Abstract

A scale insect, tentatively identified as Xylococculus betulae (Perg.) Morrison, is responsible for one type of bark roughening that is commonly seen on American beech (Fagus grandifolia Ehrh.) trees in certain areas of New England. The insect has also been found on paper birch (Betula papyrifera Marsh.) and yellow birch (B. allegheniensis Britton).
