Cuticular hydrocarbon profiles reveal age-related changes in honey bee drones (Apis mellifera carnica)

SUMMARY Cuticular hydrocarbon profiles of drone honey bees (Apis mellifera carnica) of different ages were compared by gas chromatography. Chromatograms of drones from three different colonies were similar and, despite some variations, showed the same patterns as a function of age. We suggest that in addition to behavioural changes, the surface hydrocarbon profiles of the drones might be used as a cue for the worker bees to discriminate between young and old individuals.
