Abstract:

Heavy infestations of gypsy moth (Lymantria dispar L.) in Rhode Island forests caused greatest defoliation and mortality in oaks, with white oak (Quercus alba L.) most affected. In mixed oak stands, where mortality was greatest, loss for the period 1972 to 1975 was 17.4 percent of the basal area present in 1972, or roughly double the loss in a nondefoliated control area. Defoliation reduced radial growth of oaks 32 percent in mixed oak and oak-pine stands, and 40 percent in a mixed hardwood stand.
