Use of sounds to detect Rhynchophorus ferrugineus

It has been observed that boring larvae of Rhynchophorus ferrugineus (Coleoptera: Curculionidae – EPPO Alert List) continuously create audible sounds while severing vascular bundles of palm trees. The use of a commercial acoustic device, originally developed for the detection of pests of grain, was studied and found useful. Software was then developed to recognize the ‘crunching sounds’ among other recorded sounds. Studies are currently being done to develop a sound profile which will serve as a basis for future instrumental detection of R. ferrugineus within palm trunks and offshoots.
