In the recent past, several studies have evaluated the attractiveness of colored multilure traps/lure combinations to capture the Mexican fruit fly, Anastrepha ludens (Loew) (Diptera: Tephritidae). When promising traps and lures from those trials where used in a current program for monitoring A. ludens in the citrus orchards of northeast Mexico, the results were very variable. Thus, we reconsidered the issue and evaluated in citrus trees green and yellow multilure traps plus a clear multilure trap more alike to the McPhail trap; the included lures were: torula yeast, ammonium acetate, borax, putrescine, an antifreeze [based in propylene glycol], commercial grape juice, liquefied raisins, and an artificial grape-flavor drink. The combinations were compared against the traditional McPhail trap+torula yeast. During the 2004 winter in northeast Mexico, clear multilure traps with torula yeast attracted >4 times irradiated Mexican fruit flies than McPhail traps (P>0.02); however, these differences were no significant during the 2005 spring. In comparison with ammonium acetate+putrescine+antifreeze, liquefied raisins, the artificial grape-flavor drink, and torula yeast in the McPhail trap, the treatment with commercial grape juice had the highest capture of Mexican fruit flies (P>0.001). Our results have implications for the monitoring of the pest in Mexico.
