Queen rearing is one of the most important areas of beekeeping. After explaining the breeding objectives, the three most common methods for rearing queen bees are described: Breeding in the queenless colony; breeding via the pre-brood box; breeding via starter and finisher. Special attention is also paid to the selection and presentation of the breeding material, selection and preparation of the care colony, controlled mating and the safe introduction of queens into the colonies.
