The rabbit carcasses used in this study were buried at depths of 20 and 40 cm, were examined to construct a fly succession database on buried carrion in Riyadh, Saudi Arabia. Twenty-four rabbits were buried, 12 at 20 cm and 12 at 40 cm. One carcass at each depth was exhumed at 10-day intervals up to 120 days. The degradation rate varied among the carcasses. Differences in species and their colonization were also found in the superficial and exhumed carcasses. Eleven species of flies were recorded on carcasses interred at a depth of 20 cm and seven species at 40 cm, while 13 species were recorded on the carcasses over the top of the soil. Species sp (Diptera: Calliphoridae), Thomson, and (Wiedemann) (Diptera: Sarcophagidae) were dominant at both depths, while (Wiedeman), (Macquart) (Diptera: Calliphoridae), Linnaeus, and Wiedemann (Diptera: Muscidae) were dominant in surface carcasses. (Loew) ((Diptera: Phoridae) is a common and typical forensic indicator that was found in the decay/advanced decay and dry stages at a depth of 20 cm. These findings are possibly useful in forensic investigations involving buried bodies in Riyadh, Saudi Arabia.
本研究中使用的兔尸体被埋在20厘米和40厘米深处，对其进行检查以构建沙特阿拉伯利雅得掩埋腐肉的蝇类演替数据库。共掩埋了24只兔子，12只埋在20厘米深处，12只埋在40厘米深处。在每个深度，每隔10天挖出一具尸体，直至120天。尸体的降解率各不相同。在表层和挖出的尸体上还发现了蝇类物种及其定殖的差异。在埋于20厘米深处的尸体上记录到11种蝇类，40厘米深处记录到7种，而在土壤表面的尸体上记录到13种。丝光绿蝇（双翅目：丽蝇科）、汤氏绿蝇和贝氏麻蝇（双翅目：麻蝇科）在两个深度均占主导地位，而巨尾阿丽蝇（维德曼）、大头金蝇（马夸特）（双翅目：丽蝇科）、家蝇（林奈）和厩腐蝇（维德曼）（双翅目：蝇科）在表层尸体中占主导地位。蚤蝇（洛伊）（双翅目：蚤蝇科）是一种常见且典型的法医指示物种，在20厘米深处的腐烂/高度腐烂和干燥阶段被发现。这些发现可能对沙特阿拉伯利雅得涉及掩埋尸体的法医调查有用。
