摘　　要：法医昆虫学是近年来法庭科学中发展较快的学科之一,而利用昆虫学证据来推断死亡时间或称死后经历时间(PMI)是其最主要的应用。当尸体PMI达一周以上,无法通过蝇蛆生长发育历期来推算时,仍可以借助嗜尸性昆虫群落演替规律来判断。嗜尸性昆虫群落演替规律与尸体腐败过程息息相关,法医昆虫学家通过对尸体腐败进行人为分期,能够辨别出不同的演替波次,从而达到推断PMI的目的。本文对嗜尸性昆虫群落演替研究与应用进行了综述,并分析了未来研究趋势,希望能为相关研究和实践应用提供参考。Forensic entomology,which is one discipline of forensic science,progressed vary fast in s in recent years. Using entomological evidences to estimate the postmortem interval（ the time of death,PMI） is its main application. If the real PMI of body was longer than a week,insect fauna succession could be used to estimate the PMI instead of development duration of fly larvae. Insect fauna succession pattern is closely related to the progress of decomposition. Forensic entomologists could identify different succession waves to estimate the PMI by staging the progress of decomposition. This paper demonstrated researches on insect fauna succession and its implication. It also analyzed the future research trends with providing some references for research and practice in this field.
