Abstract

Gypsy moth has affected pine-hardwood mixtures, especially oak-pine stands, since the late 1800's. Several old and new studies on impacts in mixed stands are reviewed. When pines are heavily defoliated, considerable growth loss and mortality can occur. Mortality is heaviest in understory white pine trees, Impact information is used to suggest silvicultural management actions to minimize damage in northern mixed stands. Suggestions for pre-infestation treatments in southern mixed stands are made.
