A main objective of the study is the establishment of a forensic entomological database for Riyadh, Saudi Arabia. Decomposition processes and beetle succession were analysed on rabbit carcasses in three different habitats (agricultural, desert and urban) in the period from May to July 2014. Due to the effects of the high temperature at the study sites, carrion reached the dry stage within 12 days in the agricultural habitat, and 6 days in the desert and urban habitats. A total of 125 beetles belonging to eight species and five families were collected during the decaying process, with their abundances increasing from the fresh to decay stages. The prevailing species belonged to the families of Dermestidae and Histeridae. It was not possible to confirm any definitive relationship between the occurrence of a single species and a particular stage of decomposition. The beetle communities were also not distinctively different between desert and urban habitats, but a distinct community was evident in the agriculture habitat. In addition, there were distinct beetle communities between the decay stage and the other stages. The dry stage recorded the lowest number of beetles. This study indicated that, the habitat type had an effect on the decay process and the abundance rate of the beetles.
该研究的一个主要目标是为沙特阿拉伯利雅得建立一个法医昆虫学数据库。2014年5月至7月期间，在三种不同栖息地（农业、沙漠和城市）的兔子尸体上分析了分解过程和甲虫演替情况。由于研究地点高温的影响，农业栖息地的腐肉在12天内达到干燥阶段，沙漠和城市栖息地则为6天。在腐烂过程中，共收集到属于8个物种、5个科的125只甲虫，其数量从新鲜阶段到腐烂阶段逐渐增加。优势物种属于皮蠹科和阎甲科。无法确定单一物种的出现与特定分解阶段之间的任何明确关系。沙漠和城市栖息地的甲虫群落也没有明显差异，但农业栖息地有明显不同的群落。此外，腐烂阶段与其他阶段之间存在明显不同的甲虫群落。干燥阶段记录到的甲虫数量最少。这项研究表明，栖息地类型对腐烂过程和甲虫的丰度率有影响。
