Gypsy moth, Lymantria dispar L., nuclear polyhedrosis virus (NPV) was applied by ground equipment at the rate of 2.5 × 1012 polyhedral inclusion bodies (PIB's) per ha to the lower half of ten trees (per plot) in homeowner-sized plots in Hardford and Baltimore Counties, MD, in 1986. A laboratory bioassay of field collected larvae indicated that a highly significant (P < 0.001) increase in early season mortality of gypsy moth larvae due to NPV occurred in the zone of spray, compared to mortality in a similar foliage zone in untreated plots. Late-season treatment effects varied greatly, in apparent response to significant (P < 0.05) area effects.
