Abstract
Abstract Eighty-six 19-year-old eastern white pine trees from a rangewide collection growing in a plantation in southern Maine were analyzed for oleoresin chemical composition and viscosity. Qualitative and quantitative variations in monoterpenes and resin acids were examined for possible relationships between geographic source and resistance to the white-pine weevil. Geographic variation patterns were found for α-pinene, 3-carene, and terpinoline, but not for the resin acids. Oleoresin viscosity did not differ among provenances. Scores for resistance to the white-pine weevil were compared for resistance and the oleoresin composition and viscosity. These indicated that no relationship exists between these traits and resistance to the insect. Forest Sci. 25:175-183.
