Within the family Cerambycidae (Coleoptera), (E)-6,10-dimethyl-5,9-undecadien-2-ol (fuscumol) and (E)-6,10-dimethyl-5,9-undecadien-2-yl acetate (fuscumol acetate) have been shown to attract several species in the subfamily Lamiinae. However, it is not yet clear whether beetles within the subfamily actually produce these compounds as pheromones or rather respond to them as kairomones. We report here that male Astyleiopus variegatus (Haldeman) produce both fuscumol and fuscumol acetate, suggesting that the compounds are indeed pheromones for this species. We also determined that the absolute configurations of these compounds are (S)-fuscumol and (S)-fuscumol acetate by synthesis of both enantiomers of each.
