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，猪胴体在室外地面上的分解过程可分为5个连续的阶段，第1、2、3、4、5、6、7、8、10、11、12、13、14、16、17、18、19、20、21、22、23、24、28、29、e.新鲜、膨胀、腐烂、干燥和残留阶段。在猪尸体上发现了3目19科33种常见昆虫。其中，以无氏阿丽蝇、丝光绿蝇、巴氏绿蝇、大头金蝇和粗须副实蝇为优势种。在猪胴体腐解过程中，昆虫群落具有明显的时间演替特征。各虫群的出现时间与猪胴体的腐烂程度有明显的相关性。这一相关性可作为法医学推断死亡时间的依据。
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.
