Abstract : Thirteen trap-attractant combinations were evaluated for effectiveness in catching females of C. capitata and other species of fruit flies. The experiments were carried out in agrosystems of coffee, citrus and mango orchards located in a sterile insect release area in the Soconusco region of Chiapas, Mexico, during the period 1995-98. The evaluation was focused to compare food attractants (i.e., putrescine, ammonium acetate and trimethylamine) with standard attractants such as trimedlure and liquid hydrolysed protein. For the trapping system, dry traps (Jackson trap, OBDT (Open Bottom Dry Trap), etc.) as well as wet traps (McPhail trap, Tephri trap etc.), were tested alternately with different kind of attractants. The results consistently showed that the combination of ammonium acetate+putrescine+trimethylamine was the best for the capture of females of C. capitata when used in traps such as the OBDT and plastic McPhail trap (IPMT). For Anastrepha spp., the McPhail trap baited with liquid hydrolysed protein still seems to be the best option, although the combination of ammonium acetate plus putrescine was quite consistent capturing A. obliqua and A. ludens in traps such as the IPMT. This could offer the advantage of using a dry trap for monitoring this fruit fly species.
