| description | The agave weevil, Scyphophorus acupunctatus Gyllenhal, is considered the most important insect pest of the cultivated agaves in Mexico. Recent studies on the chemical ecology of this weevil have shown that males release a pheromone that attracts both sexes; the pheromone is composed of four components. Previous field experiments showed that all components, singled or in blends, were attractive to the weevils, but compounds 2-methyl-4-heptanone (C1) and 2-methyl-4-octanone (C2) were sufficient to obtain captures equivalent to those by the quaternary blend. In this study, we investigated the effect of different ratios (1:1, 1:2, 1:4, 2:1, and 4:1) and doses (50, 100, 150, 200, 350, and 500 mg)of C1 and C2 in the captures of the agave weevils in commercial plantations of Agave tequilana Weber. Our results showed that traps baited with synthetic pheromone captured more weevils than traps baited with adult male weevils but the different ratios of C1 and C2 did not affect the weevils capture. In fact, traps baited with C2 caught more weevils than those baited with the binary blend. Also, we found that weevil’s capture was not affected by dose. In general, traps baited with the synthetic pheromonal components caught more females than males. |

El picudo del agave, Scyphophorus acupunctatus Gyllenhal, es una plaga de importancia económica en diferentes cultivos de agaves en México, principalmente en agave tequilero, agave mezcalero y henequén. Los machos de esta especie liberan una feromona de agregación que atrae a ambos sexos, la feromona esta compuesta por dos alcoholes y dos cetonas. Experimentos previos han mostradoque los cuatro compuestos son atractivos a los picudos del agave, pero las mayores capturas se obtuvieron cuando se combinaron la 2-metil-4-heptanona (C1) y la 2-metil-4-octanona (C2). En el presente estudio se realizaron experimentos en campo para evaluar el efecto de las proporciones (1:1, 1:2, 1:4, 2:1 y 4:1) y la dosis (50, 100, 150, 200, 350, y 500 mg) de C1 y C2 en la captura de los picudos. Los resultados muestran que las diferentes proporciones probadas de los dos componentes feromonales no afectaron las capturas de los insectos. De hecho las trampas cebadas con C2 tuvieron mayores capturas que trampas cebadas con la combinación de los dos compuestos. Con respecto al otro factor evaluado,nuestros resultados muestran que la dosis no afectó las capturas de trampas cebadas con la feromona. Las trampas cebadas con los compuestos feromonales sintéticos capturaron más hembras que machos.
