Bit of a broad brush there Bob!  What I said was that no studies have found
N ceranae to be correlated with winter losses.

Higes has good data indicating that N ceranae is rough on his Am iberensis
in Spain.

Jerry Bromenshenk found a strong correlation between colony death and N
ceranae in association with a virus.

Frank Eischen has documented reduced honey yields with N ceranae infection.
 The Cards feel that N ceranae is a big problem for them.

What I have said over and over is that the effects of N ceranae infection
are very unclear, and apparently dependent upon environmental factors
(nutrtition, race of bees, climate, or pesticide/miticide exposure) and
perhaps coinfection by other parasites.  Still an enigma, and poorly
understood.

And nothing that you post falls on deaf ears!  I read every one of your
posts carefully!  What I have said several times is that I am very curious
as to why N ceranae appears to be a problem in some operations, such as
yours, but not in others.
