The first long-term monitoring to document both activity and density of questing ixodid ticks in Vienna, Austria, is introduced. It was started in 2017 and is planned to run over decades. Such long-term monitorings are needed to quantify possible effects of climate change or to develop tick density forecast models. The monthly questing tick density at three sites has been observed by using a standardized sampling method by dragging an area of \(100\,\hbox {m}^2\) at each occasion. Popular recreational areas were chosen as study sites. These are the Prater public park, the wooded Kahlenberg, and a wildlife garden in Klosterneuburg. First results show a 3-year time series of nymphs and adults of the Ixodes ricinus species complex and Haemaphysalis concinna for the period 2017–2019. Whereas questing nymphs of the I. ricinus species complex were collected from February to November, H. concinna nymphs were only dragged from May to October. The peak of nymphal activity of the I. ricinus species complex was in May, that of H. concinna in August. In addition, a brief overview is given about ticks and tick-borne pathogens occurring in urban and suburban areas of Vienna.

维也纳（奥地利）探寻硬蜱的季节性密度的长期监测：设置和初步结果。

引入了第一个长期监测，以记录奥地利维也纳的 ixodid 蜱的活动和密度。它于 2017 年启动，计划运行数十年。需要这种长期监测来量化气候变化的可能影响或开发蜱密度预测模型。通过使用标准化的抽样方法，通过在每个场合拖动\(100\,\hbox {m}^2\)的区域来观察三个站点的每月任务蜱密度。热门的休闲区被选为研究地点。这些是普拉特公园、树木繁茂的卡伦贝格和克洛斯特新堡的野生动物花园。第一个结果显示了 3 年时间序列的硬蜱物种复合体和Haemaphysalis concinna的若虫和成虫2017-2019 年期间。虽然I. ricinus物种复合体的探寻若虫是从 2 月到 11 月收集的，但H. concinna若虫只在 5 月到 10 月被拖曳。I. ricinus种复合体若虫活动的高峰期为5 月，H. concinna的若虫活动高峰期为8 月。此外，还简要概述了发生在维也纳城市和郊区的蜱和蜱传播的病原体。
