RESUMO

The decomposition of animal carcasses occurs, in addition to other factors, through the action of necrophagous insects. Six blowfly species Lucilia eximia (Wiedemann, 1819), Chrysomya albiceps (Wiedemann, 1819), Chrysomya megacephala (Fabricius, 1794), Chrysomya putoria (Wiedemann, 1819), Cochliomyia macellaria (Fabricius, 1775), (Diptera: Calliphoridae) and Patonella intermutans (Thomson, 1869) (Diptera: Sarcophagidae) are considered the most important carrion-breeders in Campinas-SP, Southeastem Brazil. This work determined the growth curves, deveIopmental times for egg, larva and pupa, and fecundity and mortality rates for the species reared at 13, 17, 20, 25, 28 31 and 35°C. AlI experiments were done in growth chambers with constant photoperiod and humidity. Larvas were fed artificial insect culture medium and were weighed at 6, 12 or 24 hour intervals, dependig on the age. The results showed that the temperature had significant influence in alI aspects studed. The interval between, 25 oC and 28°C, was found to be the best for the development of these species. At 13°C did occured eclosion of the eggs, and at the 35°C the time of deveIopment was reduced. However it was observed a rate ofmortality high, and a low number of eggs by female. This resulted are basic subsidies for the application ofthe Forensic Entomology in Brazil.
