Research Reports: Trap for Capturing and Retaining Rhynchophorus Cruentatus(Coleoptera: Curculionidae) Adults Using Sabal Palmetto as Bait

Freshly felled cabbage palmettos, Sabal palmetto (Walter), were attractive to Rhynchophorus cruentatus (Fabricius) adults for at least 35 d. Chopped S. palmetto crown tissue placed in 19-liter plastic buckets attracted weevils, but for less than 35 d. Captured weevils did not always remain in the harborage of chopped tissue and were able to escape from uncovered buckets. Baffles constructed from 5 cm long polyvinyl chloride tubes glued together longitudinally and placed over bucket openings effectively prevented escape of R. cruentatus adults. Buckets covered by baffles and baited with S. palm... Mehr ...
