Mating disruption of beet armyworm (Lepidoptera: Noctuidae) in vegetables by a synthetic pheromone Academic Article uri icon


  • The pheromone dispenser, Yotoh-con-S, was evaluated for its ability to inhibit mate location and subsequent infestation by beet armyworm, Spodoptera exigua (Hubner) in head lettuce and broccoli. Pheromone dispensers consistently prevented male beet armyworm moths from locating synthetic lures or virgin females in treated fields. However, the dispensers were inconsistent in reducing the number of beet armyworm larvae, appearing to be most effective when population densities were low but ineffective when populations were high. Where beet armyworm larval populations were significantly reduced by the presence of synthetic pheromone dispensers, the resultant populations were usually not reduced to the point where insecticide applications could be eliminated.
