The article deals with the regulation of the number of ixodid ticks in the Non-Chernozem zone using mathematical modeling of ixodid ticks that live in the Kaluga region of the Russian Federation. Statistical data is taken for the period of the decade of the research. In the Kaluga Region, two species of ixodid ticks are presented, which are Ixodes ricinus (European forest) and Dermacentor reticulatus (pasture), both demonstrating two regular peaks of their activity in spring and autumn. Analytical and calculated mathematical models of the population of ixodid ticks are obtained based on the composition of three or four factors, including: average monthly air temperature per year, average monthly relative humidity per year, average atmospheric pressure per year. The analysis of the results shows that it makes sense to take into account the composition of the first three factors, excluding cloud cover, as long as the cloud value is minimal is minimal in the Kaluga Region and thus cannot affect the results of the mathematical calculations. There are theories which are based on the hypothesis that both the temperature and humidity have an effect on the size of the ixodid ticks’ population. The obtained models presented in the article prove strong influence of these parameters, but moreover accents the monthly average atmospheric pressure having the greatest influence on the parasites’ population.
