The gypsy moth (Porthetria dispar, L.) is now a problem in New Jersey. Repeated defoliations of oaks (Quercus spp.) began in the 1,350-acre Morristown National Historical Park in 1967. Within two years, 28 percent of the oaks were dead. Most vulnerable to loss were: northern red oak (Q. rubra), white oak (Q. alba), and scarlet oak (Q. coccinea) between 6 and 12 inches dbh and trees in excess of 26 inches. Where oaks predominate and no insecticides are applied, salvage logging must begin after the second consecutive year of heavy defoliation.
