摘要:

白蜡窄吉丁、萧氏松茎象、光肩星天牛、黄斑星天牛、云斑天牛和桑天牛等林业害虫均为我国本地林业生态系统中的昆虫种类,在北美白蜡树、北美松树和北美黑杨派杨树等外来树种引入和大量栽培之前,一直没有形成严重的危害,以至于白蜡窄吉丁和萧氏松茎象都没有引起人们的关注。这些重要林业害虫在我国的发生都是伴随着敏感外来树种的引进和大量不合理的种植而逐渐严重起来的。本文对外来树种的引进与本地林业虫害的发生之间的关系进行了分析,提出了外来树种的不合理引进可能诱发本地林业新虫害的观点,并对其发生机理以及相应的研究和治理对策进行了讨论。

Abstract:

Agrilus planipennis Fairmair, Hylobitelus xiaoi Zhang, Anoplophora glabripennis (Hotsch),  Anoplophora nobilis (Ganglbauer), Batocera horsfieldi Hope and Apriona germari Hope are indigenous insect species frequently encountered in local forest ecosystems in China with no significant damages recorded. As a result, little attention had been directed to such species as A. planipennis and H. xiaoi in the past. Damages caused by these species to our forests in recently years,  however, become more serious due to the introduction and wide utilization of North America species of ash, pine and popular in forest plantations. The outbreaks of these indigenous species occurred in conjunction with the introduction of sensitive exotic tree species species and ill-advised expansion over large areas. Based on the correlation between the outbreaks of indigenous insect species and exotic tree species, this paper further confirmed the hypothesis of induced outbreak of indigenous insect species by exotic tree species and discussed its mechanism and management countermeasures.
