Vertical transmission occurs when honey bee colonies cast reproductive swarms, and the phoretic mites travel upon the swarming bees to the new nest site. It is however the best measure of how your bees and you are doing in resisting/tolerating mites. The phoretic stage is important for mites to transfer horizontally to other colonies, by being accidentally dropped onto flowers and then picked up by other foragers (this probably does happen, but we do not know the actual probability), by mite-carrying bees drifting to another colony, or finally by bees robbing a colony dying from mite .
