摘　　要：光肩星天牛产卵量和卵孵化率与成虫补充营养的好坏有直接的关系。本文通过天牛成虫用不同食料补充营养后 ,成虫产卵量和卵孵化率有明显差异 ,说明了在成虫补充营养阶段 ,用不同寄主植物的嫩枝和叶喂饲天牛成虫 ,使成虫取得了足够的营养后 ,其产卵量和卵孵化率有显著增加。椴树科植物对天牛既有一定的引诱作用 ,且又能抑制其卵的孵化及幼虫的生长发育。糖槭是天牛最喜食的树种 ,但在经过糖槭的枝叶喂饲后 ,天牛成虫在椴树上也能生长到 2龄后就全部死亡。这就为在林业生产中在树种的搭配上提出了更高的要求 ,在天然次生林中 ,只要没有天牛特别喜食的树种存在 。There is direct relation among amount of spawned egg, hatchability of egg of Anolophora glabripennis (Motsch.) and replenishment of nutrition. After replenishing nutrition for Anolophora glabripennis (Motsch.) adults with different food, there is evident difference between amount of spawned egg and hatchability of egg of adults. It shows that amount of spawned egg and hatchability of egg of adults can obviously increase after replenishing enough nutrition by feeding adults with different epicormic branch and leaves in period of repenishment of nutrition. Plants of Tilia L. not only can lure Anolophora glabripennis (Motsch.), but also can inhibit its incubation of egg and growth of larval. Acer saccharum Marsh. is the best favorite tree species for Anolophora glabripennis  (Motsch.). By feeding with branches and leaves of Acer saccharum Marsh, all the Anolophora glabripennis (Motsch.) adults will die at two years old on Tilia L. trees. In natural secondary forest, plants of Tilia L. can give full play to lure Anolophora glabripennis (Motsch.) if there isn't other tree species that is specially favorite to eat by Anolophora glabripennis (Motsch.).
