Abstract
Pine weevils (Hylobius abietis) fed less on bark of lodgepole pine (Pinus c ontorta) than on bark of Scots pine (P. sylvestris). Two pine weevil anfife edants, ethyl trans-cinnamate and ethyl 2,3-dibromo-3-phenyl-propanoate, we re isolated from bark of lodgepole pine. These two compounds significantly reduced pine weevil feeding in a laboratory bioassay. In field assays, the second compound significantly decreased pine weevil damage on planted seedl ings. Ethyl 2,3-dibromo-3-phenylpropanoate has not previously been reported as a natural product.
