Sex pheromone components of female smaller tea tortrix moth,Adoxophyes sp. (Lepidoptera: Tortricidae) in Taiwan.

(Z)-11-Teiradecenyl acetate (Z11-14: Ac) and (Z)-9-tetrade-cenyl acetate (Z9-14: Ac) were isolated as major sex pheromone components from the female tips of the smaller tea tortrix moth,Adoxophyes sp., in Taiwan. The average amount ofZ11- andZ9-14: Ac in each female gland was 24.9 and 14.1 ng, in a ratio of 64∶36, respectively. When compared to a closely related Japanese strain, which used theZ9-14: Ac,Z11-14∶ Ac,E11-14:Ac, 10-Me-12:Ac four-component system (in a ratio of 63∶31∶4∶2), the Taiwan formulation of two components caught significantly more Taiwan males than the Japanese formulation of four components.
