摘要

准确估计尸检间隔(PMI)对于成功调查可疑死亡至关重要。法医学指标对PMI估计的准确性至关重要。为了研究三个不同季节(即雨季、冬季和夏季)温度波动下不同阶段的时间持续时间,在实验室条件下饲养了大头金蝇和小头金蝇。在实验室中,在雨季、冬季和夏季的温度波动条件下,大头金芽虫的活动时间分别为237小时47分钟、263小时51分钟和211小时13分钟。而在雨季、冬季和夏季,若虫期分别为239小时14分钟、286小时02分钟和216小时26分钟。这项研究表明,法医调查人员必须从昆虫的发育过程中考虑到这些变量中的每一个,才能更准确地估计PMI。

Studies on Time Duration of Life Stages of Chrysomya megacephala andChrysomya rufifacies (Diptera: Calliphoridae) during Different Seasons
Accurate estimation of post mortem interval (PMI) can be crucial to the successful investigation of suspicious death. The forensic indicator blowflies are essential for accuracy in estimation of PMI. The Calliphoridae species Chrysomya megacephala and Chrysomya rufifacies were reared in laboratory condition for studying their time duration of different stages under the fluctuating temperature in three different seasons (i.e. rainy season, winter season and summer season). In laboratory, at the fluctuating temperature during rainy season, winter season and summer season, Chrysomya megacephala took 237 hours 47 minutes, 263 hours 51 minutes and 211 hours 13 minutes respectively. Whereas the Chrysomya rufifacies took 239 hours 14 minutes, 286 hours 02 minutes and 216 hours 26 minutes during rainy season, winter season and summer season respectively. This study shows that forensic investigators will have to take each of these variables into consideration from the development of insects in order to give a more accurate estimate of PMI.
