Publication Series: Scientific Journal (JRNL)

Description: Resident populations of white-footed mice, Peromyscus leucopus Rafinesque, red-backed voles, Clethrionomys gapperi Vigers, opossums, Didelphis marsupialis L., chipmunks, Tamias striatus L., and raccoons, Procyon lotor L., were evaluated to detect any short term effects from aerial applications of the nucleopolyhedrosis virus (NPV) of the gypsy moth. NPV in 2 formulations was sprayed on woodland plots in central Pennsylvania at the rate of 2.5 x 1012 polyhedral Inclusion bodies (PIB)/ha. Comparisons of prespray and postspray censuses of whIte-footed mIce and red-backed voles in control and treated plots revealed no changes in populations or body weight that could be attributed to NPV treatments. Data from 47 caged and 250 free-living mammals showed no significant differences in organ and tissue weights, hematological values or necropsy and histopathological rankings between control and treated mammals when sample sizes were large and mean total weIght between groups similar. It was concluded that aerial applications of NPV at 2.5 x 1012 PIB/ha caused no short term adverse effects to those mammals that either contacted NPV during it's application or subsequently fed on NPV infected gypsy moths or other NPV-contaminated food sources.
