Three commercially available sex pheromone lures (Trécé, Scentry, and Hercon) for the beet armyworm, Spodoptera exigua (Hübner), were effective for capturing males in Universal Moth Traps (Unitraps). The Trécé and Scentry lures were equally effective, and there was some evidence for significantly greater captures with Hercon than with Trécé lures. Longevity of the Trécé. Scentry, and Hercon lures was 23, 37, and 28-37 d, respectively. Of the trap designs evaluated, Unitraps were the most effective. All-green and all-white Unitraps baited with Trécé lures were significantly less effective than those with a green cover, yellow top, and white bottom (multicolored). Multicolored Unitraps captured significantly greater numbers of males than Multipher 1, 2, or 3 traps, and than commercially fabricated wire cone or commercially available Scentry Heliothis traps. Checking the Scentry Heliothis traps daily, rather than at 2- or 3-d intervals, as a way to reduce escape of moths that did not enter the trap tops, did not increase efficacy relative to Unitraps. There was no significant difference between captures in the wire cone and Scentry traps. These data should be useful in developing a standard trapping system for monitoring and population dynamics studies of the beet armyworm.
