Wood-boring beetles of the Cerambycidae are important pests of trees in forests, plantations, and urban landscapes world wide, but have long been difficult to control because of the lack of information on their pheromones. We recently have identified long-range pheromones of ten cerambycid species, more than doubling the number of species in this family for which pheromones have been identified over the last 20 years. Moreover, we have determined that pheromones of the species studied to date conform to a certain structural motif. This finding will greatly facilitate identification of pheromones of other species in the future. New information on pheromones will provide tools for sampling and managing a number of cerambycid pests, including exotic species that are entering North America at an ever increasing rate.
