Comparative Volatilization of Three Lures for Male Tephritids in Hawaii: Methyl Eugenol (Oriental Fruit Fly), Cue-Lure (Melon Fly), and Trimedlure (Mediterranean Fruit Fly)

Abstract Volatilization of cue-lure, methyl eugenol, and trimedlure, the synthetic lures for male melon flies, Dacus cucurbitae Coquillett, oriental fruit flies, D. dorsalis Hendel, and Mediterranean fruit flies, Ceratitis capitata (Wiedemann), respectively, was found to take place at different rates: cue-lure showed a low level of volatility; trimedlure is comparatively very volatile; methyl eugenol is intermediate but was more similar to cue-lure than to trimedlure. Traps baited with even trimedlure would need only infrequent servicing if a lure reservoir were incorporated with the wick, and if the reservoir were made large enough to contain adequate supplies of trimedlure.
