While both bucket traps (such as this one) and Picusan cone traps have been used for capturing the palm weevil Rhynchophorus palmarum, new research by a team at the University of California, Riverside, says the cone traps are far more effective—capturing 89 percent of weevils that entered, versus just 18 percent for bucket traps.
