An epizootological and epidemiological monitoring of red ticks was performed in the Krasnodar Krai in 2003-2006. This territory was conventionally divided into 5 agroclimatic zones. Among them are the worst – piedmont and the Black Sea Area. During the investigation 36 species of red tick were detected. They relate to three ecological groups (earth, earth-pasture and pasture-stall) and 3 types of parasitism –one-host, two-host and three-host. The strength of epizootic situation was promoted by general increasing the population of one-host red ticks – Boophilus annulatus (in 16 districts) and Hyalomma scupense (in 12), as well as newly appeared H. detrium – the main carrier of Teileria and Rhipicephalus bursa – the carrier of ovine pirolasmosis and R. turanicus. In 16 districts of the Krai antigens of tick-borne encephalitis virus in Ixodes ricinus, B. annulatus, Dermacentor marginatus, H. scupense, H. marginatum, H. punctata, R. rossicus; in 12 districts in I. ricinus, B. annulatus, D. marginatus, D. reticulates, H. punctata 0 RNA virus of Congo-Crimean hemorrhagic fever and in I. ricunus, B. annulatus and D. marginatus – tularemia. The West Nile fever virus was isolated during studying bovine blood sera. The regular acaricide treatments of cattle allowed reducing the incidence of hemosporidial infections by 80%, minimizing forced slaughter and mortality of animals. Monitoring investigations of ixodofauna and acaricide treatments of cattle are recommended to control the number and to prevent spreading transmissible diseases.
