| Popis: | Contents of amino acid and starch, as the two major indispensable nutrients for a wood-destroying beetle, Lyctus brunneus (STEPHENS), were compared between the foods (artificial diet; oak sapwood) and the feces. Although the degrees of utilization by this insect varied considerably among amino acids, the acidic amino acids and those with hydroxyl group were rather preferentially utilized. Starch in the samples was analyzed to obtain the ratio of amylose to amylopectin. The latter that was contained in greater amounts seemed to be more efficiently utilized by the insect. The value of the ratio of consumed quantity of starch to that of amino acids in the oak sapwood was higher than that in the artificial diet, indicating a higher requirement of energy in wood feeding than in diet feeding. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 |
