Okay, having taken a chill pill or 10, I'll start again.
My understanding is that swarming is a natural reproductive behaviour under certain conditions.
After reviewing everything, a few points did occur to me.
Traditionally, people keep bees usually for either profit or put food on the table and under these conditions, swarming is completely detrimental simply because it reduces production.
The factor for the spread of disease is a valid point, but not something I have come across/read about and so, know nothing about.
In hind sight, I should have left out the 'controlling' aspect out of the original post, I now see that this has come across as a derogatory reprimand and set your teeth on edge and did not come across as was intended. Being in control of things is just what we do, for good or bad but, feel it is sometimes to the detriment of other species.
Because I became aware of the fact that we do tend to do things in the way we do, simply because that is the way its always been done. I tend to try to step off to the side and look at things with fresh eyes. Hence my comment on constantly checking things out, questioning everything. Its not a point of finding what is wrong about something, but finding missing links that may in fact be key factors.
I dont keep bees just for their honey and dont mind if they dont have enough for me. My hive is there for many reasons.
1 I always wanted to keep bees and then found a method that would make that possible.
2. Its also my schoolroom where I can learn from them.
3. Its another layer to my permaculture back yard= I work to create a balanced mini-eco system rather than, for example, have fence to fence grass that other do seem to enjoy. I enjoy studying what I call the intricate orchestrated randomness of nature.
