The main objective of this study was to identify potential forensic indicators in the insect fauna associated with pig carrion and the pattern of insect succession during the decomposition process in two environments of a rural area in Uberlândia, State of Minas Gerais, Brazil. The study was conducted at two locations: in a pasture and in a fragment of a semi-deciduous forest (vegetation profile of the Cerrado biome) in two different seasons (rainy and dry) of 2010. The decomposition process was more rapid in the rainy season. More than 32,000 insects belonging to 17 species of 6 families of Diptera and 2 species of Coleoptera bred in the carcasses. The majority of Diptera bred in the first three stages of decomposition. However, Phoridae and Coleoptera bred mainly in the last two stages. The insects bred more abundantly in the pasture and in the humid season. The exceptions were the Fanniidae (Diptera), which bred more abundantly in the forest and the Dermestidae and Cleridae (Coleoptera), which did not demonstrate any preference in terms of environments and were more abundant in the dry season, respectively. Species such as Chrysomya albiceps (Wiedemann), Peckia (Patonella) intermutans (Walker), Necrobia rufipes (De Geer), and Dermestes maculatus (De Geer) may be potential indicators of post-mortem interval. Hemilucilia segmentaria (Fabricius) and Ophyra aenescens (Wiedemann) may be indicators of localization of the natural environment, while Musca domestica Linnaeus may be an indicator of the anthropic environment. The study thus presented many species of potential forensic indicators in rural areas of this region.
本研究的主要目的是确定与猪尸体相关的昆虫群落中的潜在法医指标，以及巴西米纳斯吉拉斯州乌贝兰迪亚市农村地区两个环境中尸体分解过程中的昆虫演替模式。该研究在两个地点进行：一个牧场和一片半落叶林（塞拉多生物群落的植被类型），时间为2010年的两个不同季节（雨季和旱季）。雨季的分解过程更快。超过32000只昆虫在尸体上繁殖，它们属于双翅目6科的17个物种和鞘翅目的2个物种。大多数双翅目昆虫在分解的前三个阶段繁殖。然而，蚤蝇科和鞘翅目昆虫主要在最后两个阶段繁殖。昆虫在牧场和潮湿季节繁殖得更为丰富。例外情况是厕蝇科（双翅目），其在森林中繁殖更为丰富，以及皮蠹科和郭公虫科（鞘翅目），它们在环境方面没有表现出任何偏好，分别在旱季更为丰富。诸如白纹丽蝇（维德曼）、互变别麻蝇（沃克）、红足死甲（德吉尔）和黄斑皮蠹（德吉尔）等物种可能是死后间隔时间的潜在指标。断带黑绿蝇（法布里丘斯）和铜绿蝇（维德曼）可能是自然环境定位的指标，而家蝇（林奈）可能是人为环境的指标。因此，该研究展示了该地区农村地区许多潜在的法医指标物种。
