Abstract
Mass trapping is a widely employed technique for tephritid control in Uruguay, involving traps baited with food attractants aimed at capturing Ceratitis capitata and Anastrepha fraterculus adults. Previous studies have found high capture efficiency for sexually immature females, with minimal attractiveness to beneficial arthropods for most of the commercial attractants assessed in McPhail traps. This study aimed to assess tephritid capture effectiveness and selectivity towards beneficial arthropods when using these food lures with commercial traps. Five products were evaluated in 2019, including CeraTrap®, PlusTrap®, TMA ® and ANA lure® (both with insecticide DDVP, dry traps), and PBX yeast® (McPhail trap). The primary finding was that commercial trap design did not significantly enhance attractant performance in terms of efficiency or selectivity for the commercial products evaluated. However, these products demonstrated efficacy in capturing immature C. capitata females while showing selectivity towards beneficial entomofauna. Further research is needed to develop effective food attractants for controlling A. fraterculus under Uruguayan fruit production conditions.
