The honey vegetation of Russia is rich and diverse. It is estimated at millions of hectares of linden, fireweed, angelica, raspberry, buckwheat, sunflower, clover and many other valuable honeycomb. Bees provide not only high-calorie and healing honey, but also excellent medicinal substances: royal jelly, bee venom, propolis, pollen, fortified honey, which are widely used in medicine. Beeswax, which does not have an equivalent chemical substitute, is used in almost all industries. Bees are of great importance in modern conditions as pollinators of many eptomophilic crops. They are recognized as indispensable assistants to agronomists in their struggle to obtain high and sustainable yields.
