and species as forensic indicators were taken. Two domestic pigs were used for each season and exposed to sun and shade. The diversity was high in both families, but the entomological sucession wasn t clearly determinated. The calliphorid had predominated than sarcophagid in number of adults colIected and reared on carcass. The sun had colIected more insects and the shade had reared a great number of individuaIs. The abundance ofChrysomya albiceps (Calliphoridae) was higher in alI experiments and this specie was the better explorer of source. The carcass was a protein source to Cochlyomyia macellaria, C. albiceps, C. putoria and Phaenicia eximia, despite Hemilucilia segmentaria had used a carcass to oviposit. The stages of decomposition of carcass were influenced by temperature and precipitation and the putrefation and fermentation were more representatives than others. This work showed that these flies were the principal agents that do the decomposition of carcass, therefore are important to Forensic Entomology. Only two species could be used as forensic indicators in this natural area : H. segmentaria (Calliphoridae) and Pattonella intermutans (Sarcophagidae )
