Mixing male lures results in an effective multispecies bait for trapping Bactrocera (Diptera: Tephritidae) fruit flies

Detection of Bactrocera Macquart (Diptera: Tephritidae) fruit flies relies on male-specific lures, methyl eugenol and cue lure, which are presented singly in traps. We compared the efficacy of the standard single-lure treatments against mixtures of methyl eugenol and raspberry ketone (a natural analogue of cue lure) deployed in the same trap. No significant differences were found in captures of Bactrocera cucurbitae (Coquillett) or B. dorsalis (Hendel) male flies over 8 wk intervals between traps baited with a single lure and traps baited with any of the 3 mixtures tested.
Sumario
La detection de moscas de la fruta Bactrocera (Diptera: Tephritidae) depende de los señuelos específicos para los machos, metil eugenol y el señuelo de referencia, que se presenta indivualmente en las trampas. Se comparó la eficacia de los tratamientos estándar de un solo señuelo contra mezclas de metil eugenol y la cetona de frambuesa (un análogo natural del señuelo señuelo de referencia) puesto en la misma trampa. No se encontraron diferencias significativas en las capturas de machos de Bactrocera cucurbitae (Coquillett) o B. dorsalis (Hendel) por los intervalos de 8 semanas entre las trampas cebadas con un único señuelo y trampas cebadas con cualquiera de las 3 mezclas probadas.
