Hi all
Just got back to the list so this post is to stuff from a while back:
Donald Aiken wrote in response to my post about having tried to kill
a swarm that had been aggravated with H2S and it having gone very
quite instead of dying.

I asked around a bit about H2S and aparently, the point at which it
becomes toxic to a person is when you can no longer smell it.
Apparently it binds to certain active sites in enzymes with metal
ions in or something to that effect.
When one uses smoke, there must be a certain amount of CO carbon
monoxide that would have a similat effect, but to a lessor degree to
that of H2S.
What I would be interested to know is if anybody has noticed this
peacefulness of the bees near other sources of either of these
gases as well or any other gases such as hydrogen cyanide (gold mines
in Canada and Australia?) and maybe near highways and so on. It often
has intrigued me that a hive in the middle of my town is extremely
passive even al;though it is directly above a busy road in an oak
tree? Could this be a factor? The bees response to anger is blind
because all their receptor sites for anger pheremones are blocked
with some or other particle?
Just a thought.
Keep well
Garth
