两种星天牛幼虫对不同树种的食性研究

A Study on the Feeding Habits of the Larvae of Two Species of Longicorn (Anoplophora) to Different Tree Species

用２３种杨树（含品系）和２４种其他常见树种，对光肩星天牛和黄斑星天牛幼虫进行饲养观察。参试的４７种树种均可被取食。天牛幼虫对各树种树皮、木质部的取食量差异明显，对不少树种表现为被迫取食。不同树种对天牛幼虫的生长发育影响十分显著。

The larvae of Anoplophora nobilis Ganglbauer and A. glabripennis Motsch. were bred with twenty three species of poplar and twenty four other species of regular tree and their feeding habits were observed.All the forty seven species of tree could be fed by the larvae. The amount of bark being eaten differed obviously from that of xylem by the larvae of the two species of longicorn beetle. For some tree species,they were fed under stress.The growth and development of longicorn larvae were obviously affected by different tree species.
