What do you do about the virus and keeping it from spreading or is it too late Walter Ontario>> An individual bee with the virus has had it; all you can do is control the vector, which we know to be varroa in most cases, and hope the colony lasts long enough to raise a new generation of healthy bees. I had three colonies with DWV last October, after a sudden influx od mites from collapsing hives in the area. After a hasty treatment (I had been intending to use oxalic over the New Year), I appear to have saved two. The third, which had the most serious outbreak - a good dozen bees with crumpled wings seen in a rapid inspection, as opposed to two or three in the others - died out in December. I can only assume it was more susceptible, and if so, good riddance. Regards, Robert Brenchley Birmingham UK -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
