Abstract: | Several alternate hosts were tested for their relative susceptibility to an isolate of Galleria mellonella nuclear polyhedrosis virus. Neonate Trichoplusia ni, Heliothis zea, and Manduca sexta were all susceptible to per oral administration of purified polyhedra. Of the three alternate species tested, T. ni was the most susceptible, and exhibited the most variable mortality response over the dose range tested, while M. sexta was the least susceptible. We believe this represents the first report of a lethal virus infection in a sphingid species, and useful parameters for the successful inoculation of alternate hosts are discussed. |
