摘要棘水蚤是一种尸食性物种，广泛分布于东亚和澳大拉西亚地区。考虑到该物种摄食后的幼虫或幼虫在身体的腐烂后期甚至骨骼阶段仍然大量存在，它可以作为估计最小死后间隔(PMImin)的一个很好的补充指标。这也可能扩大PMImin的范围，当主要殖民者不再与身体有关或作为成年人出现时。在16~34℃的7个恒温范围内，研究了刺突小蜂的发育历期、积累度小时数和幼虫体长的变化，建立了3种估算PMimin的发育模型，包括同构图、等长图和温度总和模型。在16℃、19℃、22℃、25℃、28℃、31℃和34℃条件下，棘突圆头蛾从卵到成虫的发育历期分别为1,412.6±62.9,867.4±14.9,657.1±22.9,532.3±10.1,418.8±21.3,379.8±16.6和340.0±20.3h。发育下限L 0℃为10.50±0.2℃，积温常数K为7648.83±146.74度小时。通过回归分析，得到了不同温度下仔鱼孵化后体长随时间变化的方程。本研究为法医学鉴定中PMimin的检测提供了基础数据。
Abstract Hydrotaea spinigera Stein is a necrophagous species, widely distributed in Oriental and Australasian regions. Considering that the postfeeding larvae or puparia of this species can still be found in abundance at the advanced decomposition stage or even the skeleton stage of remains, it can serve as a good supplementary indicator for estimating the minimum postmortem interval (PMImin). This could also extend the range of PMImin when the primary colonizers are no longer associated with the corpse or have emerged as adults. This study investigated the development duration, accumulated degree hours, and larval body length changes of H. spinigera at seven constant temperatures ranging from 16 to 34°C, and established three development models for estimating PMImin, including isomorphen diagram, isomegalen diagram, and thermal summation model. At 16, 19, 22, 25, 28, 31, and 34°C, the development durations of H. spinigera from egg to adult stage were 1,412.6 ± 62.9, 867.4 ± 14.9, 657.1 ± 22.9, 532.3 ± 10.1, 418.8 ± 21.3, 379.8 ± 16.6, and 340.0 ± 20.3 h, respectively. The lower developmental threshold L 0 was estimated as 10.50 ± 0.20°C, and the thermal summation constant K was 7,648.83 ± 146.74 degree hours. Using regression analysis, equations were obtained modeling the change of larval body length with time after hatching at different temperatures. This study provided basic data based on the growth and development of H. spinigera for the estimation of PMImin in forensic science.
