| Abstract: | Single-choice and three-choice tests were used to determine the relative importance of host-plant chemical extracts in eliciting feeding by spruce bud worm larvae. Water-soluble components of the host trees are the most important and, of these, the sugar and glycoside fractions are the most stimulating. The amino acid and organic base fractions have no apparent effect. The organic acid fractions deter feeding slightly.Lepidoptera: Tortricidae.Supported by the National Sciences and Engineering Research Council of Canada, Operating Grant No. A9723 to P.J.A. |
