AGE AND SEASONAL TOLERANCE VARIABILITY OF HONEY BEES TO HYPERTHERMIA
Age and seasonal tolerance changeability of working bees to hyperthermia was studied. The bees under study belonged to bee families contained in hives kept constantly either in shadow or under open sunbeams. It is established that the highest hyperthermia resistance has been observed in bees of younger age groups as well as of spring and autumn generations. The sunrays warming of a beehive results in temperature increase of the bee brood and in hyperthermia tolerance decrease in growing bees.
