Re: Varroa mites never seem to be much of a problem
joe, you had mentioned having started with feral stock, and breeding in carnolians for more workability.
perhaps the resistance you observe has been brought in by those ferals.
also, it seems intuitive that you would have lots of ferals nearby, lending their drones to mate with your queens.
do the folks you supply with queens continue to have this success with mites?
i would be interested in knowing what the mite levels are in apiaries like yours, (treatment free for years, and few if any losses from mites).
i think that seeing what mite levels are tolerated by such bees would be helpful to establish a goal or benchmark.
would you be willing to sacrifice a few bees next summer to see?
