I recall, that at Apimondia in Vancouver, Danny was saying in a public
address that he had noticed that some of his lines were able to overcome
varroa.  He said, in particular, that he had a drone colony that was badly
infested and had requeened it, then let it go.  He had been pleased later to
observe that it had recovered nicely with no treatment.

That was a few years ago.  At the time, such reports were very unusual, and
Aaron and I looked at one another and wondered.

There are a lot of factors that combine to add up into resistance.  Some are
environmental, some are related to management, and the balance are in the
bees themselves.  Bees that exhibit tolerance under some conditions may be
overwhelmed in others.

Test, test, test.
