| 摘 要： | 为探索松墨天牛取食对林木的分解作用,本文通过对松墨天牛幼虫及成虫取食量的测定,寄主云南松韧皮组织及松墨天牛幼虫排泄物成分对比分析,并与资源利用相同的木材微生物分解能力进行对比,阐明了松墨天牛作为分解者的重要分解作用。研究表明,松墨天牛幼虫期(约为55 d)取食分解林木生物量平均为12.42 g(24.40 cm3),成虫期取食分解林木生物量平均为12.87 g(25.28 cm3);松墨天牛幼虫对糖类物质的利用度很高,具有较强的纤维分解利用能力,取食分解后总糖减少83.58%,粗纤维减少23.87%,1头松墨天牛幼虫期分解的林木粗纤维质量为1.93 g,分解利用率为0.008 g.d-1。松墨天牛对林木的分解证明,天牛作为一种重要的林木分解的先驱者,可以分解林木,更重要的是松墨天牛攻击亚健康林木,为微生物分解林木提供了容易入侵的途径,加速了亚健康林木的分解与循环,在森林生态系统物质分解与循环中具有重要的促进作用。
