Abstract

The recent black-headed budworm outbreak on the Queen Charlotte Islands is the fourth recorded association between budworm trends and weather. The decrease in this instance was associated with a prolonged period of cold, wet weather which retarded larval feeding and development, resulting in heavy larval mortality. The observations strengthen the previous associations observed between weather and the rise and fall of black-headed budworm populations.
