The compounds were identified in extracts of female pheromone glands by coupled gas chromatographic - electroantennographic detection (GC-EAD) and coupled GC - mass spectrometry. In field experiments, traps baited with E9-12:OAc or Z9-12:OAc singly were unattractive to male CBT, but in combination at ratios of 50:50 or 40:60 captured numerous males. Increasing quantities of this two-component pheromone blend resulted in increasing captures of male CBT. This binary blend at a 10-mg dose caught more CBT males that did caged virgin CBT females. Eight other EAD-active acetates identified in extracts of pheromone glands failed to enhance attractiveness of the pheromone blend. These compounds may serve to reduce cross-attraction of heterospecific male moths or may play a role in courtship behaviour. Formulations of synthetic pheromone are being evaluated for management of the CBT using mass trapping or disorientation of male CBT moths.
