Using acoustic technology to reduce bark beetle reproduction
Acoustic 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.
A 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.
The targeted use of biologically relevant sounds disrupts insect behaviors and could be a species-specific, environmentally friendly method of insect management. © 2013 Society of Chemical Industry
