Barry asked if anyone is testing open-mated SMR stock for Varroa resistance without also using chemicals.  Barry, I am reasonably certain that Kirk Webster is doing just that.  He is not on this list, but I believe he is glad to talk about the subject and his results...which are still preliminary.

If you do not know how to contact him, contact me privately and I will provide details.
