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.
采用单项选择和多项选择测试来确定宿主植物化学提取物在诱发云杉芽虫幼虫取食中的相对重要性。宿主树木的水溶性成分是最重要的,其中糖和糖苷部分最具刺激性。氨基酸和有机碱部分没有明显的效果。有机酸部分略微抑制取食。
