Here is an example of a little bit of science mixed with a lot of imagination. To attribute swarming behavior to the lessening of "queen substance" without having a way of measuring such a substance, is pure speculation. Besides, a five frame nuc will swarm once it is packed with bees. Swarming has more to do with congestion than anything else. By getting the bees up in the supers, or otherwise taking excess bees out of the brood nest, congestion is reduced and the urge to swarm is suppressed. C.C. Miller noted that hives with first year queens are less apt to swarm, even when crowded, so he advocated requeening in spring to prevent his comb honey hives from swarming. My own theory, since we are into speculation mode, is that all hives want to swarm but they wait for the right conditions. Swarming is an expression of the urge to multiply colonies. The right conditions would be plenty of pollen and nectar coming in, and an "apparent" surplus of bees, given the size of the nest. pb -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
