Therefore , changes in compositions and levels of several biochemical substances , including cuticular hydrocarbon , pteridine , protein and uric acid during growth and development of some common species of necrophagous flies were measured and analyzed , and then the potential of using change patterns in those biochemical substances as age indicators in necrophagous flies was discussed 为此，本文特对不同种尸食性蝇类生长发育过程中表皮碳氢化合物、蝶啶、血淋巴可溶性蛋白和尿酸等的变化规律进行了较系统的测定分析，进而分析了这些变化规律用于幼虫、蛹或成虫日龄推断的可行性及推断方法。
