Mathematical modeling of ixodic ticks of the Non-Black Earth Zone

The article discusses the impact of exogenous factors on the population of ixodic ticks. It is known that parasitic arthropods including ixodic ticks, are very susceptible to changes in climatic factors of a certain habitat. For the development of a population, it is necessary to study many factors: a certain air temperature, humidity or rainfall, daylight hours, cloud cover, and atmospheric pressure. The choice and number of hosts, the time limits of bloodsucking and diapause, and activity peaks depend on exogenous factors. In the Kaluga Region, cases of hemosporidial infections, anaplasmosis among animals, and borreliosis among people are recorded annually. Two species of ixodic ticks live in the Region: Ixodes ricinus and Dermacentor reticulatus. Mathematical modeling in parasitology opens up great opportunities for predicting outbreaks of vector-borne infections and infestations without serious material costs. As a result, data were obtained on the strongest effect on the arthropod population of mean atmospheric pressure. With a simultaneous increase in the monthly average values of temperature, humidity and atmospheric pressure, the number of active ixodic ticks will decrease. The advantage of the applied modeling allows taking into account the impact on the observed object of a combination of all factors and their interaction effects.
