Forensic entomology provides a feasible way to estimate postmortem interval (PMI), of which the growth and development of sarcosaprophagous insects is the most widely used indicator in forensic practice. Over the years, forensic entomologists have carried out a large number of studies on the development biology of sarcosaprophagous insects. This paper illustrates the main factors that affect the development of sarcosaprophagous insects, including temperature, humidity, light, food types and poisons. The development indicators of sarcosaprophagous insects were reviewed from the perspectives of morphology, differential gene expression and biochemical characteristics. It is emphasized that future research of development biology on sarcosaprophagous insects should fully absorb and integrate the methods of artificial intelligence and omics, and the research object also needs further expansion in order to establish a more objective and more accurate PMI estimation method.
法医昆虫学为推断死亡时间提供了一条确实可行的途径，其中嗜尸性昆虫的生长发育规律是法医学实践中应用最广泛的指标。多年来，法医昆虫学者已经开展了大量嗜尸性昆虫发育生物学研究。本文从温度、湿度、光照、食物类型及毒物方面对影响嗜尸性昆虫发育的主要因素进行了阐述，从形态学、差异基因表达及生物化学特征角度对嗜尸性昆虫的发育指标进行回顾，强调未来嗜尸性昆虫发育生物学研究应当充分吸纳和融合人工智能和组学的方法，并进一步拓展研究对象，以建立客观性更强、精度更高的死亡时间推断方法。.
