Zimování včelstva
Babica, Ondřej
In the breeding of honeybees (Apis mellifera L.), the good health of the bee colony is an important prerequisite for successful overwintering. The condition of the colonies is affected by environmental influences, the influence of genetics or the health status of the bees. Well-developed pharyngeal glands allow bee feeders to provide developing larvae with quality royal jelly. The longevity of the winter generation of bees is influenced by a many of physiological factors, which distinguish them from summer short-lived bees. The main factors of longevity appear to be the level of proteins in the hemolymph, especially vitellogenin, the level of juvenile hormone or the pheromone ethyl oleate. The natural immune system or the effects of oxidative stress also play an important role in the overwintering of colonies. Recently, overwintering is threatened by viral infections transmitted by varroa mite.

According to the proposal, the intervention exercise program can be practiced by everyone and anywhere, even if the gyms are closed, for example for pandemic reasons. Eleven people took part in the exercise exercise program, and the control group also included eleven people. The EUROFIT test battery, consisting of nine tests, was chosen within the methodology. From the results, it should be emphasized that the experimental group improved on average by 0,1 try for endurance training standing on one leg, 1.89 seconds for tapping, also improved in the overhang in the forward bend by 3.23 centimeters, 13, 96 in the jump from the place, 3.17 repetitions in the sit-ups exercise, 4.79 seconds in the endurance in the squat, the only deterioration of the experimental group occurred in the shuttle run by 0.2 seconds, in the last dynamometry measurement test there was an improvement of 7.14 Newtons. In the control group, there was a slight deterioration in the first test by 0.1 attempts, we could also observe a deterioration in the tapping test by 1.33 seconds, a slight improvement of 0.98 centimeters occurred in the forward bend, the group only further deteriorated in all tests.
