Interesting point, Gavin. Last year, during the height of CCD, I spoke with
several almond pollinators who left yards of dinks behind (including
myself). We were often surprised when we returned to those yards later in
spring, that the colonies had *miraculously* recovered (no I'm not talking
about faith type miracles).
I closely observed two colonies that were struggling with sacbrood or
sacbrood-like symptoms completely (visually) eliminate the problem, and then
go on to rebound.
None of us were trying to save dinks--we were just leaving what we thought
were going to be deadouts behind. The general consensus was that a good
spring pollen flow allowed the colonies to recover.
Whether these colonies had special genetics, I don't know. Looks more like
a recovery from nutritional stress, or an activation of the antiviral immune
response. I've got more questions than answers!
