摘　　要：对杭州地区猪尸体的腐败过程及尸体上昆虫群落的演替规律 ,进行了初步观察和研究。结果表明 ,室外地表上猪尸体的腐败过程可以划分为新鲜、肿胀、腐烂、干化和残骸 5个连续的阶段 ;常见昆虫包括 3目、 19科、 33种 ,其中双翅目的巨尾阿丽蝇、丝光绿蝇、南岭绿蝇、大头金蝇、肥须亚麻蝇等为优势种。尸体上昆虫群落的演替有明显的时间规律可循。许多昆虫类群的出现时间与尸体腐败阶段有明确的对应关系 ,这种对应关系可以为法医科学中推测死后间隔时间(postmorteminterval,PMI)提供依据。A preliminary study on the decomposition and insect community succession of pig carcase was carried out in Hangzhou District. The results showed that the decomposition of pig carcase put on outdoor ground could be distinguished into 5 continuous stages, i. e. fresh, bloated, decayed, dried and remains stages. Thirty three common insect species of 19 families from 3 orders were found on the pig carcases. Among them, Aldrichina grahami, Lucilia sericata, Lucilia bazini, Chrysomya megacephala, and Parasarcophaga crassipalpis were the dominant ones. A distinct time related succession of insect community was observed during the decomposing of pig carcase. There was a distinct correlation between the appearing time of many insect groups and the decomposition stage of pig carcase. This correlation might be used as a foundation for the estimation of postmortem interval in forensic medicine.
