The blowfly Lucilia cuprina is a primary colonizer of decaying vertebrate carrion, and its development provides a temperature-dependent clock that may be used to estimate the post-mortem interval of corpses and carcasses in medicolegal forensic investigations. This study uses the development of L. cuprina raised on a substrate of chicken liver at six constant temperatures from 18 to 33 °C to calibrate a thermal accumulation model of development for forensic applications. Development was optimal near 24 °C; above this temperature, survival of post-feeding life stages was increasingly compromised, while below it, development was increasingly retarded. The lower developmental threshold (~12 °C) and thermal summation constants of L. cuprina are distinct from those reported for Lucilia sericata, verifying that it is essential to identify African Lucilia specimens accurately when using them to estimate post-mortem intervals.
绿蝇 Lucilia cuprina 是腐尸的主要定殖者，其发育过程提供了一个依赖温度的时钟，可用于法医学调查中估计尸体和 carcasses 的死后间隔时间。本研究利用在 18 至 33 °C 的六个恒定温度下以鸡肝为底物饲养的 Lucilia cuprina 的发育情况，校准用于法医应用的发育热积累模型。发育在 24 °C 左右时最佳；高于此温度，取食后生命阶段的存活率越来越低，而低于此温度，发育则越来越迟缓。Lucilia cuprina 的较低发育阈值（约 12 °C）和热积累常数与报道的丝光绿蝇不同，这证实了在使用非洲 Lucilia 标本估计死后间隔时间时准确识别它们至关重要。
