Abstract

Observations were made on the flight patterns, sex ratios, and ovipositional activity of Pissodes strobi in Sitka spruce. There is an aggregation of adults on spruce leaders early in the flight season during which sexual maturation and mating take place. Males are more active early in the flight season, while females are more numerous during the latter half of the flight season.
