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.
冬季蛾，Operophtera brumata，最初来自欧洲，已入侵马萨诸塞州东部，导致该地区许多落叶树种和各种作物植物广泛落叶和受损。我们通过 PCR 扩增杆状病毒多角体基因的 482 bp 区域，从马萨诸塞州野外采集的冬季蛾幼虫中鉴定出冬季蛾核多角体病毒（OpbuNPV）。在未能羽化的冬季蛾蛹中也检测到了病毒序列，这表明这些昆虫可能因病毒感染而死亡。这是在美国冬季蛾种群中首次报告 OpbuNPV。
