Relative susceptibility of heliothis subflexa lepidoptera noctuidae and other species of heliothis to nonoccluded baculovirus heliothis



Relative susceptibility of heliothis subflexa lepidoptera noctuidae and other species of heliothis to nonoccluded baculovirus heliothis



Annals of the Entomological Society of America 78(6): 740-743



THe LC50 of nonoccluded virus (NOV) of a single-embedded, nuclear polyhedrosis virus, Baculovirus heliothis, fed to Heliothis virescens was 4.5 plaque-forming units (PFU)/cm2. Larvae of Heliothis subflexa, based upon equivalent mortality, were about 1,000-fold less susceptible to the Nov of B. heliothis than were larvae of H. virescens. The LC50 of intrahemocoelically injected NOV of B. heliothis to H. subflexa, H. virescens, or H. zea was 11.3., 3.4, and 2.6 PFU per larva, respectively. Gut juice from either H. subflexa or H. virescens had no antiviral effect on activity of NOV of B. heliothis. Although larvae of H. subflexa are ca. 1,000-fold less susceptible than H. Virescens when fed NOV, they were only 3- to 4-fold less susceptible when injected with NOV. It is concluded that the lack of susceptibility of H. subflexa to B. heliothis is at midgut epithelial cells and may be due to differential virion absorption at the membrane, failure to penetrate, uncoat, integrate, or replicate in epithelial cells, or failure of virions to be released into the hemocoel.
