肉食性甲虫是重要的害虫，但它们也是尸检间隔估计的关键指示昆虫。本文研究了 Necrobia ruficollis (Fabricius, 1775) 在 22 °C 至 34 °C 之间五个恒定温度下的发育情况。估算了幼虫的发育阈值温度和热求和常数，研究了不同龄期幼虫体长与发育时间的关系，以及头囊宽度和尾节距离的关系。研究结果为红颈猪笼草估计最小死后间隔提供了重要的基础发育数据。 Necrobia ruficollis (Fabricius, 1775)（鞘翅目：Cleridae）是一种重要的世界性仓储害虫，也经常出现在高度腐烂和骨骼化的尸体上。它是法医学上重要的物种，预计具有较长的尸检间隔 (PMI)。因此，我们研究了 N. ruficollis 在 22 °C 至 34 °C 之间五个恒定温度下的发育情况。在22、25、28、31和34℃温度下，从卵到成虫的平均发育持续时间（±SD）分别为93.00±1.63、70.67±0.94、65.33±3.40、47.33±0.94和56.66±8.73天。根据发育时间和累积度时结果，生成同构图和热求和模型。通过线性模型估计发育阈温度和积温常数的计算值分别为14.51±0.52℃和684.12±33.85度日。通过非线性模型估计发育下限温度、内在最适温度和致死发育上限温度分别为 14.61、25.90 和 34.94 °C。通过体内测量获得幼虫的形态指标。模拟了生长曲线和发育时间与体长之间关系的方程。此外，通过聚类分析确定了不同龄期幼虫头囊的宽度和尾节之间的距离。通过线性判别分析创建和验证分类器。这些结果为利用红颈猪笼草估计最小死后间隔（最小PMI）提供了重要的基础发育数据。但本研究仅在恒温条件下进行，这些数据在变温条件下的适用性有待进一步证实。
Sarcosaprophagous beetles are significant pests, but they are also key indicator insects for postmortem interval estimation. In this paper, the development of Necrobia ruficollis (Fabricius, 1775) at five constant temperatures between 22 °C and 34 °C was investigated. The developmental threshold temperature and thermal summation constant were estimated, the relationship between the larval body length with development time, and the widths of the head capsules and the distance between the urogomphi at different instars were studied. The results provide important basic developmental data for using N. ruficollis to estimate the minimum postmortem interval. Necrobia ruficollis (Fabricius, 1775) (Coleoptera: Cleridae) is an important cosmopolitan storage pest, and also frequently appears on highly decomposed and skeletonized corpses. It is a forensically important species expected to indicate a longer postmortem interval (PMI). Therefore, we investigated the development of N. ruficollis at five constant temperatures between 22 °C and 34 °C. Under temperatures of 22, 25, 28, 31, and 34 °C, the mean (±SD) developmental durations from eggs to adults were 93.00 ± 1.63, 70.67 ± 0.94, 65.33 ± 3.40, 47.33 ± 0.94, and 56.66 ± 8.73 days, respectively. According to the developmental time and accumulated degree hours results, an isomorphen diagram and thermal summation model were generated. The calculated values of developmental threshold temperature and accumulated temperature constant were estimated by a linear model to be 14.51 ± 0.52 °C and 684.12 ± 33.85 degree days, respectively. Lower developmental thresholds, intrinsic optimum temperature, and upper lethal developmental threshold temperature were estimated by a nonlinear model to be 14.61, 25.90, and 34.94 °C. Morphological indexes of larvae were obtained by in vivo measurements. A growth curve and an equation of the relationship between development time and body length were simulated. In addition, the widths of the head capsules and the distance between the urogomphi of larvae at different instars were determined by cluster analysis. Classifiers were created and validated by linear discriminant analysis. These results provide important basic developmental data for using N. ruficollis to estimate the minimum postmortem interval (minimum PMI). However, this study was only conducted under constant temperature, and the applicability of these data to variable temperature conditions needs to be further confirmed.
