Forensic entomology is the science that uses insects and other arthropods associated with animal carcasses under decomposition, seeking relevant information to the body, such as location, cause or time of death. Among the insects of forensic interest, the flies are usually the first and most abundant to colonize a carcass. This study aimed to analyze what are the patterns of decomposition, for Sus scrofa, according to a execution of artificial body perforations, aimed the correlation whit forensic sciences, since they cause injury and hemorrhage in the tissues, caused mainly by sidearms, or white weapons. Where used a total of six pigs, three for the winter season and three for the summer, in which, for each season, one of the pigs had no perforations (Control), another had an abdominal perforation measuring about 15cm (P1) and a third pig featuring five abdominal perforations (P5), measuring about 3cm each one. For visual analysis of the effect of these perforations in the decomposition process, in each situation, thermal and digital photos were taken daily, as well as special thermal dataloggers (TidBITS) were placed in various parts of carcasses, to measure the average daily temperatures during the decomposition process. Diptera adults where collected daily in this decomposition sites, aiming to get a check-list of the insects of the order Diptera who visited the carcasses in the period of the experiment, for each season, winter and summer. The results reveals that occurs a significant differences between each treatment for each season: the greater is the number of abdominal perforations, greater is the quantity of decaying flies and the speed of attraction to the substrate too, accelerating, therefore, the decomposition process. Regarding the differences between the two seasons, the decomposition is about four times faster in the summer, a fact that can be understood by the amount of flies collected in this station had been infinitely ...
