>Right, but bear in mind the study in Europe is with native bees, which have taken thousands of years to become "locally adapted." I don't think it can happen in a few decades and I don't think it is likely to happen in the USA where the bees are constantly moved around. 

>Besides, there are no native honey bees. The best one could do would be to use a bee which is adapted to a similar climate region as where one resides. Which in my case, Russians would be best in our climate. I have never tried them, but I probably should. 

The closest thing we have to native bees would be the unmanaged M mitotypes found by Deb Delaney and others, mostly in southern Appalachia.  These are traced back to the first amm brought in 400 years ago from western Europe, and have managed to make it through the introduction of varroa here in fine style.
