A pheromone lure for catching fall armyworm males (Lepidoptera: Noctuidae) in Mexico

Moth sex pheromones can be used for monitoring or for control (e.g., mass trapping or mating disruption) of agricultural pests. However, pheromone application in field conditions requires that all crucial pheromonal components are included and optimized in a pheromone lure. In this study, we optimiz...

description Moth sex pheromones can be used for monitoring or for control (e.g., mass trapping or mating disruption) of agricultural pests. However, pheromone application in field conditions requires that all crucial pheromonal components are included and optimized in a pheromone lure. In this study, we optimized a sex pheromone lure for monitoring Mexican populations from the fall armyworm (FAW), Spodoptera frugiperda Smith. In corn fields, we evaluated the activity of single compounds, three binary blends, and one tertiary blend of (Z)-7-dodecenyl acetate (Z7-12:OAc), (Z)-9-tetradecenyl acetate (Z9-14:OAc), and (Z)-11-hexadecenyl acetate (Z11-16:OAc). The results showed that the traps baited with a binary blend of Z7-12:Ac + Z9-14:Ac captured significantly more S. frugiperda males than single compounds, other binary blends or the tertiary blend. The absence of Z11-16:OAc in the blends did not significantly affect the capture of males, indicating that this compound is non-essential for male attraction in the field. We demonstrated that the dose of the binary blend of Z7-12:OAc and Z9-14:OAc influenced the catch rate of FAW males. The pheromone lure optimized in this study can be useful for capturing S. frugiperda in Mexico.

Las feromonas sexuales de palomillas se pueden usar para monitoreo o control de plagas agrícolas (por ejemplo, trampeo masivo o interrupción del apareamiento). Sin embargo, la aplicación de feromonas en condiciones de campo requiere que los componentes feromonales activos estén incluidos y optimizados como un cebo feromonal. En este estudio, preparamos un señuelo con la feromona sexual para monitorear las poblaciones mexicanas del gusano cogollero, Spodoptera frugiperda (J. E. Smith). Evaluamos la actividad de compuestos individuales, tres mezclas binarias y una mezcla terciaria de (Z)-7-dodecenil acetato (Z7-12: OAc), (Z)-9-tetradecenil acetato (Z9-14: OAc) y acetato de (Z)-11-hexadecenilo (Z11-16: OAc), en cultivos de maíz. Los resultados mostraron que las trampas cebadas con una mezcla binaria de Z7-12: Ac + Z9-14: Ac capturaron significativamente más machos de S. frugiperda que los compuestos individuales, y que las otras mezclas binarias o la mezcla terciaria. La ausencia de Z11-16: OAc en la mezcla no afectó significativamente la captura de machos, lo que indica que este compuesto no es esencial para la atracción de machos en el campo. Encontramos que la dosis de la mezcla binaria de Z7-12:OAc y Z9-14:OAc influyó en la tasa de captura de machos del gusano cogollero. El señuelo de feromona optimizado en este estudio puede ser útil para capturar S. frugiperda en México.
