Abstrakt

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 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 theIxodes ricinusspecies complex andHaemaphysalis concinnafor the period 2017-2019. Whereas questing nymphs of theI. ricinusspecies complex were collected from February to November,H. concinnanymphs were only dragged from May to October. The peak of nymphal activity of theI. ricinusspecies complex was in May, that ofH. concinnain August. In addition, a brief overview is given about ticks and tick-borne pathogens occurring in urban and suburban areas of Vienna.
