The influence of drone presence in bee families on the drone brood rearing

Abstract

The incubation of drone brood by bees was studied. It was elicited that excision of drones from the family during intensive
development in June, July, increases the number of drone brood.
The growth of bee brood rates from 4.0 % till 7.6–11.7 %, besides the drones development is 30 days longer. The Ukrainian
Steppe breed bee-families actively correct the number of drones
in swarm. So, after drones were completely withdrawn from the
family, they were found again three-four days later much more
in number than was the brood itself. It is possible that drone
absence welcomed strangers to the bee-family.
