Drone rearing
When a queen breeder practises drone rearing in order to naturally mate his queens, he saturates the area with drones. However, only a proportion of his drones will visit the drone congregation areas, which consist of a representative sample of the colonies surrounding his apiary. The influence exerted by the breeder is not negligible, but mating at a mating apiary will always result in hybrid offspring. These are F1 queens.
Caste determination depends on three factors: the type of egg (fertilised or unfertilised), the food provided to the larvae, and the type of cell in which the egg was laid. The drone develops from an unfertilised egg laid in a drone cell. After being laid, a male requires twenty-four days to develop, passing through four developmental stages.
Drone rearing in honey bees – biology, genetics and practical applications
This document provides a comprehensive overview of drone (faux-bourdon) biology, morphology, genetic role and rearing techniques in honey bees (Apis mellifera). Drones develop from unfertilized eggs (haploid) laid in drone cells and require about 24 days to reach adulthood. Their primary role is to transmit the queen’s genetic material during mating.
The biological cycle is described in detail, from egg and larval stages to the pupal stage and adult emergence. Drones depend entirely on worker care during early life. Sexual maturity is reached about 12–15 days after emergence. Mature drones fly to drone congregation areas (DCAs), where mating with queens occurs. After successful copulation, drones die shortly afterwards.
Morphologically, drones are larger and heavier than workers, with highly developed eyes and antennae that enhance flight and mate detection. They lack a sting, wax glands and pollen-collecting structures. Their internal anatomy is largely devoted to reproduction.
A major focus of the document is the genetic importance of drones. Because they are haploid, drones pass on their genes without recombination, making them key tools in selective breeding. Basic genetic concepts such as haploidy and diploidy, dominant and recessive genes, and homo- and heterozygosity are clearly explained in relation to bee breeding goals.
The author describes several practical methods for drone rearing, depending on the objective: natural mating in mating apiaries, isolated mating stations, or instrumental insemination. Successful drone production requires strong, well-fed colonies with low Varroa infestation. Techniques are also presented to obtain drones very early in the season or to maintain them late in the year.
Finally, the impact of Varroa destructor on drones is analysed. Early parasitism significantly reduces sperm production (up to 53%) and severely impairs flight performance, highlighting drones as a sensitive indicator of colony health.
Conclusion: targeted drone rearing is a cornerstone of modern bee breeding. It demands careful management and effective Varroa control but plays a decisive role in mating success and the genetic quality of future queens.
