We report the identification, synthesis, and first field bioassays of a pheromone component with a novel structure produced by adult males of Chlorida festiva (L.) and Chlorida costata Audinet-Serville, longhorn beetle species in the subfamily Cerambycinae. Headspace volatiles from males contained a sex-specific compound that was identified as (6E,8Z)-6,8-pentadecadienal. Traps baited with this compound captured adults of both species and sexes, consistent with the aggregation-sex pheromones produced by males of many species in this subfamily. This compound represents a new structural class of cerambycid pheromones, and it is the first pheromone identified from species in the tribe Bothriospilini.
