The seasonal phenology of dogwood borer was measured in four apple orchards in Virginia and West Virginia. In contrast with published research, there was no positive correlation between the weekly capture of male moths in pheromone traps and the abundance of fresh pupal cases. There were large differences in the number of dogwood borer males captured in traps baited with different, commercially available pheromone lures. The sex-ratio of dogwood borer moths was recorded, using a novel method based on pupal morphology. The voltinism of dogwood borer infesting apple in the mid-Atlantic region is discussed in relation to trap-catch and pupal case data, and to periodic measurements of the distribution of larval instars.
