'Yes, data exist.  Generally only one foundress per cell until mite
infestation rate climbs to a high level.'


Could you point us to this data, Randy, please?  Because, as I outlined in an earlier thread, I have been looking at drone brood in some detail.  The mite foundresses were congregating in some areas of the frame.  There were large areas with no mites, and some areas with lots of mites.  This means more than two foundresses/cell...up to four(!), but not in all cells...most drones were mite-free.  I observed this in hives that were not collapsing, that I'm currently packing for winter.  My observations are anecdotal.


Thanks.


Christina
