Abstract:
In order to replenish stocks of food for the winter and to stimulate the growth the colonies are fed with the sugar syrup. The aim of our study was to investigate the influence of the preparation of effective microorganisms on winter resistance and productivity of bee colonies, to determine the optimal dose and method of autumn and spring feeding of bees. Use of the feeding of effective microorganisms 1.5 ml / l of syrup during autumn feeding improves resistance of bee colonies by 1.07%. To stimulate the females’ fertility, brood rearing and rising of the productivity is recommended to feed honey bees every 12 days using 1 liter of syrup with 1.5 ml of the feed effective microorganisms before the main harvest of acacia.
