The use of simple and economic traps with long lasting lure dispensers is key for implementation of mass trapping strategies against pestiferous fruit flies. Simplicity, cost, ease of assembly, storage and transportation were considered during evaluation of a folding conical trap for mass trapping the Mexican fruit fly, Anastrepha ludens. The application of deltamethrin to the lid of the trap resulted in a cost-effective treatment, which helped retain flies in dry traps for at least 10 wk. However, the conical trap design and the diam, type and disposition of entry-holes, negatively affected performance of the trap under laboratory conditions. High numbers of flies could escape the trap over a short period of time after their release into its interior, although most of them died after escaping because of the delayed effect of exposure to deltamethrin. Under field conditions, no significant differences were observed between orange and yellow traps in capturing either A. ludens or lacewings. In contrast, the folding conical trap model was significantly more efficient in capturing Mexican fruit flies when baited with CeraTrap® lure than when baited either with the conventional hydrolyzed protein or with BioLure®. CeraTrap® lure was also significantly more attractive to beneficial lacewings than the other 2 lures. These results indicated that additional studies on fly population suppression under field conditions will be necessary before deciding to use the folding conical trap as part of a mass trapping strategy to control the Mexican fruit fly.
