Postmortem interval estimation based on Chrysomya albiceps (Diptera, Calliphoridae) in a forensic case in the Andean Amazon, Caquetá, Colombia

ABSTRACT This is the first application of forensic entomology in a case involving a human corpse found in the urban area of the Municipality of Florencia, Caquetá, Colombia, in the Piedemont of the Colombian Amazon. Three days after removing the body from the scene, pupae and puparia were collected and identified as Chrysomya albiceps (Wiedemann, 1819) (Diptera, Calliphoridae). The postmortem interval was estimated on the basis of previously published data and verified through accumulated degree hours (ADH) and intrapuparial development. The estimated minimum postmortem interval was of 229 hours (9.5 days).

摘要
本研究首次将法医昆虫学（forensic entomology）应用于哥伦比亚卡克塔省佛罗伦萨市城区（地处哥伦比亚亚马孙山麓地带）发现的一具人体尸体相关案件中。在从现场移走尸体三天后，研究人员采集了蛹（pupa）及蛹壳（puparium），经鉴定为白额绿蝇（Chrysomya albiceps，Wiedemann, 1819）（双翅目（Diptera），丽蝇科（Calliphoridae））。本研究基于已发表的文献数据估算了死后间隔时间（postmortem interval, PMI），并通过积温小时数（accumulated degree hours, ADH）以及蛹内发育情况进行了验证。最终估算得到的最小死后间隔时间为229小时（合9.5天）。
