摘要: 为了明确对于凶杀案件中死亡时间判断有重要意义的蝇蛹的形态随时间的变化规律,在16、20、24、28、32℃饲养了巨尾阿丽蝇并定期取样、解剖,显微镜下观察其体表形态变化。结果表明:巨尾阿丽蝇蛹壳内蛹呈现出规律性的变化,这些规律性的变化可指示出蛹的发育进程,进而可指示该昆虫在尸体上出现的时间,从而对死者的死亡时间做出判断。根据这些规律性的变化可将蛹期划分为7个阶段。不同恒温下达到以上阶段所需时间不同,高温下短而低温下长。

Abstract: The forensically important fly Aldrichina grahami (Aldrich) was reared at constant temperature to study the chronology of parate adults within puparia. The results show that some morphological changes within the puparium can be used as age markers. The pupal stage of Aldrichina grahami can bedivided into seven developmental stages. The time required for pupal development was inversely proportional to temperature.
