Do Glycogen Content and Thermal Preference in Worker Bees Vary Depending on Geographical Origin? A Comparison of Carniolan Honeybees, Central European Honeybees and Caucasian Honeybees

Among the honeybee subspecies, Polish beekeepers most commonly rear three of them, i.e., Apis mellifera carnica, A. m. and caucasica. They differ in morphological physiological features. Our goal was to find a linkage between their thermal behaviour body glycogen content that could be decisive for wintering perspective. We compared temperature preference concentration six groups subspecies obtained from hives two seasons, on 12 May 2021 (summer bees) 20 September 2020 (autumn bees preparing wintering). In Carniolan Central European honeybees, worker bodies higher autumn than summer bees. The Caucasian deviated this pattern. choice ambient by given depended neither season nor geographical race.
