Abstract : Characteristic changes in water content and integument permeability of ticks occur during their feeding. Both the permeability and water content are maximal at the stage of slow feeding while both of them decrease simultaneously at the stage of rapid feeding. It is suggested that at the final stage the excessive water is eliminated by means of the salivary glands activity. The 'evaporative' way of food concentration and water balance regulation is of value at the first stage only. In engorged females the maintenance of water balance is based on the decreased integument permeability and this peculiarity develops during the feeding period. (Author)
