[Repeated catching of taiga ticks on their permanent routes]

To determine seasonal dynamics of abundance of Ixodes persulcatus P. Sch. by standard methods the ticks collected on flag were marked with a nonrepeated group mark and returned into the registration route. As a result it was established that during the season of ticks' activity in the biotope of shrub meadows 26%, in the biotope of overgrown and trashed glades 14.4% and in the biotope of young aspen forest 13.8% of marked ticks were repeatedly found. Of all considered factors affecting repeated occurrence of ixodid ticks on a registration route, their transfer by wild animals, which use this route in their movements, may play an important part.
