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 the summer season approaches, and you are ready to harvest honey, it is a good idea to check below the hive's cover every two or three weeks. This will allow you to check the progress being made, and allows you to see how many frames are full of capped honey.
