The other post about a planned treatment-free study reminded me of something I'm looking for and can't find but read once. I know I read a summary of a treatment-free study in Bee Culture several years ago, in one of the sections they do periodically that summarizes new research. I read a summary about a study where they took bees that have Varroa out to an Island, did not treat, and basically watched what happened. What happened was that a lot of bees died the first year or two but started rebounding by year 3. I think this was done in a Scandinavian country.
Anybody have any idea where I can find this?
