Abstract

In the modern world, the problem of honey-bee colonies’ death is acute. An intensive search is underway for environmentally friendly preparations that could stimulate the bees’ resistance to various diseases, as well as have a beneficial effect on the body, thereby contributing to an increase in honey productivity. Preparations based on live probiotics bacteria of Lactobacillus and Bacillus subtilis genus are currently becoming increasingly popular. The use of probiotics in beekeeping allows to destroy pathogenic microflora, strengthen immunity and activate the body’s metabolic processes. The aim of the study was to determine the influence efficiency of probiotic preparations complex ApiVrach, SpasiPchel, Pche-loNormoSil during the period of spring development on the economically useful traits of honey-bee colonies. Studies have found that when probiotics are added to sugar syrup in the spring, the brood growth of bee colonies and their honey productivity are activated. The flight activity of bees when feeding with probiotic preparations increased by 43.6% from the control group. When assessing the dynamics of the bee colony’s strength, it was found that the usage of “ApiVrach” + “PcheloNormoSil” combination allows increasing the amount of sealed brood by 4 times, and the strength of the bee colony - by 1.5 times. Also, this combination of preparations made it possible to obtain the largest amount of total honey yield by 19.2% more than the control group, by 3.0% more than the group that received the ApiVrach + SpasiPchel complex and by 1.1% more than when using ApiVrach.
