The minimum postmortem interval can be estimated based on knowledge of the pattern of insect succession on a corpse. To use this approach requires that we take into account the rates of insect development associated with particular climatological conditions of the region. This study is the first to look at insect succession on decomposing carcasses in the high altitude plains (Paramo) in Colombia, at 3035 m above sea level. Five stages of decomposition were designated with indicator species identified for each stage: Callíphora nigribasis at the fresh stage; Compsomyiops verena at the bloated stage; Compsomyiops boliviana during active decay; Stearibia nigriceps and Hydrotaea sp. during advanced decay and Leptocera sp. for dry remains. A succession table is presented for carrion-associated species of the region, which can be used for estimating time since death in similar areas. Compsomyiops boliviana is reported for the first time in Colombia.
可以根据对尸体上昆虫演替模式的了解来估计最短死后间隔时间。要采用这种方法，我们需要考虑与该地区特定气候条件相关的昆虫发育速率。本研究首次观察了哥伦比亚海拔3035米的高海拔平原（帕拉莫）上正在分解的尸体上的昆虫演替情况。确定了分解的五个阶段，并为每个阶段确定了指示物种：新鲜阶段为黑基丽蝇；肿胀阶段为韦氏嗜尸蝇；活跃腐烂阶段为玻利维亚嗜尸蝇；高度腐烂阶段为黑尾扁角蝇和水蝇属；干燥残骸阶段为瘦角蝇属。列出了该地区与腐肉相关物种的演替表，可用于估计类似地区的死亡时间。玻利维亚嗜尸蝇在哥伦比亚首次被报道。
