So, for how long does a varroa mite stay on an adult bee?
That Varroa mite you see riding on a worker is not necessarily looking for a brood cell immediately.
When brood is available, female Varroa usually spend several days on adult bees before entering another cell, with commonly cited estimates around 4 to 11 days.
Other research describes the period more broadly as anywhere from 1 to 10 days or even longer, so there is definitely no fixed countdown.
And we should probably stop calling this simply the phoretic phase.
Scientists increasingly call it the dispersal phase because the mite is not just hitchhiking on the bee.
She is feeding on the adult bee while being transported through the brood nest, usually preferring young nurse bees that constantly visit larvae.
Who would have thought?
That choice is brilliant from the parasite's perspective.
A nurse bee basically becomes transportation directly toward the next generation of suitable brood.
This should clarify the question.
