>> varroa resistance << concept of my method of the selection on Varroa resistance: offspring of several years not treated colonies with tuning and performance record 1. Year: queens are introduced at each colony 2. Year: colonies are selected on achievement and infestation development 3. Year: the best ones are not entmilbt and come on the selection place  -->  Varroa killer test 4. Year: the best ones come on the resistance place. --> Recent selection --> the best ones are used as breed colonies
