Abstract (R)-Solanone was identified as a female-specific compound from aerations of virgin females of the scale insect, Aulacaspis murrayae Takahashi. The stereochemistry of the insect-produced solanone was confirmed to be (R) by comparison with synthesized racemic and chiral standards on a chiral stationary phase GC column. In bioassays, males were strongly attracted to a synthesized sample of (R)-solanone, demonstrating that this compound is a sex pheromone component for this species. Keywords (R)-Solanone . Tobacco . Aulacaspis murrayae . Diaspididae
pheromones for scales, and related mealybug species, have been identified. Applications for some of these pheromones as pest management tools have been developed, for example, for the agricultural pests yellow scale, Aonidiella citrina Coquillet (Grafton-Cardwell et al. 2000) and red scale, Aonidiella aurantii Maskell (Grout and Richards 1991; Vacas et al. 2009, 2010). With these precedents, it seemed likely that females of the sexually reproducing A. murrayae would also have a sex pheromone. Thus, the objective of this project was to identify possible sex pheromone components of this species, with the eventual goal of being able to use the pheromone for sampling and possibly control of this pest. Here, we report the identification, synthesis, and testing of a female-produced sex pheromone for this species.
Introduction The scale insect, Aulacaspis murrayae Takahashi (Hemiptera: Diaspididae), is a serious pest of the ornamental plant orange jasmine, Murraya paniculata (Linn.), which is widely used for hedges in Taiwan. Scale damage includes yellowing, desiccation, and finally death of the plant. Females of many sexually reproducing scale insect species are known to produce powerful sex pheromones for attracting the fragile and ephemeral males for mating. A number of H.
