Forensic entomology case reports are the product of rapid development in the field, the widespread acceptance of the science and the application of forensic entomological knowledge. In this study, we retrospectively summarized information derived from 307 forensic entomology case reports from 1935 to 2022 from a global perspective. Our checklist of relevant information included insect species, specific indoor or outdoor preferences, preferred temperatures, and stages of body decomposition. Finally, a concept and calculation method for postmortem interval (PMI) estimation accuracy was proposed. There were 232 cases using insect developmental data and 28 cases using succession patterns to estimate PMI. A total of 146 species of insects were involved in the cases, of which 62.3% were Diptera and 37.7% were Coleoptera. Postmortem intervals were estimated from eggs in 4 cases, larvae in 180 cases, pupae in 45 cases, and puparia in 38 cases. The majority of cases were from June to October, and the average number of species mentioned in the cases was more at 15-30 °C. Considering the standardization of application, in the majority of cases, insect evidence was collected by other personnel and sent to forensic entomologists, there was a delay in the sampling, and the scene or meteorological data were directly used without correcting. Our data shows that there are still many shortcomings in the universality and standardization of forensic entomology in its practical application.
法医昆虫学案例报告是该领域快速发展、该学科被广泛接受以及法医昆虫学知识应用的产物。在本研究中，我们从全球视角回顾性总结了1935年至2022年307份法医昆虫学案例报告中的信息。我们的相关信息清单包括昆虫种类、特定的室内或室外偏好、适宜温度以及尸体分解阶段。最后，提出了死后间隔时间（PMI）估计准确性的概念和计算方法。有232个案例使用昆虫发育数据，28个案例使用演替模式来估计PMI。这些案例共涉及146种昆虫，其中双翅目占62.3%，鞘翅目占37.7%。从卵估计死后间隔时间的案例有4个，从幼虫估计的有180个，从蛹估计的有45个，从蛹壳估计的有38个。大多数案例来自6月至10月，案例中提及的物种平均数量在15 - 30°C时更多。考虑到应用的标准化，在大多数案例中，昆虫证据由其他人员收集并送交法医昆虫学家，采样存在延迟，且直接使用现场或气象数据而未进行校正。我们的数据表明，法医昆虫学在实际应用中的普遍性和标准化仍存在许多不足。
