摘要上颌Creophilus maxillosus（L.，1758）是在尸体上发现的一种常见且分布广泛的甲虫物种，其发育持续时间远远长于属于丽蝇科和麻蝇科的物种。因此，C.上颌肌可作为估计最小死后间隔时间（PMImin）的辅助指标，并可在原代定植者不再与尸体接触或已从脓液中出来时大大扩展PMImin的范围。更好地描述了C。上颌肌的发展需要应用这个物种的法医调查。本研究对C.在17.5-32.5 °C范围内的七个恒定温度下对上颌肌进行了研究。通过回归分析，得到了仔鱼出壳后体长随时间变化的模拟方程。绘制了特定温度下幼虫体长随时间变化的等长图和特定温度下不同发育里程碑持续时间的等形图。此外，还建立了不同发育阶段的积温模型和整个发育过程。通过回归分析，估算了发育起点温度（D 0）和热累积常数（K），得到了上颌骨的发育起点温度（D 0）。这些结果为法医调查提供了重要的工具，以根据C.上颌骨
Abstract Creophilus maxillosus (L., 1758) is a common and widely distributed beetle species found on corpses, and its development duration is far longer than species belonging to the genus Calliphoridae and Sarcophagidae. Therefore, C. maxillosus can be used as a supplementary indicator to estimate minimum postmortem interval (PMImin), and could greatly extend the range of PMImin when the primary colonizers are no longer associated with the corpse or have emerged from pupae. Better descriptions of C. maxillosus development are needed to apply this species for forensic investigations. In this study, the development of C. maxillosus at seven constant temperatures ranging from 17.5–32.5 °C was studied. Through regression analyses, the simulation equations of larval body length variation with time after hatching were obtained. Isomegalen diagrams of the changes of larval body length over time at specific temperatures, and the isomorphen diagrams on the duration of different developmental milestones at specific temperatures were generated. In addition, thermal summation models of different developmental stages and the overall development process of C. maxillosus were generated through regression analysis, by estimating the development threshold temperatures (D0) and the thermal summation constants (K). These results provide important tools for forensic investigations to generate a long-range of PMImin estimation based on the development of C. maxillosus.
