Beech Bark Disease Complex

  • Ervin H. Barnes


This is a story of ecological succession—of interrelationships between a fungus and an insect, and the secondary roles played by other fungi and other insects. The disease, or more properly the disease complex, occurs on the American beech in the Northeastern United States and the Maritime provinces of Canada. The beech scale, Cryptococcus fagi, feeds on the bark (Fig. 31-1B) and the fungus, Nectria coccinea var.
