Queen bee breeding is a meticulous process that requires precise timing and careful planning. The success of raising high-quality queens depends on the synchronization of drone maturity, the establishment of nurse colonies, and ensuring the right genetic lineage.
The Timing of Queen Rearing
Queen breeding can only begin when capped drone brood is present in the colony. On this day, a queen cell can be introduced into a nurse colony. The development cycle of drones is crucial for timing the introduction of queen cells.
Drone Development Cycle
- After their first orientation flight, drones begin to emerge en masse after 21 days. At this point, drone combs should be added to the hive.
- Drones hatch 24 days after being laid and take another 14 days to mature, completing their 38-day development cycle.
- In contrast, queens hatch after 16 days and mature in 10 days, making their total development cycle 27 days.
- A queen cell should be introduced into the nurse colony when drone brood reaches 11 days of age, which coincides with the capping of drone brood.
Selecting the Breeding Queen
The traits of the colony are transmitted through the queen's lineage via royal jelly. Simply taking eggs from a high-quality queen is not enough; the eggs must also be reared by bees from the same genetic background. To ensure superior queen quality, both the starter colony and the nurse colony should originate from the same mother line. To enhance egg-laying potential, the breeder queen should be confined for a week to regulate egg-laying.
The Role of the Starter Colony
A starter colony is a hive with a high population of young bees and all capped brood. Since the colony has no choice, it will eagerly accept and nurture young larvae placed in queen cells. In the nurse colony, open brood frames are placed next to the introduced queen cells to attract young nurse bees to feed the larvae. Moving larvae from the starter colony to the nurse colony should only be done in the first half of summer when the swarming season is still active.
Establishing a Finisher Colony
Finisher colonies should be created before the nectar flow begins, as robbing behavior increases later in the season. Wait 5 days after establishing the queenless nurse colony, during which any unwanted queen cells are destroyed. After 5 days, the nurse bees will have a sufficient supply of royal jelly to properly feed the introduced queen cells, leading to higher-quality queens. Inside the finisher colony there must be bee bread and honey, and open brood frames should be placed near the queen cells to attract nurse bees.
Choosing the Right Finisher Colony
- Colonies with 2-3-year-old queens are preferred, as older queens are more likely to swarm than younger ones.
- A strong colony covering an entire hive body should be selected, reinforced a week before with additional brood frames if necessary.
- Capped brood frames are placed at the hive's edges, followed by pollen and honey frames, then open brood frames, and finally the queen cells.
The Importance of a Drone-Producing Colony
A drone-producing colony (or father colony) serves as a genetic pool for drone stock, passing down the best colony traits. Drone combs should be added only after the first worker bee generation emerges, as drone larvae require a substantial amount of royal jelly. The ideal father colony is a strong, proven hive that has survived 2-3 summers. Only about 10% of all drones in a colony will actually mate with queens, so maintaining a stable drone population is essential for breeding success.
Conclusion
Raising high-quality queen bees requires precise planning and careful coordination of drone and queen development. By synchronizing the maturity of drones, properly preparing nurse colonies, and ensuring strong genetic lines, beekeepers can consistently produce superior queens.
