The present study was aimed at determining the effect of carbon dioxide on maturation and breeding value of drones reared for artificial insemination of honey bee queens. The study was made in 2000-2003 on drones from two rearing series - the first reared in II-III decade of June, while the second in II-III decade of July. In each series, drones were reared in two colonies. Drones reared in one of the colonies underwent ten minutes long CO2 anaesthesia in the first day of their life. Drone breeding value was evaluated at the age of 8, 10, 12 and 14 day of their life, taking into account such parameters as: percentage of drones delivering semen, volume of ejaculate collected from one drone, number of drones required for collecting a dose of 8 mcl of semen, number of spermatozoa in 1 mcl of semen. It was found that CO2 anaesthesia of drones directly after their emerging affects favourably their breeding value, accelerating maturation of breeders. The percentage of drones delivering semen at the age of 8-10 days was higher in CO2 anaesthetised group by 8.11 and 9.24 percent, respectively. In order to obtain an 8 mcl dose, a smaller number - by half - of 8-10 days old drones anaesthetized with CO2 was required for semen collection
