Hyalomma tick species are considered the competent vector tick species that carry and transmit Crimean-Congo hemorrhagic fever virus (CCHFV) to humans and animals. Hyalomma asiaticum is one of the major tick species widespread in the Xinjiang Uygur Autonomous Region (XUAR) of China. To determine the potential prevalence of H. asiaticum in XUAR, species distribution modeling was performed using MaxEnt algorithm assembled with bioclimatic variables and curated tick presence records. The results indicate that potential habitats of H. asiaticum mainly cover the northern and western XUAR. The suitable habitats included the west rim of the Taklimakan Desert, Turpan Basin, and Junggar Basin. The models show a mean area under the curve of 0.865 ± 0.068 for H. asiaticum based on 10-fold cross-validation. Despite limited tick presence records used in the study, this work describes the potential distribution and the association of important bioclimatic variables that are crucial for the survival of H. asiaticum in many arid areas in XUAR. The model could be helpful in tick distribution study and surveillance of CCHFV in the region.
壁虱物种被认为是有能力携带和传播克里米亚-刚果出血热病毒（CCHFV）给人类和动物的媒介壁虱物种。亚洲璃眼蜱是广泛分布在中国新疆维吾尔自治区（XUAR）的主要壁虱物种之一。为了确定 XUAR 中亚洲璃眼蜱的潜在流行情况，使用 MaxEnt 算法结合生物气候变量和已整理的壁虱存在记录进行了物种分布模型构建。结果表明，亚洲璃眼蜱的潜在栖息地主要覆盖 XUAR 的北部和西部。适宜的栖息地包括塔克拉玛干沙漠西缘、吐鲁番盆地和准噶尔盆地。该模型在 10 倍交叉验证的基础上，基于 0.865±0.068 的曲线下面积表示亚洲璃眼蜱的表现。尽管研究中使用的壁虱存在记录有限，但这项工作描述了重要生物气候变量的潜在分布和关联，这些变量对亚洲璃眼蜱在 XUAR 许多干旱地区的生存至关重要。该模型有助于该地区的蜱分布研究和 CCHFV 的监测。
