Abstract
AbstractA survey of the sucking insect fauna of the birches has been conducted in the Maritime Provinces, and a check-list of 75 species of Homoptera and Hemiptera, with tabulated data on host relationships, is presented. The bulk of the population on any of the three birches (Betula alleghaniensis Britt., B. papyrifera Marsh., and B. populifolia Marsh.) has three major components: the Oncopsis leafhoppers, Psylla striata Patch, and the phyllaphidine aphids. The many other species present occur at much lower density but often have a broader dependence upon other hosts. The main homopterous families and their relationships to birch and the forest communities are discussed.
