Interpretive Summary:

Technical Abstract: Much of the damage caused by red palm weevil larvae to date palms, ornamental palms, and palm offshoots could be mitigated by early detection and treatment of infestations. Acoustic technology has potential to enable early detection, but the short, high-frequency sound impulses produced by red palm weevil larvae can be difficult to distinguish from certain similar sounds produced by other insects or small animals, or by wind-induced tapping noises. Considerable research has been conducted to develop instruments and signal processing software that selectively amplify insect-produced sounds and identify signal features that distinguish sounds produced by a particular target insect from those produced by other causes. Progress has been made in identifying unique spectral and temporal patterns in the sounds produced by larvae during movement and feeding activities. This report describes some of the new instrumentation and signal analyses available for early, reliable detection of red palm weevil larvae in groves and greenhouses.
