Joel,Interesting observations in NWC.
 
Just started looking at hygienic behavior as a defense against V. Though
this will probably take several mech. of defense to knock, as well as some
time. Please be patient.
 
We've been concentrating efforts on Tracheal mites up to this point. Counts
are almost undetectable in the breeders coming out of winter this year with
no treatment.
