Abstract

A long-term study initiated in 1989 at the West Virginia University Forest contrasted the effects of silvicultural treatments on the development of gypsy moth (Lymantria dispar L.) outbreaks and their impacts. The area is a relatively susceptible Quercus spp./mixed hardwood forest. Egg mass densities, survivorship, and mortality from natural enemies differed little between stands that were treated silviculturally and those that were not. However, stands that were thinned had less overstory mortality than unthinned stands despite incurring comparable levels of defoliation.
