Vegetal synergists for trapping the adult of Scyphophorus acupunctatus Gyllenhal, in pheromone baited traps, in Agave angustifolia Haw., in Morelos, Mexico | Vegetal synergists for trapping the adult of Scyphophorus acupunctatus Gyllenhal, in pheromone baited traps, in Agave angustifolia Haw., in Morelos, Mexico

Английский. The agave weevil Scyphophorus acupunctatus Gyllenhal (Coleoptera: Dryophthoridae) is the main insect pest of wild and cultivated agaves in Mexico and in other countries. The management of this pest is complicated because to its cryptic habits. Recently, it has been developed a trapping system based with synthetic pheromone and food bait for monitoring this insect. However, an important part of the any trapping system is to know if any can synergize the response of the insect to the synthetic pheromone. In this study, we evaluated several vegetal tissue and ripped fruits for determining its potential as synergist for the synthetic pheromone for trapping the agave weevil in “agave espadín mezcal”, in Tlaltizapán, Morelos state. The vegetal evaluated were: “maguey espadín criollo” tissue, “maguey espadín oaxaqueño” tissue, “maguey papalote” tissue, sugarcane tissue, ripped pineapple fruit, ripped banana fruit, ripped guava fruit, ripped apple fruit, and tuberose flower. Our results showed that the best synergists were agave tissue, pineapple, banana submerged in soapy water.

Scyphophorus acupunctatus Gyllenhal (Coleoptera: Dryophthoridae) es el insecto plaga más importante de diversas especies de agave silvestre y cultivadas en México y otros países. El manejo de este insecto se dificulta debido a los hábitos bio-ecológicos del insecto. Recientemente, se ha desarrollado un sistema de trampeo basado en feromona sintética y cebo alimenticio para monitorear a este insecto. Sin embargo, es importante conocer algunos vegetales que pueden sinergizar la respuesta de este picudo a la feromona sintética. En este estudio, se evaluaron diversos vegetales en trampas colocadas en una plantación de agave espadín, en Tlaltizapán, Morelos. Los sinergistas vegetales evaluados fueron: tejido vegetal de maguey mezcalero espadín criollo (Agave angustifolia Haw.), espadín oaxaqueño (Agave angustifolia Haw.) y maguey mezcalero papalote (Agave cupreata Trel.), tejido de caña de azúcar, fruta madura de piña, plátano, guayaba y manzana, y flor de nardo. Se encontró que los mejores sinergistas fueron tejido de agaves, piña y plátano sumergidos en el agua jabonosa de la trampa.
