Re: Definition of "Artificial Swarm" ??
First, define a primary swarm. A primary swarm is a group of bees that separates from the parent colony with a queen (usually the old queen but sometimes a virgin) and moves to a new home. The bees in a swarm generally make up about 2/3 of the adult bee population of the parent colony with young adult bees in a rough proportion of 3/5 while foraging age bees are about 2/5 of the total swarm. As MP states, drones often accompany a swarm. I have seen fuzzy recently hatched bees along with older bees with severely damaged wings in swarms.
With this definition, a split where the queen and most of the foraging age bees are separated from the young bees does not constitute an artificial swarm. Such a split would present an extreme unbalanced condition with too many old and too few young bees.
One of my preferred methods is to take 3 frames of mostly sealed brood from one colony, place them in an empty hive, then swap with the position of another colony that is preparing to swarm. Removing 3 frames of brood along with all queen cells will almost always stop the swarming urge in the first colony. Removing all the foraging bees will almost always stop the swarming urge in the second colony. The 3 frame split has young bees in abundance and the full field force of the second colony so it usually makes a crop of honey along with the parent hives. Keep in mind that 3 frames of brood in Dadant size frames is nearly the equivalent of 5 Langstroth deep frames. I do not consider this to be an artificial swarm. It is a practical and effective method to prevent swarming while maintaining honey production. When the new queen emerges, this colony will work nearly as hard as a swarm to "catch up" with the parent colonies.
