Capture of Mediterranean fruit flies (Diptera: Tephritidae) using color inserts in trimedlure-baited Jackson traps
Environmental Entomology 25 (2), 256-260
Abstract: Tests of the capture of wild Mediterranean fruit flies, Ceratitis capitata (Wiedemann), were made using a commercially produced adhesive paper available in several different colors as an insert in trimedlure-baited Jackson traps. Colors tested included fluorescent orange, fluorescent yellow, fluorescent light green, dark green, black, and white. These inserts were compared with the standard white inserts, which use sticky material that is manually applied. Tests were conducted in both citrus groves and coffee fields in Guatemala, and in a coffee field in Hawaii. Generally, inserts made with the fluorescent colors captured more flies than those with nonfluorescent colors. Traps with light green inserts captured a higher percentage of total flies than did traps with the standard white inserts in 3 of the 4 trials. Traps containing either yellow or orange inserts captured significantly more flies than the standard white insert in 2 of the 4 trials. Traps containing black inserts tended to catch a relatively low percentage of flies. There were differences in host species, host fruit availability, and fruit fly population levels among the various trials. These factors may influence the role of color cues in the capture of male flies by trimedlure-baited traps.
