Drones

1_141x141.jpgPurpose of drones is insemination of young queen bees. Drones do not perform any other functions in the colony. They develop, as already noted, from unfertilized eggs, which the queen lays in the honeycomb cell of a slightly larger size than normal bee cells. Larvae hatch from eggs at the end of the third day. Nurse bees feed larvae with jelly during the first three days (this jelly differs from the composition of jelly given to larvae of worker bees and queens), and then they feed them with a mixture of honey and bee bread. Larval stage in an open drone cell lasts 6 days, and stage of larvae and pupae in a sealed box -14 days. Thus the development of drone goes on within 24 days.

A drone is significantly larger than a worker bee. It weighs about 0.2 g. To feed drone larvae bees use three times more food than to feed larvae of worker bee. Therefore when bringing up and feeding drones the colony increases the wastage of feed significantly. Organs of the drone’s body are not suitable for work. Drones have short proboscis, they have no baskets to transfer pollen, no wax and other glands. Drones don’t have stings, but they have strong wings and very large compound eyes.

Drones reach sexual maturity on the 12-14th day of their life, and sometimes even later (on the 20th day). They mate with the queen in the air during the flight in the warmest time of a day. After mating with the queen the drone dies as the part of its genital organ is torn off and remains as a tail in the reproductive system of the queen.

Drones appear in the bee colony in the late spring or early summer. Their number in the hive can reach several hundreds or even thousands. Drones are taking part in the transmission of hereditary qualities to brood, so beekeepers seek to develop drone brood only in highly productive colonies. To avoid the appearance of drone brood in other colonies, the bees are given frames for building, with wax sheets of artificial honeycombs, and replace the queen bees in appropriate time (in colonies with old queen bees there are usually more drones than in colonies with young queen bees).

Though the drones are attached to their colonies (in which they hatched out), they often fly to other colonies. During the flow time bees accept them freely. When honey flow stops honey bees expel drones from the hive and they die from hunger and cold. The drones are allowed to stay for winter only in colonies without queens or with queens that haven’t mated. Sometimes they are left for the winter in colonies with young queens that have mated too late and haven’t laid eggs yet in this season. Overwintered drones are useless for mating.
