These are very interesting claims, on a par with Lusbys' experience, but AFAIK, without any change of comb or difficult and expensive changes. I recall that back in 1999, at Apimondia in Vancouver, Danny was commenting in a talk he gave, that he had had a few drone colonies that were about to crater with varroa, and had requeened with one of his strains. The colonies had subsequently overcome varroa and recovered without other treatment. I found that remarkable and have mentioned it to others, but no one has had a comment. He did not say that they eliminated varroa, just that they did very well, even after coming very near death. My friends who have several Weaver stocks say that they do carry some detectible varroa, and also that they are pretty hot. They have not had them long enough to say whether it will survive long-term untreated in their Northern locale without succumbing to mites. Has anyone on this llist had any experience with Weavers' queens in this regard? Has anyone been down there to take a look? I should think that, in light of the huge losses that many are suffering, this bears some scrutiny. allen A Beekeeper's Diary: http://www.honeybeeworld.com/diary/ :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
