The two ixodid tick species Dermacentor reticulatus (Fabricius) and Dermacentor silvarum Olenev occur at the northern distribution limit of the genus Dermacentor in Eurasia, within the belt of \(34{-}60^\circ ~ \hbox {N}\) latitude. Whilst the distribution area of D. reticulatus extends from the Atlantic coast of Portugal to Western Siberia, that of D. silvarum extends from Western Siberia to the Pacific coast. In Western Siberia, the distribution areas of the two Dermacentor species overlap. Although the two tick species are important vectors of disease, detailed information concerning the entire distribution area, climate adaptation, and proven vector competence is still missing. A dataset was compiled, resulting in 2188 georeferenced D. reticulatus and 522 D. silvarum locations. Up-to-date maps depicting the geographical distribution and climate adaptation of the two Dermacentor species are presented. To investigate the climate adaptation of the two tick species, the georeferenced locations were superimposed on a high-resolution map of the Köppen–Geiger climate classification. The frequency distribution of D. reticulatus under different climates shows two major peaks related to the following climates: warm temperate with precipitation all year round (57%) and boreal with precipitation all year round (40%). The frequency distribution of D. silvarum shows also two major peaks related to boreal climates with precipitation all year round (30%) and boreal winter dry climates (60%). Dermacentor silvarum seems to be rather flexible concerning summer temperatures, which can range from cool to hot. In climates with cool summers D. reticulatus does not occur, it prefers warm and to a lesser extent hot summers. Lists are given in this paper for cases of proven vector competence for various agents of both Dermacentor species. For the first time, the entire distribution areas of D. reticulatus and D. silvarum were mapped using georeferenced data. Their climate adaptations were quantified by Köppen profiles.

在欧亚大陆Dermacentor属北部分布范围的疾病传播媒介：D。reticulatus和D. silvarum。

两种ix科tick种Dermacentor reticulatus（Fabricius）和Dermacentor silvarum Olenev发生在欧亚大陆Dermacentor属的北部分布范围内，位于纬度\（34 {-} 60 ^ \ circ〜\ hbox {N} \）。网纹石。的分布区域从葡萄牙的大西洋海岸延伸到西西伯利亚，而石，木的分布区从西伯利亚西部延伸到太平洋海岸。在西西伯利亚，两个Dermacentor的分布地区物种重叠。尽管这两种tick是疾病的重要媒介，但仍缺少有关整个分布区域，气候适应性和证明的媒介能力的详细信息。编译了一个数据集，得到了2188个地理参考的网纹石D和522个石.。绘制了描绘两个Dermacentor物种的地理分布和气候适应性的最新地图。为了研究两种壁虱物种的气候适应性，将地理参考位置叠加在柯本–盖格气候分类的高分辨率地图上。网纹石。的频率分布在不同的气候下，出现了与以下气候有关的两个主要峰值：全年温暖的温带降水（57％）和全年寒冷的北温带（40％）。D. silvarum的频率分布还显示了两个与寒带气候有关的主要峰，常年降水（30％）和寒冬干燥气候（60％）。在夏季温度方面，Dermacentor silvarum似乎比较灵活，温度范围从凉到热。在夏季凉爽的气候下，不会发生网纹杜鹃（D. reticulatus），它更喜欢温暖的夏季，在较小程度上更喜欢炎热的夏季。本文列出了两种Dermacentor的各种药物已证明具有载体能力的案例种类。首次使用地理参考数据绘制了网状石楠和石楠木的整个分布区域。他们的气候适应性通过柯本气候曲线进行了量化。
