The presence of insects on human cadavers has potential judicial value in medicolegal cases. This research emphasized the important role of insects in postmortem decomposition. It was conducted to investigate the composition and abundance of insects from human corpses during autopsies in legal medicine. It was implemented in the city of Shiraz, south Iran. Insects associated with human corpses were carefully collected and put into labelled vials. They were then identified using valid taxonomic keys. Fifteen outdoor (67%) and indoor discovered cadavers were examined. All but one was covered at the time of discovery. From these several species of entomofauna played important roles in the minimum postmortem interval (minPMI) estimate. Insects included the orders of Diptera and Coleoptera. Overall, 14 different species of arthropods were identified. Within Diptera, 2 families of Sarcophagidae and Calliphoridae were present in 73% of the cases with Calliphora vicina Robineau-Desvoidy and Chrysomya albiceps Wiedemann accounting for about half of the cases. The latter family members, Calliphoridae, were more frequently (52%) collected in autumn and winter. Only 4/15 outdoor cadavers had beetles. Four species of Coleopterans; namely Dermestes frischii Kugelann, Nitidula flavomaculata Rossi, Creophilus maxillosus Linnaeus and Saprinus chalcites Illiger; were recorded for the first time from 3 corpses in Iran. The presence and diversity of different insects on human corpses could contribute to the advancement of forensic entomology knowledge and the refined estimates of minPMI in medicolegal cases.
人体尸体上昆虫的存在在法医学案件中具有潜在的司法价值。本研究强调了昆虫在尸体分解过程中的重要作用。该研究旨在调查法医学尸检期间人体尸体上昆虫的组成和数量。研究在伊朗南部设拉子市开展。与人体尸体相关的昆虫被仔细收集并放入贴有标签的小瓶中。然后使用有效的分类学关键特征对它们进行鉴定。共检查了15具室外（67%）和室内发现的尸体。除一具尸体外，其他尸体在被发现时均有覆盖物。从这些尸体上发现的几种昆虫在最短死后间隔（minPMI）估计中发挥了重要作用。涉及的昆虫目包括双翅目和鞘翅目。总体而言，共鉴定出14种不同的节肢动物。在双翅目中，麻蝇科和丽蝇科的2个科出现在73%的案例中，其中红头丽蝇和白头金蝇约占一半。后者丽蝇科的成员在秋季和冬季更为频繁地（52%）被采集到。15具室外尸体中只有4具发现有甲虫。四种鞘翅目昆虫，即弗里奇皮蠹、黄斑露尾甲、大隐翅虫和铜绿扁隐翅虫，首次在伊朗的3具尸体上被记录到。人体尸体上不同昆虫的存在和多样性有助于推进法医昆虫学知识，并在法医学案件中更精确地估计minPMI。
