A partially skeletonized human corpse was found in bushes in Selangor, Malaysia in June 2020. Entomological evidence was collected during the autopsy and sent to the Department of Medical Microbiology and Parasitology, Faculty of Medicine, Universiti Teknologi MARA (UiTM) for minimum postmortem interval (PMI) analysis. Standard protocols were applied when processing preserved and live insect specimens of both larval and pupal stages. Entomological evidence revealed that the corpse was colonized by Chrysomya nigripes Aubertin, 1932 (Diptera: Calliphoridae) and Diamesus osculans (Vigors, 1825) (Coleoptera: Silphidae). Chrysomya nigripes was chosen as the PMI indicator as this fly species is an earlier colonizer compared to D. osculans beetle larvae which their presence is the indicative of late stage of decomposition. For the present case, the pupae of C. nigripes were the oldest insect evidence collected and based on the available developmental data, the estimated minimum PMI was established between 9 and 12 days. It is noteworthy to highlight that this is the first record of D. osculans colonization on a human corpse.
2020 年 6 月，在马来西亚雪兰莪州的灌木丛中发现了一具部分 skeletonized 的人类尸体。在尸检过程中收集了昆虫学证据，并将其送往 UiTM 医学微生物学和寄生虫学系进行最小死后间隔（PMI）分析。在处理保存和活体昆虫幼虫和蛹阶段的标本时，应用了标准方案。昆虫学证据表明，尸体被 Chrysomya nigripes Aubertin，1932（双翅目：Calliphoridae）和 Diamesus osculans（Vigors，1825）（鞘翅目：Silphidae）寄生。选择 Chrysomya nigripes 作为 PMI 指标，因为与 D. osculans 甲虫幼虫相比，这种蝇类是更早的殖民者，而后者的存在表明已进入分解的晚期。就目前的情况而言，收集到的最古老的昆虫证据是 C. nigripes 的蛹，根据现有的发育数据，估计最小 PMI 为 9 至 12 天。值得强调的是，这是首次记录到 D. osculans 对人类尸体的寄生。
