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.
