I have a question I would like to toss out to the board,


Quote from private conversation related to New Zealand project>>Their 
selection 
process was along the same lines as Harbo,uncapping cells in the later 
stages of development and counting the number of cells that had no 
reproducing mites,breeding up from these until they reached about 80% non 
reproducing. 

>>they don't know what causes the mites to be 
sterile 


Does anyone have any theory on how the bees are able to supress the mites 
ability to reproduce? 

Thanks
