(Avtor) McElfresh, J. Steven (Avtor) Hanks, Lawrence M. (Avtor) Millar, Jocelyn G. (Avtor) sex pheromone(Z)-11-octadecen-1-yl accis-vaccenyl acetatewoodborerWe report the identification, synthesis, and field bioassays of a female-produced sex attractant pheromone component of the cerambycid beetle Ortholeptura valida (LeConte). Headspace volatiles from females contained a female-specific compound, (Z)-11-octadecen-1-yl acetate, which elicited a strong response from antennae of adult males in coupled gas chromatography-electroantennogram analyses. In field bioassays, significant numbers of males were collected by traps baited with this compound. The pheromone represents a new structural class of cerambycid pheromones, and is the first pheromone identified for a cerambycid species in the subfamily Lepturinae.20112024-08-05 09:54:25Neznano20047sl
