Drone rearing
Within the colony, the role of the drone is often poorly understood or even regarded as secondary. Yet males play a fundamental role in the transmission of genetic diversity. Gathered in so-called drone congregation areas comprising 1,000–15,000 individuals, they originate from many different colonies, sometimes located 10–15 km away. During the so-called drone flight, they mate with queens in succession (often up to 20 consecutive matings), thereby ensuring genetic mixing and preventing inbreeding.
Drone (male) rearing – key principles for successful queen mating
Producing sufficient numbers of high-quality drones is essential for any queen-rearing program. Drones transmit genetic traits, making their rearing a critical factor in controlled mating and selection. The main objective is to genetically saturate the mating area to ensure high-quality fertilization.
Precise timing is crucial. A queen reaches sexual maturity about six days after emergence, whereas drones become sexually mature only after 15–16 days. These periods must be carefully synchronized in the breeding schedule. Drones generally lose their fertility about one month after emergence, so drone production must begin early in the season.
Drones should be reared in very strong colonies (at least 6–7 brood frames) that can provide sufficient nursing care. Such colonies must not be weakened by splitting and must be closely monitored for swarming. Alternatively, drones can be produced in dedicated drone colonies or queenless units, provided that selected drone brood is regularly introduced. Drones produced by laying workers are unsuitable due to poor fertility.
Drone frames should be introduced regularly (approximately every 10 days). Drone cells are larger than worker cells (around 640 cells per dm²) and can be produced using special foundation or by allowing free construction from a starter strip. Clear identification of drone frames is recommended.
Enhanced feeding is required: protein supplements (pollen or substitutes) and stimulating sugar syrup (50/50) support proper development and prevent workers from expelling drones. A pollen-rich environment further improves drone quality.
As a guideline, about five drone colonies are needed for 100 mating nuclei to ensure adequate genetic coverage. Drone colonies should be placed in or near mating areas. Optimal mating flights occur at temperatures of 18–20 °C, with sunshine and low wind. Drones gather in fixed congregation areas that may host thousands of individuals from many colonies.
In summary, successful drone rearing depends on early planning, strong colonies, adequate nutrition and precise synchronization with queen rearing.
