>From the introducion of the dronemethode:
(perhaps it helps)
Varroa mites propagate in brood cells. Research from the University of
Wageningen (The Netherlands) has shown that the Varroa mites are 12 times more
likely to enter drone cells versus worker cells. Therefore, If a situation is
created wherein all of the mites are on the bees (and not in any brood) it is
possible to catch a high percentage of the mites with a couple of drone cell
brood frames. Capturing mites in broodless hives with drone cell frames is
very effective. A broodless period is essential to this method since the
mites, all on the bees, will be caught in the drone cells. This principle is
used in biotechnical mite control methods.
