Physiology of cold tolerance in the bark beetle, Pityogenes chalcographus ant its overwintering in spruce stands
Original language description
The seasonal development of physiological features underlying gradual acquisition of relatively high cold tolerance in overwintering adults of the bark beetles, /Pityogenes chalcographus/ was described. Glycogen and trehalose reserves are converted to glycerol during winter. High concentrations of glycerol help increasing the supercooling capacity. Beetles avoid freezing and, theoretically, can survive any conceivable winter cold. Field data, however, show that winter survival ranges from 24% to 69%. Meaning of laboratory-assays for field-survival estimation is discussed.
