| 摘 要： | 研究表明,松毛虫的代谢能主要来源于脂肪。油松与黄栌或槲栎混交后,油松叶中粗脂肪、全糖含量减少,C、N比值下降。取食混交林针叶的松毛虫,其幼虫对食物的消化利用率较取食纯林的减少,幼虫体重增长率、化蛹率及繁殖力也都相应下降。

| Abstract: | The study shows that the metabolic energy of Dendrolimus is originated from fat.When Pinus tabulaeformis is mixed with Cotinus coggygria or Quencus aliena, its leavescontain less crude fat and total sugar, and their C/N ratio is lowered.Because Dendrolimus feeds on pine needles in the mixed forest, the digestion coefficient.weight increment, pupation rate and reproduction capacity of its larvae are all decreased comparing with those in pure forest. |
