Glossary
The controlled process of producing new queen bees through larval grafting, cell building, and mating management. Queen rearing is a specialized skill that allows beekeepers to propagate genetics from their best-performing colonies rather than purchasing queens from external sources.
Purchasing queens is convenient but limits your operation to someone else's genetics, which were selected for their environment and priorities, not necessarily yours. Raising queens from your own best colonies (the survivors, the gentlest, the most productive, the most hygienic) produces queens adapted to your specific conditions: your local climate, your flora, your pest pressures, and your management style. Local genetics, over time, outperform imported genetics for colony survival.
The most common queen rearing technique, developed by G. M. Doolittle in the 1880s, involves these steps: Select a donor colony (your best breeder) with the traits you want to propagate. Graft: use a grafting tool to transfer 12- to 24-hour-old larvae from the donor colony into artificial queen cups. The cups are placed in a queenless "cell builder" colony with abundant nurse bees and food. The nurse bees feed the grafted larvae royal jelly, triggering queen development. After 10 days, the sealed queen cells are placed in individual mating nucs. Virgin queens emerge, fly to drone congregation areas, mate with 12 to 20 drones, and begin laying within 1 to 3 weeks.
Successful queen rearing requires drones to be present for mating, meaning the process must coincide with drone production season (late spring through early fall in most climates, nearly year-round in Florida). Planning backward from the introduction date: queens take 16 days from egg to emergence, plus 1 to 3 weeks for mating and laying onset. A grafting operation started today will produce laying queens in approximately 4 to 6 weeks.
Grafting requires practice but is learnable by any beekeeper with steady hands and patience. The first attempts often have low acceptance rates (25-50%). With practice, experienced grafters achieve 80-90% acceptance. The investment in equipment is modest (grafting tools, queen cups, cell bar frames, mating nucs). Many beekeeping associations offer queen rearing workshops.
A single cell builder colony can produce 15 to 30 queen cells per grafting round, with rounds possible every 10 to 12 days during the season. A dedicated queen rearing operation can produce hundreds of queens per season from a few cell builder colonies and a bank of mating nucs.
