Abstract: | Winter moth, Operophtera brumata, originally from Europe, has invaded eastern Massachusetts causing widespread defoliation and damage to many deciduous tree species and a variety of crop plants in the infested area. We identified O. brumata nucleopolyhedrovirus (OpbuNPV) in winter moth larvae collected from field sites in Massachusetts by using PCR to amplify a 482 bp region of the baculovirus polyhedrin gene. Viral sequences were also detected in winter moth pupae that failed to emerge, suggesting that these insects may have died as a result of viral infection. This represents the first report of OpbuNPV in winter moth populations in the US. |
