The sex pheromones of Spilonota ocellana D. & S. and Spilonota laricana Hein. (Lepidoptera:Tortricidae) were identified by chemical analysis and field trapping. Female moths of the two species produce (Z)‐8‐tetradecenyl acetate, (Z)‐8‐tetradecen‐1‐ol and dodecyl acetate in almost the same proportions (98:1:1 and 97:3:1). Males of both species were best attracted to a blend of 10:1 to 1:1 Z8‐14Ac:Z8‐14OH. This indicates that mating barriers other than sex pheromones exist between sympatric populations.
