Insect succession on three rabbit carcasses placed 110.49 cm above ground in winter in Riyadh City, Saudi Arabia was examined in three different microhabitats: dry, semi-submerged, and submerged in tap water. The complete decomposition of the carcasses took 20 d and included five stages. In total 715 insects collected from carrion in different microhabitats were identified morphological, followed by the partial sequence confirmation of their 16S rRNA mitochondrial genes. Results showed that the insect species found and species richness differed among microhabitats. Carrion placed in the dry microhabitat showed the highest species richness and colonized by 400 insect specimens belonging to 16 species. Carrion placed in the semi-submerged microhabitat contained 271 insect specimens belonging to 12 species, showing a relatively low species richness. Lastly, the submerged microhabitat showed the lowest species richness, as the carrion placed in it attracted only 44 insects belonging to 9 species.
在沙特阿拉伯利雅得市，将三具放置在离地面 110.49 厘米高处的兔尸放置在三个不同的微生境中进行研究：干燥、半淹没和淹没在自来水中。在完全分解兔尸的过程中，共经历了五个阶段，用时 20 天。总共从不同微生境的腐肉中收集到 715 种昆虫，并对其 16S rRNA 线粒体基因进行了部分序列确认。结果表明，不同微生境中的昆虫种类和丰富度存在差异。放置在干燥微生境中的腐肉表现出最高的物种丰富度，有 400 个昆虫标本属于 16 个物种。放置在半淹没微生境中的腐肉包含 271 个昆虫标本，属于 12 个物种，物种丰富度相对较低。最后，淹没微生境的物种丰富度最低，因为放置在其中的腐肉仅吸引了 44 只属于 9 个物种的昆虫。
