Many apiculturally important traits of the honeybee have medium to high heritabilities and are therefore capable of strong response to selection. However, the natural mating system of honeybees makes it difficult to exclude unselected males from matings and necessitates expensive procedures like artificial insemination or isolated mating stations. By manipulating ambient light and temperature, an Australian queen breeder has developed a novel system that delays the flight time of selected queens and drones. To assess the efficacy of this Horner system, drones and their assumed worker offspring were genotyped using microsatellite loci to test whether the workers were exclusively sired by the selected drones. The Horner system was found to provide at least 85% control of matings, equivalent to a 48% increase in the selection differential, when queens and drones are selected in a breeding program.
