During our examination performed in the period from 2010 to 2012, we collected ticks from 52 flocks of sheep and 38goat flocks. Ticks infestation occured in 15.97% (214/1340) of sheep and 16.93% (107/632) of goats. The result showed thepresence of Ixodes ricinus, Rhipicephalus sanguineus, R. bursa, Dermacentor marginatus, D. pictus, Haemaphysalis punctataand Ha. inermis. Additional to determination of tick species during the research, the sex ratio and the monthly influence ofmicroclimate conditions (temperature, relative humidity and precipitation quantity) on the dynamics of populations of tickswere followed. Obtained results indicate the importance of the impact of climatic factors on the population dynamics of somespecies of ticks as well as the dynamics and abundance of different sexes within established species of ticks.
