"Capped drone brood removal is a varroa mite control technique that
reduces the need for chemical treatments."
Do varroa mites actually prefer drone larva? Or do they not care and it
is just more effective to remove drone brood because from each cell
there will be two or three mite offspring compared to one from a worker
bee cell. But if the mites do seek out drone larva, how do they know
where to go? Is it the larger cell size or a scent that guides them?
