I remember reading (about 30 years ago) that if one was to put a bit of ammonium
nitrate (now, it has been a .ong tiome and the chemists out there will be able
to tell us if I came up with the correct compound) in your smoker it would
produce laughing gas and put the bees to sleep. When they woke up their memoties
would be blank (well somewhat blank) and one could move the hive a few feet or
yards and they would orient themselves to the new location and never remember
where the hive had been before.
 
This could also be used to sedate(hypnotize) an intansigent hive.
 
On a similiar topicI remember reading in popular science about the same time
that if one attached a transducer the vibrated at a certain frequency it would
stop the bees from moving. I remember discussing this with Adrian Wenner about
this time but we never came up with a test. No, I don't remember the frequency
or decibles needed. My memory is pretty good but not perfect.
