I know my question sounded a bit crazy but sometimes you get a new revelation when you look at the backside of the moon -- aka swarm. What apparently is becoming clear though, that swarming is fairly independent of the status of the residing or emerging queen. It's not like the queen is cracking a whip and encouraging her court to work like crazy so they can leave. Apparently, it is more the environmental factors that boost 100% swarm success - good food stores, good health, strong numbers, small space and older but not failing queen.
I am going to leave the discussion about genetically predisposed swarming tendencies i.e africanized versus european genetics out of the mix because it muddles up things but these genetics may also be rooted in environmental factors.
Just removing a small number of frames with the queen and most of the swarm cells apparently may not extinguish the swarm fever of a strong colony. Does it delay the swarm date though? A swarm wouldn't emerge without a queen, wouldn't it. As soon as the first virgin queen emerges the "after swarm" can take off. If the primary swarm would have left with the old queen, the swarm date may have been eight days earlier when the first swarm cell was capped, right?
Buying yourself some time by encouraging swarming in the short term but delaying the swarm date, may be part of good overall management.
