Strain differences in the indian meal moth,Plodia interpunctella, in response to a granulosis virus

Original Paper


Three strains of the Indian Meal Moth,Plodia interpunctella, were compared in terms of their response to a granulosis virus under different environmental conditions. A significant difference in the relative susceptibilities to the virus of the three laboratory strains was established. Evidence of potential trade-offs with resistance was found in overall fecundity, pupal size and mortality at adult emergence. There was however little evidence that a reduction in resource level led to more trade-offs being apparent. No clear relationship was found between resistance to the lethal effects of the virus and susceptibility to the sublethal effects of the virus.
