Extracts of terminal abdominal segments of female Lacanobia subjuncta contained (Z)-11-hexadecenyl acetate, (Z)-11-hexadecenal, and (Z)-11-hexadecenol at a ratio of 1:0.2: 0.02. (Z)-11-hexadecenyl acetate and (Z)-11-hexadecenal were most effective as a lure for trapping males when loaded in rubber septa at ratios near 3:1, respectively. The complete three-component blend was most effective as a lure for trapping males when loaded in rubber septa at a ratio of 3:1:0.08 for the acetate, aldehyde, and alcohol, respectively. In a comparison of doses of this three-component blend, greatest numbers of males were captured with 6.1 mg per rubber septum. These components, when loaded with an optimum ratio of components and suitable dose, should provide a useful lure for trapping Lacanobia subjuncta in agroecosystems, permitting monitoring of distribution, emergence, and flight periods
