Abstract

This work was done in the laboratory and in the field and includes questions of development, behavior, and viability of ticks, their propagation and season of attack.

H. marginatum: Two-host tick, larvae and nymphs parasitize mainly birds, also hares, adults on, all kinds of domestic animals.

This tick inhabits the southern areas of the Soviet Union. Northern boundary of mass propagation is 46 to 49.5° northern latitude and yearly isotherms +90. Host heavily infested are lowlands and foothills of steppe, forest steppe; and low mountain forest zone. In high mountain belts and deserts, this tick is rare. Birds must play a part in the distribution of this species during seasonal migration. By this phenomenon, in particular, one can explain isolated. findings of H. marginatum in northern latitudes.
