Several studies have investigated palm trees’ microbiota infected with red palm weevil (RPW) (Rhynchophorus ferrugineus), the major pest of palm trees. This study compared the microbial communities of infected and uninfected palm trees in the Hail region, Northern Saudi Arabia, determined by high-throughput 16S rRNA gene sequencing by Illumina MiSeq. The results indicated that taxonomic diversity variation was higher for infected tree trunk than the healthy tree trunk. Soil samples from the vicinity of healthy and infected trees did not have a significant variation in bacterial diversity. Myxococcota, Acidobacteriota, and Firmicutes were the dominant phyla in RPW-infected tree trunk, and Pseudomonadaceae was the most prominent family. This study is the first report on the characterization of RPW-infected and healthy palm trees’ microbiome.

几项研究调查了棕榈树的微生物群被红棕象甲 (RPW) ( Rhynchophorus ferrugineus )感染，红棕象甲是棕榈树的主要害虫。本研究比较了沙特阿拉伯北部 Hail 地区受感染和未受感染棕榈树的微生物群落，由 Illumina MiSeq 的高通量 16S rRNA 基因测序确定。结果表明，感染树干的分类多样性变异高于健康树干。来自健康和受感染树木附近的土壤样本在细菌多样性方面没有显着变化。粘球菌属、酸杆菌属和厚壁菌门是 RPW 感染的树干中的优势门，假单胞菌科是最突出的科。这项研究是关于 RPW 感染和健康棕榈树微生物组特征的第一份报告。
