My personal opinion is that the problem is primarily Varroa and
> all else flows from that.
Bill, we had collapses before varroa, so IMO, varroa would be classed as a
secondary contributor. But a damn strong contributor nonetheless.
I've been checking a lot of bees for nosema of late. Hard to find in most
of my yards. But the one place that I can always find it is in the "sick
yard" that I brought all my most varroa infested colonies home to for
experimentation. Could be coincidence, but I'd sure like to see a study as
to whether nosema thrives in varroa-infested colonies. Pete, have you seen
such a study?
