Dispensers released either a blend of (E)-9-dodecenyl acetate (E9-12:OAc, 49.5%), (Z)-9-dodecenyl acetate (Z9-12:OAc, 49.5%), and (Z)-7-decenyl acetate (Z7-10:OAc, 1%) at a rate of 29 mg/day (Exp. 1), or E9-12:OAc alone at 27 mg/day (Exp. 2), 4 mg/day (Exp. 3), or 0.5 mg/day (Exp. 4). A sticky Delta trap baited with a grey rubber septum impregnated with CBT pheromone components E9-12:OAc (40 μg), Z9-12:AOc (60 μg), and Z7-10:OAc (1 μg) was placed in each tree. Captures of male CBTs in treatment trees were significantly reduced compared with control trees in all experiments. Results suggest that disruption of pheromone-based communication in CBT around individual cherry trees is feasible with a pheromone blend or with E9-12:OAc alone, and could become part of an integrated management strategy for CBT in urban environments.
