Monitoring of two tick species (Ixodes persulcatus Schulze 1930 and Ixodes pavlovskyi Pomerantsev) was performed in four city parks of Tomsk, Russia (Camp Garden, University Park, Southern Cemetery, and Polytechnic Stadium) and in a control wild biotope in city environs (Kolarovo) in 2002-2013. Ticks were collected by flagging repeatedly after each 10 ± 1 days, starting from the disappearance of the snow cover till the end of tick activity (April-August). Gradual penetration of both tick species into city parks was demonstrated. In the wild biotope, I. persulcatus dominated during the whole period of monitoring, forming about 95% of tick population, whereas in urban biotopes I. pavlovskyi became the dominant species. Two peaks of population density during each season of spring-summer activity were observed in both species. Possible explanations of the phenomena are discussed.
2002年至2013年期间，在俄罗斯托木斯克的四个城市公园（营地花园、大学公园、南部公墓和理工体育场）以及城市周边的一个对照野生生物群落（科拉罗沃）对两种蜱虫（全沟硬蜱舒尔茨1930年和帕氏硬蜱波梅兰采夫）进行了监测。从雪被消失到蜱虫活动结束（4月至8月），每隔10±1天重复进行一次拖旗法收集蜱虫。结果表明，两种蜱虫都逐渐渗透到城市公园中。在野生生物群落中，全沟硬蜱在整个监测期间占主导地位，约占蜱虫种群的95%，而在城市生物群落中，帕氏硬蜱成为优势种。在春夏季活动的每个季节，两种蜱虫的种群密度都出现了两个峰值。文中讨论了这些现象的可能解释。
