The queen bee breeding is a wide field. In addition to the usual breeding systems, various accessories are required. Whether paint, opalite or the Umlarv needle. Traditionally, many things of the accessories are also articles that the beekeeper builds himself. These DIY items are increasingly being replaced by industrial products. The best example of this is the Weisel beaker, which was made from wax in the vegan state and is now offered by Nicot from plastic in the Nicot breeding system.
