How does an informed minority of scouts guide a honeybee swarm as it flies to its new home?

Article Abstract:

Experiments on honeybee swarms provide support for the vision hypothesis rather than the olfaction hypothesis with regard to scout navigation. Flights of unaltered swarms were compared with those for which the members' Nasanov glands were closed off, to rule out the effect of pheromones.
