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.
You certainly don't want your colony to swarm. But you do want. to encourage lots of bees for the big nectar flow. So you do all. the things you can to grow your colony and to prevent the bees. from splitting and leaving (thereby creating a swarm). But. despite your best intentions, your hive might swarm. It happens. to the best beekeepers.
