Abstract:

In the territory of Kirgiz SSR, I. crenulatus ticks are distributed in Tian-Shan, Osh,Issyk-Kul, and Talass Oblasts, and also in the Gorno-Badakhshanskoi Oblast of Tadzhik SSR. I. crenulatus ticks are found on marmots and in their burrows in all the places of habitat of marmots, from the foothill zone to the line of perpetual snows 1700 to 3700 meters above sea level. In their zonal distribution, I. crenulatus ticks are associated with various vegetation zones fir forest zone, meadow-steppe, semidesert, subalpine, and alpine meadows. The chief host of I. crenulatus ticks are the Altai Marmot and Long-tailed Marmot. However, they are sometimes found on other animals which have contact with marmots and with their burrows hares, foxes, polecats and others. The number of I. crenulatus on marmots varies in relation to the geobotanic and climatic conditions of the geographic position of the area. The greatest numbers of ticks are observed in areas with high humidity, comparatively high temperature, and dense vegetative cover. The number of ticks in marmot nests during the summer months is extremely low. The number of I. crenulatus ticks on marmots during the summer period changes. The maximum peak occurs in June and July at the expense of mass parasitism of larvae and nymphs. I. crenulatus ticks were not found in open biotopes, and this indicates their strict adaptation to the mode of life of their chief hosts, which are marmots. Author
