The Drone Population of Natural Honeybee Swarms

Abstract
Summary The drones and queens in 59 swarms were counted, and the total number of bees estimated by weight. Ranges and mean values were: bees 1750to50 750 (mean 14 100), drones 0 to 1001 (mean 151, 1·06% of total). Swarms had 1, 2 or 3 queens. For 16 swarms whose time of emergence was known, swarms issuing between 9 h and 13.30 h contained as many or more drones than swarms issuing later in the afternoon.
