A wide prevalence of ticks, vectors of piroplasmosis and theileriosis of cattle Boophilus calcaratus (30-35 %%) and Hyalomma anatolicum (70-75%), and more arid semi-desert zones of mites detritum, carriers of piroplasmosis and
theileriosis of cattle, was found to be widespread in the foothill areas and floodplains of the rivers of the Kashkadarya and Surkhandarya regions. (10-15%) and Hyalomma anatolicum (85-90%).

The research- observational and experimental works were carried out in a private cattle belonging to population of Taylak, Urgut districts of Samarkand region. The regional fauna of ixodic ticks was defined. Such types of ticks belonging to the generation of Hyalommas, Rhipicephalus were registered as dominant type.
In all regions of the country, the infection rate of cattle with blood parasitic diseases (piroplasmidoses) averages 8-9%. Carriers of piroplastnidoses in cattle are pasture (ixodid) ticks. In particular, theileriosis is transmitted by ticks Hyalomma anatolicum and Hyalomma detritum, and piroplasmosis and babesiosis by Boophilus calcaratus.
