1 The primary cause of COPD is tobacco smoke (through tobacco use or second-hand smoke).  The disease now affects men and women almost equally, due in part to increased tobacco use among women in high-income countries.
Swarming is the process by which a new honey bee colony is formed when the queen bee leaves the colony with a large group of worker bees. In the prime swarm, about 60% of the worker bees leave the original hive location with the old queen. This swarm can contain thousands to tens of thousands of bees.
When they swarm, they create several swarm cells. The queen lays eggs in them, and then after about a week they cap those cells. After capping the cells, the queen departs with about 2/3 of the bees to try to make a new hive somewhere.
