swarm lure vs "kill the invader queen"

[FRAMEshift]

Does anyone understand how this works?  If you pinch a queen and put her in alcohol, this works as a lure to attract swarms.  But if instead of pinching her, you put that same queen into an existing hive, the bees would probably kill her.

It's pretty clear that bees can tell one queen from another since they kill intruders and protect their own queen.  Why then is the pheromone of a foreign queen attractive to a swarm?  You would think they would be repelled if they thought a space was occupied by a queen not their own.  Do swarms just follow any queen scent they can find?

I would think they can tell a fresh scent from an old one. A swarm will occupy any void where there has been bees before.

A swarm will hit the same branch where a swarm was parked earlier.   The smell was still there.  Something else to ponder.

I never pinch them.  I just drop her in the alcohol.  A swarm doesn't know one queen from another.  It is attracted to QMP.

Actually, they might, but probably is stretching it.   If you put her at the entrance they will.

There is a school of thought, led by none other than Brother Adam, that they CANNOT tell their queen from another, but they can tell a queen who is currently laying from one that's been in a cage a few days.

Swarms are chaos.  They often swarm at the same time as other hives and obviously can't tell which is their cluster by the way the clusters grow and shrink.

>You would think they would be repelled if they thought a space was occupied by a queen not their own.

But they can't tell.

>  Do swarms just follow any queen scent they can find?

Yes.  They do.

There are probably times when the growth of a hive is limited by the rate the queen can lay.  Have you tried adding a second laying queen to a fast growing hive to see if it would build even faster?  Seems like that might really make a difference during spring buildup.

I had 5 or 7 queens in alcohol and it has no effect on swarms. I throw away that stuff. I Tried it on several swarms.

I had a Russian lure greese which atracted very well swarm.
One swarm dropped it down from 15 m high level.

Then I have used a French spray. No effect. it think that it  evaporate in sun shine too quickly. A  greese keeps its aroma longer.

Lemongrass essential oil alone works better than the queen juice alone, but the combination of the two is pretty much irresistible to the bees.
