Bob, I agree. The point was that the threshold can be much lower in
different locations. Depends on the virus present. This was observed in the
US and Canada. Some locations had high Varroa loads and survived, while
others were lower and did not. All depended on the virus. Also, it seems we
have a broader mix of critters than the UK and the mix is not uniform over
both the US and Canada.
