Physiology of cold tolerance in the bark beetle, Pityogenes chalcographus and its overwintering in spruce stands

Popis výsledku v původním jazyce

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. Prior to overwintering, the beetles accumulated carbohydrate reserves in the form of glycogen and trehalose. These reserves were partially converted to glycerol during peaking winter so that glycerol concentration reached 1.4 M in average, which corresponds to approximately one quarter of the beetle dry mass. Whole body supercooling points decreased from -12.8 degrees C in average at the beginning of dormancy (August) to -26.3 degrees C in average during peaking winter (January). More than 75% of January-collected beetles survived at -5 degrees C for 30 days, at -15 degrees C for 60 days and more than 40% of them survived at -26 degrees C for 12 h. High resistance against inoculation of body fluids with external ice crystals, and low mortality, was observed when January-collected beetles
