摘要腐尸上昆虫区系及其发育演替模式的研究，对于促进昆虫证据在法医科学中的应用，特别是对估计死后时间间隔（PMI）具有重要意义。动物尸体分解和节肢动物演替受多种因素影响，并表现出明显的区域差异；因此，需要在不同生物地理区域进行详细的演替研究，以了解昆虫在不同环境下的演替模式。本研究于2021年夏季在中国西北宁夏石嘴山市野外使用3头家猪（苏斯scrofa domestica L., 1758）尸体进行。共收集到尸食性昆虫40种，隶属于3目16科。双翅目中丝光绿蝇（Meigen,1826）、大头金蝇（fabicius,1794）和雷金蝇（Meigen,1826）为优势种（双翅目：金蝇科）。鞘翅目在尸体分解过程中，优势种由半针孔棘足棘（Saprinus semipunctatus, Fabricius,1792）（鞘翅目：毛蝇科）转变为斑纹棘足棘（Dermestes maculatus DeGeer,1774）和frischii Kugelann，1792（鞘翅目：皮蝇科）。在高温低湿的极端条件下，尸体迅速干燥，进入残体阶段，之后大量的尸体干组织吸引了鞘翅目，尤其是皮蛾类的种群，这些种群数量丰富，一直持续到第50天实验结束。本研究首次对西北地区的演替进行了法医昆虫学调查，为该地区夏季PMI的估算提供了基础数据。
Abstract The study of insect fauna and their development and succession patterns on decaying cadavers is crucial to promoting insect evidence as a useful tool in forensic science, particularly for estimating the postmortem interval (PMI). Body decomposition and arthropod succession are affected by many factors and exhibit substantial regional variations; therefore, detailed succession studies in different biogeographic regions are required for understanding the successional patterns of insects in various environments. This study was conducted in the summer of 2021 using three domestic pig carcasses (Sus scrofa domestica L., 1758) in the field of Shizuishan City, Ningxia, Northwest China. A total of 40 species of necrophagous insects belonging to three orders and 16 families were collected. Among Diptera, Lucilia sericata (Meigen,1826), Chrysomya megacephala (Fabricius,1794), and Phormia regina (Meigen,1826) (Diptera: Calliphoridae) were the dominant species. As for Coleoptera, the dominant species changed throughout the process of carcass decomposition from Saprinus semipunctatus (Fabricius,1792) (Coleoptera: Histeridae) to Dermestes maculatus DeGeer,1774 and Dermestes frischii Kugelann,1792 (Coleoptera: Dermestidae).The carcasses desiccated rapidly and reached the remains stage under extreme conditions of high temperatures and low humidity, after which a large amount of dried tissue of the carcasses attracted populations of Coleoptera, particularly Dermstidae, which were abundant and remained until the end of the experiment on day 50. The current study is the first forensic entomological investigation of succession in Northwest China and provides basic data for the estimation of PMI during summer in this region.
