[Advances of the study of sarcosaphagous insects in forensic medicine].

The study of sarcosaphagous insects is a subspecialty in forensic medicine based on the knowledge of entomology. It could help to determine the time of death, especially the postmortem interval in decomposed cases. This paper explores its history, species and erosion process of sarcosaphagous insects. It reviews the species identifying methods with molecular biology and entomological morphology. Details of its application in estimating postmortem interval in recent years and study of sarcosaphagous insects in the field of forensic medicine are summarized.
