Abstract:A wind-oriented trap (WORT) for evaluating two or more different blends of sex pheromone simultaneously was designed and field-tested against fall army worm, Spodoptera frugiperda (J. E. Smith), and velvet bean caterpillar (VBC), Anticarsia gemmatalis Hübner. Moth captures showed that these speciescan detect differences in pheromone blends positioned as close as 1m apart. Up to four different blends of VBC pheromone were evaluated on the same WORT, and responding males demonstrated a preference for a specific blend compared with other blends of the same pheromonal components. WORTs baited with rubber septa containing either 0.2 or 0.5 mg pheromone per septum caught about the same number of VBC males. However, a 20-fold increase in pheromone per septum (10 mg dose) resulted in reduced catches compared with an adjacent bucket trap on the same WORT (buckets 1m apart) baited with 0.5 mg pheromone per septum. The WORT is an excellent tool for evaluating pheromone blends and pheromone release rates for optimum trap captures.
