DescriptionNucleopolyhedrosis virus (NPV) of the gypsy moth was fed to three mammalian predators of the insect: the white-footed mouse, the short-tailed shrew, and the Virginia opposum in the form of NPV-infected 5th instar gypsy moth larvae, polyhedral inclusion bodies (PIB's) mixed in dog food and PIB's mixed in a standard spray formulation. The total amount of NPV consumed by each treated mouse and shrew was equivalent to more than a 40-ha exposure for a 7Okg person, assuming the NPV was applied at the rate of 5.0 x 1011 PIB's/ha. Analyses of general body condition, weight, and reproductive efficiency, as well as necropsy and microscopic examination of tissues, indicated that the ingestion of NPV had no short-term effect on these predators of the gypsy moth.
