Factors affecting the trapping of males of Spodoptera frugiperda (Lepidoptera: Noctuidae) with pheromones in Mexico
Florida Entomologist 87 (3), 288-293
Abstract: Four commercial sex pheromones and virgin females were tested as attractants for male fall armyworm (FAW), Spodoptera frugiperda with Scentry Heliothis traps in sorghum fields in Chiapas, Mexico. We observed significant differences among the lures tested. Pherotech, virgin females, and Scentry lures elicited different responses from Chemtica and Trece lures. In another experiment performed in Michoacán, Mexico, we found that Scentry Heliothis traps baited with Chemtica lures placed at 1.5 m above ground caught significantly more males than traps placed at a height of 2 m. In contrast, the capture of S. frugiperda males with bucket traps placed at 1 m height was not significantly different from that of traps placed at 1.5 and 2 m height. When baited with pheromone, Scentry Heliothis traps caught more non-target insects than bucket traps. Apidae was the most prevalent family of non-target insects caught in both experiments.

Se evaluaron cuatro feromonas comerciales y hembras vírgenes como atrayentes contra el gusano cogollero Spodoptera frugiperda usando trampas tipo Heliothis en un campo de sorgo en Chiapas. Las capturas de los machos con las feromonas comerciales Chemtica y Trece fueron significativamente diferentes a las capturas obtenidas con las feromonas Pherotech, Scentry y hembras vírgenes. En otro ensayo realizado en el Estado de Michoacán, México, encontramos que las capturas obtenidas con las trampas tipo Heliothis cebadas con feromona de Chemtica y colocadas a una altura de 1.5 m arriba del suelo, fueron significativamente mejores que las capturas de las trampas colocadas a 2 m. Por lo contrario, las capturas obtenidas con las trampas bucket colocadas a 1 m de altura fueron muy similares a las de las trampas colocadas a 1.5 m y 2 m. Las capturas de la entomofauna asociada fueron mucho mayores en las trampas tipo Heliothis que las obtenidas con las trampas bucket, siendo Apidae la familia más abundante.
