A nuclear polyhedrosis virus isolated from a larval population of the Forest Tent Caterpillar, Malacosoma disstria, was fed to first- and second-instar gypsy moth, Lymantria dispar, larvae where it caused tissue damage and low mortality. Growth of most individuals was retarded until they reached the last instar when recovery of the growth loss was rapid and nearly complete. The infected individuals reached the adult stage 3 to 4 days later than the controls; otherwise they appeared normal.
