Interinstar susceptibility of the fall webworm, Hyphantria cunea, to its nucleopolyhedrosis and granulosis viruses
Abstract
Comparative interinstar susceptibility of the fall webworm, Hyphantria cunea, to granulosis and nucleopolyhedrosis viruses was quantitated. As the larvae matured, susceptibility to either baculovirus preparation decreased. Mortality data converted to a dose per milligram body weight basis demonstrated that this decrease in susceptibility was only in part due to the difference in weight of the larvae tested. Lethal time data showed that incubation time for either baculovirus was dependent on the age of the larvae and the dose of virus assayed. A difference in interinstar susceptibility was observed between the granulosis virus and nucleopolyhedrosis virus.
