Development and productivity of honeybee colonies administered food supplements in spring

摘要

The aim of the study was to assess the effect of the diet supplements Bee Tonic, Beeodine and Immunbee solution on the quality of honeybee colonies in the spring. The administration of dough containing l3eeodine to bees may have had a positive effect on their vitality, thanks to which they occupied the largest space in the nest (4.1 inter-comb spacer, on average) on April 15, and in late April the occupied space in this group increased almost 2.5 times. The observed colonies had a similar number of cells with brood at the 1st and 2nd measurements. They also showed a similar growth of brood. The colonies given cake with Beeodine were characterized by the highest unit productivity (4.6 kg). Similarly, the production of brood, bees and wax was stimulated by the addition of Immunbee solution (4.3 kg), whereas BeeTonic did not produce such an effect.
