During the tick season, females were placed in plastic test tubes under the forest litter. Larvae and nymphs of different ages 5-320 days reared from them were fed in the laboratory from April to October and immediately returned to the taiga. During the observation period April till October the average 10-day temperature of the forest litter was over 5C for 170-180 days, 10C for 130-140 days, 15C for 90-100 days, and 18C to 22C for 70-80 days end of June to September.
