目的：根据深圳地区夏季室内外猪尸体上主要嗜尸性昆虫的生长发育和群落演替规律来推断死亡时间（PMI）。方法从2013年5月初到8月初，在深圳市公安局法医检验中心模拟的室内、外场地分别放置成年猪尸体两头，观察尸体腐败的过程和猪尸体上出现主要昆虫的种类，记录猪尸体腐败各阶段的历期，以及主要昆虫在尸体上的群落演替。结果室内、外的猪尸体分别经历了412.5 h和325 h进入白骨化阶段。主要的嗜尸性昆虫，蝇类以大头金蝇、绯颜裸金蝇、星岛金蝇，甲虫类以大隐翅甲、赤颈郭公甲、丽腐阎甲、白腹皮蠹为优势代表性种类。室外猪尸体在较多雨水的影响下，优势蝇群明显产生二代，室内的猪尸体上未见较大规模二代产生。结论深圳地区夏季室内外猪尸体上主要昆虫的群落演替有规律性，7种代表性昆虫及其幼虫整体的活动规律对推断PMI有较大的意义。

Objective To explore the growing development and community succession of main sarcos-aphagous insects on pig carcasses in summer indoor and outdoor environment in Shenzhen area and to estimate the postmortem interval (PMI). Methods From early May to August in 2013, in Forensic Med-ical Examination Center of Shenzhen Public Security Bureau, the main insect species and the decomposi-tion process were observed in two adult pig carcasses of simulative indoor and outdoor environment. The different decomposition stages and the community succession of insects were recorded. Results The indoor and outdoor pig carcasses showed skeleton 412.5 and 325 hours after death, respectively. The main species of flies on pig carcasses were Chrysomya megacephala, Chrysomya rufifacies and Chrysomya chani. The main species of beetles were Crecphilus maxillosus, Necrobia ruficollis, Saprinus splendens and Dermestes maculatu. The dominant species of flies in the outdoor pig carcasses obviously produced the second generations due to the effect of mass rainfall, nor in the indoor pig carcasses. Conclusion There are regular patterns on the community succession of insects on pig carcasses in summer indoor and out-door environment in Shenzhen area. The activity patterns of seven typical insects and their larva show important value for estimating PMI.
