Insect samples found on human corpses can provide the information important to estimating the minimum postmortem interval （PMI）. A female cadaver, found in a deserted factory in Chongqing of China, was confirmed as a homicide case after the forensic investigation and autopsy. Determining the time of death was difficult due to the inconsistent degree of decomposition in different parts of the decedent. The insect specimens found on the cadaver were identified to be （, Macquart） by morphology and mitochondrial DNA sequence analysis. The PMI was estimated to be 452 h, based on the developmental rate of . The PMI was estimated successfully to be almost precise, which provided an important entomological evidence for case investigation and suspect prosecution. In so doing, this highlights the usefulness of entomological evidence of specific species in the geographic area for PMI accurate estimation, especially in the case of advanced decomposed corpses.
在人体尸体上发现的昆虫样本可以提供重要信息，有助于估计最小死后间隔时间（PMI）。在中国重庆的一个废弃工厂发现的一具女尸，经过法医调查和尸检后被确认为凶杀案。由于死者不同部位的分解程度不一致，因此确定死亡时间很困难。通过形态学和线粒体 DNA 序列分析，确定尸体上发现的昆虫标本为（, Macquart）。根据 的发育速度，估计 PMI 为 452 小时。成功地估计了几乎精确的 PMI，为案件调查和嫌疑人起诉提供了重要的昆虫学证据。这样做突出了特定地理区域的昆虫学证据在准确估计 PMI 方面的有用性，特别是在高度分解的尸体的情况下。
