Exactly!  Something changed.  But in my case I can't blame it on pesticides
or miticide buildup, so yes, that leaves as the most likely suspects cell
phones and feeding sugar syrup (just kidding).  That leaves N ceranae and
novel virus strains.

I would have liked to have seen that (from scientific interest).  Perhaps
what I'm seeing in the sudden deaths of several thousand bees in the
occasional hive.

I'm currently seeing in my operation the occasional hive with a raging
virus? epidemic in the brood--generally associated with mite levels above
5%.

This is my experience, too!
