Abstract

American beech trees that were free of beech bark disease in forests long-affected by beech bark disease were challenged with C. fagisuga using the 'foam' technique. Trees were resistant: no insects reached maturity. In Nova Scotia, 12-15 disease-free trees per hectare occurred in the stands examined. Many of these trees occurred in groups.
