Dr. Peter Teal, USDA ARS has investigated mite attraction.  Questing mites
are strongly attracted to the pheromones secreted by drone larvae shortly
prior to being capped.  When another species reacts to a pheromone, it is
called a kairomonal response.

On the mite's native host, A cerana, pheromones secreted by worker larvae
do not normally initiate ovulation in the mite--it takes the drone
pheromone (kairomone) to do so.
