Popis: Development of cost-effective traps and attractants is important for sustainable pest management. In the case of the Medfly, Ceratitis capitata Wiedemann, a worldwide pest of fruit production, recent interest in development of mass trapping strategies and low-cost easy-to-get artisanal traps for resource poor grower use has prompted renewed interest in research on attractants and traps. Additionally, such interest is also rooted on the need for effective female attractants to monitor wild population dynamics under male-only sterile fly releases. Response of wild flies and sterile males to makeshift traps (modified polyethylene terephthalate (pet) bottles) baited with fruit juice and wine vinegar dilutions with and without the addition of sugar revealed that a 50% dilution of wine vinegar or sweetened orange juice were more attractive than the standard Torula baits during the offseason (after harvest) in a peach orchard in arid irrigated valleys of San Juan Argentina. Such results suggest that volatiles from orange peel and juice are good candidates for development of Medfly attractants, and that pet bottles baited with sweetened orange juice and wine vinegar may be used by small growers and homeowners as low-cost-effective traps for Medfly control. Our results also suggest that Medfly response to food-based and fruit-based volatiles may be seasonally dynamic, a finding with important pest management implications.
