I've seen the same in my colonies at FAR lower levels than Delaplane 
recommends.  At the first sign of virus, thresholds go out the window.

Judy Chen's presentation at CSBA showed how viruses are found in honey, 
wax, and pollen.  Good thing to keep in mind.  But Bob, I haven't seen a 
case of what I'd call PMS in quite a few years.  Curlywing collapse, 
yes, but not full-blown PMS.  Are you others seeing it?
