Временная структура численности таежного клеща в пригородной зоне Иркутска

The abundance of questing imago Ixodes persulcatus stayed stably low during 1970-1985 in Irkutsk suburbs and varied within 0,2-3,1 ticks per flag/hour. The trend towards steady increase of the imago abundance have been formed during 1986-2006. As a result the average ticks' abundance had grown more than 80 times, it was caused by a number of factors including climate changes that occurred during this time. Analytical equalization, establishing communication of ticks' abundance with climatic parameters during all period of supervision is presented.
