Acoustic Studies of Dendroctonus Bark Beetles

The utility of recording, monitoring, and manipulating acoustic signals of destructive bark beetles and some methods of bioassay and analysis related to pheromone research are discussed. J. A. Rudinsky and his research group at Oregon State University utilized particular chirps of males and females to acoustically stimulate pheromone release, for bioassays of odors as possible pheromones, and as indicators of the behavior of beetles hidden under the bark. A summary of the acoustic signals of five species of Dendroctonus, D. pseudotsugae, D. ponderosae, D. brevicomis, D. valens, and D. frontalis, is presented.
