Sex pheromone of the flax budworm, Heliothis maritima adaucta Butler (Lepidoptera: Noctuidae)
Applied Entomology and Zoology 38 (1), 73-78
Abstract: Sex pheromone of the flax budworm, Heliothis maritima adaucta, was extracted from abdominal tips of virgin females using hexane. Three EAD-active peaks were detected in the extract by the GC-EAD method. These peaks were identified to be (Z)-11-hexadecenal (Z11-16:Ald), (Z)-11-hexadecen-1-ol (Z11-16:OH), and n-hexadecenal (n-16:Ald) by GC-MS analysis. The ratio of Z11-16:Ald, Z11-16:OH, and n-16:Ald was 100:24.5:2.4, and the amount of Z11-16:Ald was about 18.1 ng per female. Mixtures of Z11 -16:Ald and Z11-16:OH in ratios of 100: 1-6 attracted males in the field, but the each compound alone did not. White rubber septa impregnated with 1.01 mg and 3.03 mg of a mixture of Z11-16:Ald and Z11-16:OH in a ratio of 100: 1 could capture more males than those with smaller doses. Addition of n-16:Ald to binary mixtures did not increase their attraction activity. Therefore, Z11-16:Ald and Z11-16:OH were concluded to be essential components of the sex pheromone of H. m. adaucta for male attraction. Also, addition of (Z)-9-hexadecenal, a pheromone component in a subspecies in Hungary, to the above binary mixture did not increase the attraction activity.
