Abstract:
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.
