Mass trapping is being developed to control the fruit fly Anastrepha ludens (Loew) (Diptera: Tephritidae) in some citrus-growing areas of Mexico using a trap-lure pack composed of CeraTrap® lure and a specific bait station (MS2®). The technique is based on placing a sufficient density of baited traps so that enough flies are captured to account for an important reduction in fruit infestation in the orchard. Trap-lure efficacy, trap density and cost ratio are crucial for broad implementation of this technique by growers. The use of handmade traps, constructed from 500 mL plastic bottles, with 3 10 mm holes at ⅔ up from the base, had similar attraction but captured more flies under caged conditions than 2 commercial traps sold in Mexico for this purpose. Under field conditions, the capture of A. ludens with plastic bottle traps was statistically superior to that of MS2® traps. When placed at a density of 40 traps per ha in an orange (Citrus sinensis [L.]; Rutaceae) orchard, bottle traps had a significantly higher capture rate than a similar density of MS2 traps and provided satisfactory crop protection, with 0.3- 2.3% of fallen fruits infested at harvest. The low cost of this trap, (∼US$ 0.18), has the potential to greatly reduce mass trapping costs and could favor broad implementation of this strategy in Latin American countries that produce fruit crops affected by A. ludens.
