Abstract

El objetivo del trabajo fue evaluar la técnica de control de Tecia solanivora (Lepidoptera: Gelechiidae) por
medio de la interrupción del apareamiento para su posible factibilidad en el cultivo de la papa. En un túnel de viento una mezcla antagónica de la feromona constituida por E3-12Ac, Z3-12Ac y 12Ac en la proporción 100:50:100, respectivamente (70 mg por dispensador) produjo una inhibición total en la atracción de machos hacia la feromona liberada por las hembras, en comparación con hembras liberando la feromona (69% de atracción). En campo esta mezcla a 10 hg/trampa inhibió significativamente la captura con dos machos/trampa, a diferencia de trampas control conteniendo E3-12Ac y Z3-12Ac (100:1 respectivamente) capturándose 50 machos/trampa. En 3 ha tratadas con la mezcla antagónica en dispensadores colocados en la base de plantas de papa a una densidad de 1.227 dispensadores/ha, (equivalente a 86 g de feromona/ha), se redujo significativamente la captura de machos en trampas para monitoreo en 94%, en 89% en trampas
con hembras y la cópula de parejas confinadas se redujo en 67%, en comparación con un área testigo (1 ha sin tratar).
Estos resultados indican el potencial de esta técnica para reducir poblaciones de la plaga.

The aim of this study was to evaluate the control of Tecia solanivora (Lepidoptera: Gelechiidae) through mating disruption for its possible feasibility in potato crops. In a wind tunnel, an unbalanced blend of the pheromone consisting of E3-12Ac, Z3-12Ac and 12Ac in the proportion 100:50: 100, respectively (70 mg per dispenser), produced a total inhibition of male attraction to the pheromone released by females, as compared to females releasing the pheromone (69% attraction). In the field, this blend at 10 eta g/trap significantly inhibited capture with two males/trap, whereas control traps containing E3-12Ac y Z3-12Ac (100: 1 respectively) captured 50 males/trap. In 3 ha treated with the unbalanced blend in dispensers placed at the base of potato plants at a density of 1,227 dispensers/ha (equivalent to 86 g of pheromone/ha), male attraction was significantly reduced to monitoring traps by 94%, by 89% to traps with females, and mating of confined pairs was reduced by 67%, in comparison with a control area (1 ha untreated). These results indicate the potential of this technique for reducing populations of the pest.
