Acoustic technology is a potential tool to protect wood materials and eventually live trees from colonization by bark beetles. Bark beetles such as the southern pine beetle Dendroctonus frontalis, western pine beetle D. brevicomis and pine engraver Ips pini (Coleoptera: Curculionidae) use chemical and acoustic cues to communicate and to locate potential mates and host trees. In this study, the efficacy of sound treatments on D. frontalis, D. brevicomis and I. pini entry into tree materials was tested.
Acoustic treatments significantly influenced whether beetles entered pine logs in the laboratory. Playback of artificial sounds reduced D. brevicomis entry into logs, and playback of stress call sounds reduced D. frontalis entry into logs. Sound treatments had no effect on I. pini entry into logs.
The reduction in bark beetle entry into logs using particular acoustic treatments indicates that sound could be used as a viable management tool.
声学技术是一种潜在的工具，可用于保护木材以及最终保护活树免受树皮甲虫的侵害。诸如南方松甲虫（Dendroctonus frontalis）、西部松甲虫（D. brevicomis）和松树小蠹（Ips pini，鞘翅目：象甲科）等树皮甲虫利用化学和声学信号进行交流，并定位潜在的配偶和寄主树。在本研究中，测试了声音处理对南方松甲虫、西部松甲虫和松树小蠹进入树木材料的效果。
声学处理显著影响了甲虫在实验室中是否进入松木原木。播放人工声音减少了西部松甲虫进入原木的情况，而播放应激叫声减少了南方松甲虫进入原木的情况。声音处理对松树小蠹进入原木没有影响。
使用特定声学处理减少树皮甲虫进入原木的情况表明，声音可以用作一种可行的管理工具。
