Carrion breeding insects may be of great utility in crimes briefing. Studies on forensic entomology are restricted to few localities in Brazil and very few of them were done in the cerrado vegetation (a type of Savannah) until now. This work aimed to survey the main species of dipterans associated with the decomposition process of Sus scrofa and the insect succession pattern in carcasses in the Cerrado. The study was carried out in the dry and humid season of the year, in two cerrado vegetation profiles in Uberlândia, MG. Two pig carcasses were placed in each vegetation profile and time period of the year. The decomposition process was slower and insects were more abundant in the dry season. Differences in temperature, air humidity and pluvial precipitation seemed to be the main physical factors responsible for the differences in the time of decomposition of the pig carcasses between the two seasons. Fourteen species of dipterans (59,467 specimens) bred in the decomposing carcasses. Chrysomya albiceps (Wiedemann) was the species more abundantly breed in the two periods. The other species that breed in the carcasses were: C. putoria (Wiedemann), Hemilucilia segmentaria(Fabricius), Lucilia eximia(Wiedemann) (Calliphoridae), Peckia (Pattonella) intermutans(Walker), Peckia (Squamatoides) trivitatta(Curran), Sarcodexia lambens(Wiedemann) (Sarcophagidae), Musca domestica(L.), Ophyra aenescens(Wiedemann), Stomoxys calcitransL. (Muscidae), Fannia pusio(Wiedemann), Fannia sp. (Fanniidae), Hermetia illuscens L. (Stratiomyidae) and Phoridae sp. The Cerrado of this region presents many dipterans potential forensic indicators.
食腐昆虫在犯罪调查中可能具有很大的用途。巴西对法医昆虫学的研究仅限于少数地区，到目前为止，在塞拉多植被（一种稀树草原类型）中进行的研究很少。这项工作旨在调查与野猪分解过程相关的主要双翅目物种以及塞拉多地区尸体上昆虫的演替模式。该研究在一年中的旱季和雨季进行，地点在米纳斯吉拉斯州乌贝兰迪亚市的两个塞拉多植被区域。在每个植被区域和一年中的每个时间段放置了两头猪的尸体。分解过程在旱季较慢，昆虫数量更多。温度、空气湿度和降雨似乎是导致两个季节猪尸体分解时间差异的主要物理因素。在分解的尸体上繁殖的有14种双翅目昆虫（59467个标本）。白纹丽蝇（Wiedemann）是在两个时期繁殖数量最多的物种。在尸体上繁殖的其他物种有：腐臭丽蝇（Wiedemann）、分段嗜绿蝇（Fabricius）、卓越绿蝇（Wiedemann）（丽蝇科）、叉丽蝇（Walker）、三带叉丽蝇（Curran）、兰氏污蝇（Wiedemann）（麻蝇科）、家蝇（L.）、铜绿蝇（Wiedemann）、厩螫蝇（L.）（蝇科）、小粪蝇（Wiedemann）、粪蝇属（粪蝇科）、亮斑扁角水虻（L.）（水虻科）和蚤蝇科物种。该地区的塞拉多有许多双翅目昆虫具有潜在的法医指示作用。
