At present, the ixodofauna of the Tyumen region is represented by six species of ixodid ticks – these are Ixodes persulcatus Schulze, 1930; Dermacentor reticulatus Fabricius, 1794 (D. pictus, Hermann, 1804); D. marginatus Sulz, 1776; I. apronophorus P. Sch., 1924; I. (Exopalpiger) trianguliceps Bir., 1895 and I. (Ceratixodes) plumbeus, Kirsch., 1936. Three species of ixodid ticks parasitize cattle: I. persulcatus, D. reticulatus, D. marginatus. The remaining three species of ticks, Ixodes apronophorus, Ixodes strianguliceps, and Ixodes plumbeus, belong to the nest-like parasitic type and therefore are less dangerous parasites for large mammals. The most widespread ticks of the genus Ixodes and Dermacentor in the context of all natural-geographical zones of the region are ticks of the genus Dermacentor, their dominance index was 54.8%. As a result of observation, it was noted that the temperature and humidity of the air affect the activity of ixodid ticks of the genus Dermacentor in nature. Thus, the peak of ixodid activity in the spring period fell on days when the air temperature reached values from 16 oC to 26 oC, and in autumn from 15 oC to 21 oC, while lower and higher humidity indices had a depressing effect on ixodid mites of the genus Dermacentor.
