摘要： 目的 研究成都市嗜尸昆虫种类及其与季节变化的关系。方法 经过两年重复试验,观察3～11月兔尸上嗜尸昆虫种类变化。结果 发现3～11月兔尸上出现的嗜尸昆虫种类主要有舍蝇、丝光绿蝇、大头金蝇、赭尾麻蝇、巨阿尾丽蝇。其中,巨阿尾丽蝇见于3、4月,舍蝇出现于4月中旬至10月初,而大头金蝇、丝光绿蝇、赭尾麻蝇则自3月至10月中下旬均可见到,10月底以后则见不到任何嗜尸苍蝇。幼虫的出现晚于成虫1～4天不等,与季节及环境有关。结论 通过舍蝇、丝光绿蝇、大头金蝇、赭尾麻绳、巨阿尾丽蝇的生命周期的研究,有望为成都市法医学实践中死亡时间的推断提供依据。

Abstract: Objective To study the species of sarcosaphagous insects. Methods Rabbits were killed and placed outdoors from March to November. Flies that appeared the cadavers were observed and identified. Results There are five main flies,ie,Muscadomesticauicina,Lucilia sericata,C.Megacephala,S.fuscicauda,Aldrichiragrahormi. From midtime of April to the beginning of October,Muscadomesticauicina could be seen on the cadvers,however,Aldrichiragrahormi only could be seen before the beginning of May. Otherwise ,Lucilia sericata,C.Megacephala,S.fuscicauda could be seen on the cadvers from March to the end of October. After the midtime of November,none of sarcosaphagous flies could be seen on the cadvers. On the other hand,maggots of sarcosaphagous flies could be seen often on the cadvers after adults of sarcosaphagous flies intruding 1 to 4 days,relating to tempreture of environment. Conclusion If these flies history of life be studied,it is useful for estimating postmortem interval in Chengdu.
