Rhynchophorus Palm Weevil Sounds
Rhynchophorus ferrugineus is an important pest of palm trees in Southeast Asia, the Middle East, and Southern Europe, and has been found recently in the Southern Caribbean region. R. cruentatus is a pest of ornamental palms in Florida. The larvae of these pests feed undetected inside the tree trunk, but they can be detected using acoustic technology, which enables pest managers to identify and treat infested trees.
