> Removing the stress of varroa is often what is needed to keep the hive on
the live side of the tipping point.
I agree with Scott on this. Although I occasionally observe an obviously
virus-immune colony, I'm focusing my breeding efforts upon colonies that
keep varroa under control (selecting for varroa resistance rather than
tolerance). Such colonies thrive in my area without needing other inputs.
