GEOGRAPHIC VARIATION IN RESISTANCE TO WHITE PINE WEEVIL (PISSODES STROBI) (COLEOPTERA: CURCULIONIDAE) BY EASTERN WHITE PINE (PINUS STROBUS)
Published online by Cambridge University Press: 31 May 2012
Abstract
Weevil damage on 12 sources of eastern white pine was measured. Differences between sources at age 13 were significant, but all sources were heavily weeviled. It is doubtful that sources resistant to the white pine weevil will be located.
