Thanks, Bob. No, I was referring to DWV at that time. Used to only see it
when varroa was high. Now see it much more regularly, in the occassional
bee, even when varroa levels are low.
Samples that I have sent to labs don't necessarily find EFB in the yellow
larvae of which I speak. Symptoms look different that what I generally see
for EFB (I've seen EFB when colonies were stressed in early spring, long
before we had varroa in this country, but it would clear up on its own).
What I'm seeing now is more of what I associated with PMS, or what Dr Pettis
and David VanE are currently referring to as "snotty brood." They are not
calling it EFB, either. Both them and I have been seeing snotty brood for
about two years, on opposite coasts of the country.
I can't blame it on pesticides or miticides, since the former are rare in my
colonies, and the latter are absent. There is something else afoot.
