Bark beetles combine long-range chemical with short-range acoustic signaling

Evidence

It is evident that bark beetles use either chemical and acoustic signals to regulate aggression, attachment on host trees, courtship, mating behavior, and population density regulation. The chemical signals seem to be used for communicating at a distance and the acoustic signal for short-distance communication. In the complex behavior of this species chemical and acoustic cues are intensively utilized, although little information is yet available on the hearing organ mechanisms. — Almo Farina, Soundscape Ecology, 788
