We report a forensic entomology case associated with human myiasis in Chiang Mai Province, northern Thailand. The remains of a 53-yr-old-male were concurrently infested with third instars of the two blow fly species, Chrysomya megacephala (F.) and Chrysomya rufifacies (Macquart), near a severe tumor lesion presented on the lower right leg. The presence of third instars, approximately 5 d old, on the day following postmortem indicated that myiasis occurred before death. This is the first report of both fly species acting as a myiasis-producing agent in Thailand. Unsynchronized data between the age of fly larvae due to myiasis premortem and verified age/ condition of the corpse suggest a potential complication and error in the estimation of postmortem interval if other predisposition fly infestations are not considered.
我们报告了泰国北部清迈府一起与人类蝇蛆病相关的法医昆虫学案例。一名53岁男性遗体的右下腿严重肿瘤病变附近，同时寄生有大头金蝇（Chrysomya megacephala (F.)）和红尾肉蝇（Chrysomya rufifacies (Macquart)）的三龄幼虫。死后次日发现约5日龄的三龄幼虫，表明蝇蛆病在死亡前就已发生。这是这两种苍蝇在泰国作为致蝇蛆病媒介的首次报告。由于生前蝇蛆病导致的蝇幼虫年龄与尸体经核实的年龄/状况之间的数据不同步，表明如果不考虑其他易引发苍蝇寄生的因素，在估计死后间隔时可能会出现潜在的复杂性和误差。
