BACKGROUNDAcoustic signals play a critical role in mate choice, species recognition, communication, territoriality, predator escape and prey selection. Bark beetles, which are significant disturbance agents of forests, produce a variety of acoustic signals.
RESULTSA bioacoustic approach to reducing bark beetle reproduction within wood tissues was explored. Playback of modified biological sounds reduced beetle reproductive output, tunneling distance and adult survival....
BACKGROUNDAcoustic 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,...
