Identification of a nucleopolyhedrovirus in winter moth populations from Massachusetts

J Invertebr Pathol. 2011 Nov;108(3):217-9. doi: 10.1016/j.jip.2011.08.005. Epub 2011 Aug 27.


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.
