[The longevity of the tick Ixodes ricinus (Acari: Ixodidae) in Central Russia].
The longevity of the tick Ixodes ricinus has been studied on 27 samples from a wild population of the Moscow Region. Ticks were kept in small cages and glass tubes under conditions close to natural. About 2/3 of the specimens collected in spring survived till the next spring and later died out gradually during the second season of their activity. Very few specimens reached the beginning of the third winter in their life, but apparently none of them survived the end of the winter. The life span of males was the same as that of females. No mass activation of adult ticks was recorded in the autumn of the year of their molting. It seems that the rise of the autumnal density of adult ticks depends mainly on the increased activity of the females which molted from nymphs last year.
