| 摘 要： | 小蠹虫是世界性大害虫 ,特别是对松树危害极大 ,猖獗时常可造成林木成片枯死。其生活隐蔽 ,繁殖迅速 ,在造成林木枯萎前不易被人们发现。但衰弱木及某些种类的性外激素对其有很强的吸引力 ,诱集效果显著 ,可作为重要的监测手段。该虫主要发生在立地条件差、林地卫生条件不好或由其它各种原因导致树木生长衰弱的林分。因此 ,其预防措施主要是选用良种壮苗 ,进行适地适树营造混交林 ;加强监测 ,及时消灭虫源基地。其防治策略及研究发展方向应向以生态管理为基础 ,以生物防治为主导的综合治理方向发展 ,方能达到可持续控制小蠹虫对林木的危害

| Abstract: | Bark beetles, which are worldwide pests, do serious harm especially to pine trees and often make the whole mass of trees die when they were epidemic They are unlikely to be found before the trees wilt due to their hidden life and rapid reproduction But they are strongly abstracted and trapped by weaken woods and some kinds of pheromone Thus this could be an important monitoring measures These pests mainly occur in weakly growing stand due to unsuitalle site bad stand health or other reasons So the main precaution measure should be to plant strong seedlings of excellent species as fixed forest with proper tree species in proper site and to strengthen monitoring so as to eliminate their original site in time Integrated management based on ecological management and led by biological control should be the control strategy and developing direction for study Thus injure of bark beetles to forest could be sustainablely controlled |
