Brown marmorated stink bug (BMSB) trap capture data from 2017 to 2021 in different ecoregions of North Carolina were examined and used as field validation testing of degree-day phenological models. Season-long trap capture was collected in the Mountains, Piedmont, and Coastal Plains of NC and temperatures (and therefore growing degree-days) varied among the three ecoregions. Trap captures and phenology were examined for differences among regions. Valid, empirically-based models are important for improved prediction of phenological events of this invasive pest. For example, predictions of timing of adult eclosion is key for improved BMSB management programs and optimizing insecticide application or biological control tactics.
