Interpretive Summary: Field experiments aimed to compare different trapping systems for the olive fruit fly, Bactrocera oleae (Rossi) were conducted in Chios Greece from 2001 to 2003. Among the various treatments tested, plastic McPhail type traps baited with an aqueous solution of the protein NuLure (9%) plus borax (3%) was the most effective trap for the olive fruit fly, followed by the same traps provided with water in their base and baited with an one-month-lasting ammonium bicarbonate (AB) dispenser. However, NuLure-baited traps were the least selective capturing large number of non-target insects. Interestingly though, they capture less Chrysopids (beneficial insects) than AB baited traps. Addition of a dispenser of the sex pheromone Spiroketol (SK) in AB-baited traps or on sticky-coated green panels did not increase captures of males neither the total number of adult B. oleae captured. AB-baited traps provided with water in their bases were more effective than similarly baited dry traps provided with DDVP as a killing agent. NuLure-baited plastic McPhail traps were also more effective than same traps baited with AB and one dispenser of either ammonium acetate, or putrescine or trimethylamine. They were also more effective than traps baited with AB and the above three attractants. Interestingly though the addition of a putrescine dispenser to AB baited traps increase their performance. The importance of our findings for the monitoring and control of the olive fruit fly is discussed.
