The influence of the time of year and the ambient temperature at the sex structure of the population of ticks genus Dermacentor. Activity ixodids has defined two peaks: spring and early autumn. Spring peak of activity continues with the third decade of April to early June, its characteristic feature is a high index of abundance of ticks (up to 113.5 individuals per flag-hour). Early autumn peak of activity begins in the second decade of August and lasted until the second decade of September, during this period the maximum index of abundance was 38.4 individuals per hour flag. In the spring, the peak of parasitism females prevailed over males and 3.5 times. Females are most active during the entire period of parasitism, but the most active in the temperature range 15-18ºS index abundance 77,4-83,1 individuals. The best temperature range for males ixodids from 12 to 18 ºC, and the index of abundance was 27,8-33,4 individuals on the flag-hour. It was established that low temperatures fall is most favorable for them than for females.
