 Is it the case that your bees have relatively few drone brood in spring and
many in summer?  A colony holding Varroa numbers stable would have a high
proportion of drone brood infested when there are few, and a low proportion
when there are many simply because there is an overabundance of brood for
them then...


thanks Gavin, the thought had crossed my mind, but I will dig into to it a
little more and see if i can see any patterns developing with drone (varroa)
load being a function of drone/worker brood ratio...or even a springtime
exodus of the varroa to the drone cells from the workers..
