[Objectives]  To determine the efficacy, duration and most cost-effective dosage of sex pheromones for controlling Adoxophyes orana beijingensis Zhou et Fu in different orchards. [Methods]  Sex pheromone dispensers containing 0.3 g pheremone/unit were hung on apple and peach trees at a density of 600, 500 and 400 per hectare to disrupt the mating of A. orana in Zhengzhou from 2013 to 2014. [Results]  The control efficacies of 600, 500 and 400 per hectare in peach orchards over 124 days were 85.86%, 91.98% and 70.12%, respectively before overwintering adult emergence, but declined rapidly after August. However, control efficacies of all three densities were 100% in apple orchards over a 5 month period. [Conclusion]  A pheromone unit density of 400 per hectare appearssufficient to control A.orana in mid-early ripening peach orchards but a density of 500 per hectare or higher was required in late-mature orchards. The duration of control was 4 months. A density of 400 units per hacouldbe enough to keep Adoxophyesorana at low density in apple orchards for 4 months.
