摘要： 目的 检验嗜尸性昆虫推断死亡时间的可行性及准确度，为鉴定实践提供参考。 方法 筛选11例已破案证实且昆虫学证据比较完整的案件，对案件中出现的昆虫种类、推断结果及真实结果进行统计和对比分析。 结果 案发现场所发现的昆虫包括大头金蝇、绯颜裸金蝇、乌足锡蝇、丝光绿蝇、厚环黑蝇、厩腐蝇、麻蝇（未鉴定具体种类）、蛆症异蚤蝇、黑水虻、丽腐阎甲、大隐翅甲、白腹皮蠹和赤颈郭公甲共13种。11例案件死亡时间均落在推断的时间范围内，其中72.73%的案件推断结果及真实结果在同一天。 结论 嗜尸性昆虫可以简单方便地推断死亡时间，死亡时间在蝇类或甲虫发育一代时间内的案件，推断结果比较准确，超过此范围，准确度降低。

Abstract: Objective To test the feasibility and accuracy of with sarcosaprophagous insects postmortem interval （PMI） estimation with sarcosaprophagous insects and provide references for estimation practice. Methods Eleven cases confirmed by the detection results, with complete entomological evidence were selected. The insect species, estimation results and true results involved in the cases were statistically analyzed and compared. Results Thirteen species of insects were found at the criminal scene, including Chrysomya megacephala （Fabricius）, Chrysomya rufifacies （Macquart）, Chrysomya nigripes （Aubertin）, Lucilia sericata （Meigen）, Hydrotaea spinigera Stein, Muscina stabulans （Fallén）, Sarcophagid （species were not identified）, Megaselia scalaris （Loew）, Hermetia illucens （Linnaeus）, Saprinus splendens （Paykull）, Creophilus maxillosus （Linnaeus）, Dermestes maculatus （De Geer） and Necrobia ruficollis （Fabricius）. The PMI of all eleven cases was within the range of estimated PMI. The estimated results of 72.73% cases were on the same day of the true results. Conclusion Sarcosaprophagous insects can estimate the PMI simply and conveniently. In cases where the PMI is within the time range of one generation of flies or beetles, the estimation results are relatively accurate. However, the estimation is less accurate when the PMI is beyond the time range.
