A newly identified chemical sex attractant, or pheromone, of the emerald ash borer could mean improved traps for monitoring and controlling the tree-killing beetle. That's the goal of U.S. Department of Agriculture (USDA) entomologist Allard Cossé and his colleagues.
More recently, the team discovered a macrocyclic lactone (3z-dodecan-12-olide -see structure), a compound that female borers release while feeding. Large-scale field tests conducted in Canada and the United States showed that the compound attracts male borers and has potential for use in traps either alone or combined with ash-tree-based attractants, reports Cossé, at the ARS National Center for Agricultural Utilization Research in Peoria, Ill........
