<p>The present invention concerns bees and beekeeping, aiming at reinforcing the bee's natural defences against parasitic diseases, in particular against attacks from varroa mites and other acarine mites living at its expense. It enables to compensate the deficiencies occurring during the bee's growth period. For that purpose, elements essential for the bee are restored, for example essential minerals to the surroundings of the hive, where the bees forage flowers for nectar, by enriching or restoring the surrounding grounds with fresh water diatoms.</p> |
