Almost every drone brood cell exhibited multiple occupation with mites, but they could not produce more offspring than mother mites were there. But on this comb there were only about 80 drone brood cells present, on which all the mites were distributed. Then I analyzed another brood comb on which much more drone brood was created, approximately 200 cells per comb. And there I found many unoccupied drone brood cells and those that were occupied, showed much less Varroa mites than on the first brood comb. This shows once again how important it is to teach the bees again to create the correct amount of drone brood on each comb. This colony is also a survivor colony and was never treated and never the queen was replaced.
