Capture of Diaprepes abbreviatus (Coleoptera: Curculionidae) in Frass Extract-Baited Traps in Citrus

In field trapping studies in central Florida during the fall of 1981 and the spring, summer, and fall of 1982, more Diaprepes abhreviatus (L.) were captured with frass or frass extracts than with other treatments. Extracts of frass from male weevils in traps captured more males or females than extracts of frass from female weevils. Extracts of frass in methanol captured more weevils at high than at low concentration.
