The aim of the current study was to analyze two major pitfalls in forensic entomological casework: delayed evidence sampling and the effect of low-temperature storage of the body. For this purpose, temperature profiles of heavily infested corpses during cooling and cases in which insect evidence was collected both at the scene and during autopsy were evaluated with regard to species composition and development stages found. The results show that the temperature in the body bags remained at higher average temperatures up to 10 °C relative to the mortuary cooler, therefore, sufficient for larval development, with significant differences in temperature between larval aggregations on one and the same body. In addition, we found large differences both in species number, species composition, and the developmental stages found at the scene and during the autopsy. These data and observations underscore the importance of sampling evidence at the scene and recording temperatures throughout the cooling period of a body.
证据采样延迟和尸体低温储存的影响。为此，评估了重度感染尸体在冷却过程中的温度曲线，以及在现场和尸检时收集昆虫证据的案例，以确定发现的物种组成和发育阶段。结果表明，相对于太平间冷却器，尸袋内的温度平均高出10°C，足以支持幼虫发育，同一具尸体上幼虫聚集处的温度存在显著差异。此外，我们发现在现场和尸检时发现的物种数量、物种组成和发育阶段都存在很大差异。这些数据和观察结果强调了在现场采集证据以及记录尸体整个冷却期温度的重要性。
