Yes, I should have mentioned that one--thanks! In general, it appears that
with mellifera and cerana kept in the same area, that cerana has less virus
prevalence.

The recent study by Page suggests that self sacrifice is due to an
apoptosis-like response to wounding alone--not requiring infection by a
virus. I write about the difference in an article in the cue. I find the
subject very interesting, and something that is very promising for breeding
mite resistance via what I call "intolerance."
BTW, apologies to all for getting so behind on posting my articles to the
web. I spend Jan 1st fulfilling a New Year's resolution, and sent 17
articles to my web tech for posting. I'll send notification once they're
up.
