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.

The beet armyworm (Hübner), a global pest, feeds on and affects a wide range of crops. Its long-distance migration with the East Asian monsoon frequently causes large-scale outbreaks in East and Southeast Asia. This pest mainly breeds in tropical regions in the winter season every year; however, few studies have investigated associations with its population movements in this region.

Recent changes in climate and environments have promoted the range expansion of insect pests of tropical and subtropical origins into temperate regions. For more accurate and faster risk assessment of this expansion, we developed a novel indicator to link a physiologically derived parameter of chilling injury with the survival of insect populations in nature by using two insects, Spodoptera frugiperda and Cicadulina bipunctata with tropical and subtropical origins, and one cool-adapted insect, Laodelphax striatellus. The parameter derived from a proportional increment in the time to 99.

Seasonal polyphenism enables organisms to adapt to environmental challenges by increasing phenotypic diversity. exhibits remarkable seasonal polyphenism, specifically in the form of summer-form and winter-form, which have distinct morphological phenotypes. Previous research has shown that low temperature and the temperature receptor regulate the transition from summer-form to winter-form in by impacting cuticle content and thickness.
