Abstract

We examined captures of wild Mediterranean fruit flies, Ceratitis capitata (Wiedemann), and oriental fruit flies, Bactrocera dorsalis (Hendel), in Jackson and McPhail traps baited with juice from ripe coffee fruits. Both males and females of each species were captured. Jackson traps baited with coffee juice caught significantly more C. capitata females than did traps baited with water or trimedlure. Fewer B. dorsalis males and females were captured in traps baited with coffee juice compared with other traps. McPhail traps baited with coffee juice caught more C. capitata female and male flies than those baited with water, and they were equal to those baited with Nu-Lure or a water + sugar mixture. McPhail traps baited with coffee juice caught more B. dorsalis female and male flies than those baited with water or Nu-Lure, and they were equal to those baited with a water + sugar mixture. Findings are discussed with respect to the physiological condition of responding C. capitata females and development of a female attractant.
