Infectivity of a nuclear polyhedrosis virus isolated from Anagrapha falcifera (Lepidoptera: Noctuidae) against production and postharvest pests and homologous cell lines
Environmental Entomology 22 (5), 1140-1145
Abstract: The nuclear polyhedrosis virus (AfMNPV) isolated from the celery looper, Anagrapha falcifera (Kirby), was tested against six species of production and postharvest lepidopteran pests and four insect cell lines. LC50s in PIB/mm2 were 23.9, 42.2, 47.3, and 510.4, respectively, for raisin moth, Cadra figulilella (Gregson), navel orangeworm, Amyelois transitella (Walker), codling moth, Cydia pomonella (L.), and Indianmeal moth, Plodia interpunctella (Hübner). The almond moth, Cadra cautella (Walker), and the tobacco moth, Ephestia elutella (Hfibner), were not susceptible. Histological examination revealed that hypodermic, fat body, tracheal matrix, midgut epithelium, and Malpighian tubules in all four susceptible species were infected. The Trichoplusia ni cell line TN368 and the P. interpunctella cell line PID2 were permissive to AfMNPV as well as to a contaminant cytoplasmic polyhedrosis virus (CPV). However, two navel orangeworm cell lines, AT10 and AT20, were permissive to the CPV only. Restriction endonuclease analysis showed that the NPV was unchanged after passage through all of these hosts. Probably of greatest significance is that AfMNPV is the first baculovirus reported to be infectious to the navel orangeworm, a major pest of almonds.
