Camel farming remains a part of the culture of the Arabian Peninsula although modern methods have greatly increased camel densities in the entire region. In the United Arab Emirates (UAE), camel production is threatened by tick parasitism. However, no study has considered assessing the magnitude of the problem in the UAE. We conducted a study evaluating tick richness, abundance, and spatial distribution of ticks on camels in farms near Al Ain, UAE. In addition, we conducted a survey of farm owners to determine the control methods used to eliminate camel ticks.
Tick counts were made on 502 camels (). For each examined animal, visual counts of ticks were made on the entire body segregating the counts by head, neck, forelegs, hump, abdomen, back legs, and tail area. In addition, a total of 70 camel owners from the study area were randomly selected and surveyed about the tick control methods.
was the only species found during the study. The prevalence of ticks was 98% among the sampled animals. The mean intensity (tick load) was 25.8±2.4 ticks/host and the maximum number of ticks per animal was 102. Ticks were found in five vicinities that are on the border with Oman. The highest number of ticks on the body of the camel occurred on the tail area followed by the abdomen. Cypermethrin was the most commonly used acaricide (46.9%).
The high abundance of ticks reported in this study calls for the establishment of a good management strategy. In addition, finding ticks in vicinities in the UAE that are on the border with Oman suggests a cross-border movement between the two countries. Therefore, studying this movement is important to understand its role in the global circulation of some tick-borne diseases and the movement of acaricide resistance alleles among tick populations.
尽管现代养殖方法极大地提高了整个阿拉伯半岛的骆驼养殖密度，但骆驼养殖仍是该地区文化的一部分。在阿拉伯联合酋长国（阿联酋），骆驼生产受到蜱寄生的威胁。然而，尚无研究对阿联酋该问题的严重程度进行评估。我们开展了一项研究，评估阿联酋艾因附近农场中骆驼身上蜱的丰富度、丰度及空间分布。此外，我们对农场主进行了一项调查，以确定用于消灭骆驼蜱的控制方法。
对502头骆驼进行蜱计数（）。对于每头被检查的动物，对其全身进行蜱的目视计数，并按头部、颈部、前腿、驼峰、腹部、后腿和尾部区域进行计数分类。此外，从研究区域总共随机挑选了70位骆驼养殖户，并就蜱控制方法进行了调查。
是研究期间发现的唯一物种。抽样动物中蜱的感染率为98%。平均感染强度（蜱负荷）为每头宿主25.8±2.4只蜱，每头动物的蜱最多数量为102只。在与阿曼接壤的五个地区发现了蜱。骆驼身上蜱数量最多的部位是尾部，其次是腹部。氯氰菊酯是最常用的杀螨剂（46.9%）。
本研究报告的蜱的高丰度情况需要制定良好的管理策略。此外，在阿联酋与阿曼接壤地区发现蜱表明两国之间存在跨境流动。因此，研究这种流动对于了解其在某些蜱传疾病全球传播中的作用以及杀螨剂抗性等位基因在蜱种群中的流动情况非常重要。
