Field trappings were conducted in using a three-component synthetic sex pheromone consisting of (Z)-11-tetradecenyl acetate (Z11-14Ac), (Z)-9-dodecenyl acetate (Z9-12Ac), and 11-dodecenyl acetate (11-12Ac) to develop a potent attractant lure for males of the oriental tea tortrix moth, Homona magnanima DIAKONOFF. Persistency of attractiveness on three kinds of dispensers such as chopped cotton rope, plastic capsule, and rubber septum was 2 days, 2 weeks, and 1 month, respectively. Addition of E-isomers of the pheromone components at a dose of less than 10% did not affect the attractiveness. Optimum ratio of the two minor components, Z9-12Ac and 11-12Ac, coincided with their natural ratio, 3 to 1. But the optimum ratio of the major component, Z11-14Ac, was twice that of the natural ratio. Based on these results, a 60 : 3 : 1 blend of Z11-14Ac, Z9-12Ac, and 11-12Ac loaded on a rubber septum (3.2 mg in total) was recommended as an attractant lure for males of the oriental tea tortrix moth.
