Our objectives were to predict pheromone-trap catches and oviposition of blackheaded fireworm, Rhopobota naevana (Hubner), on commercial cranberry farms in Wisconsin, Washington, Oregon, and British Columbia and to model oviposition in Wisconsin. Rea

Phenology of blackheaded fireworm larvae, Rhopobota naevana (Hubner), was simulated with developmental rate-summation models. The relationship between temperature and median developmental rates of third instars and pupae were determined by using line
