Three species of birds and 5 species of mammals were captured in the wild from 2 plots in which mortality from naturally occurring nucleopolyhedrosis virus (NPV) among gypsy moth, Lymantria dispar (L.), larvae was 15 % and 70 %. Bioassays of intestinal contents showed that blue jays, Cyanocitta cristata (L.), towhees, Pipilo erythrophthalmus (L.), white-footed mice, Peromyscus leucopus Rafinesque), redback voles, Clethrionomys gapperi (Vigers), raccoons, Procyon lotor (L.), and a chipmunk, Tamias striatus (L.), contained infectious NPV (polyhedra) in their alimentary tracts, whereas robins, Turdus migratorius (L.), and masked shrews, Sorex cinereus (Kerr), did not. Comparisons among mice and voles indicated that those collected from the plot in which the NPV mortality was greatest (70 %) contained the most virus. We concluded that birds and mammals can passively transport infectious gypsy moth NPV in the wild.
