Abstract Female orange tortrix,Argyrotaenia citrana (Fernald), abdominal tip extracts, and effluvia were analyzed, and two pheromone components were identified ascis-11-tetradecenal (c11–14∶ALD) andcis-11-tetradecenyl acetate (c11–14∶Ac). Female extracts contained such very low quantities of c11–14∶ALD relative to c11–14/∶Ac that the aldehyde was frequently undetectable, whereas female effluvia contained these compounds in a ratio of ca. 15∶1. Field attractancy tests showed that traps baited with c11–14∶ALD were attractive, whereas c11–14∶Ac possessed no intrinsic attractiveness. Additionally, traps containing c11–14∶ALD in a range of ratios to the component c11–14∶ Ac (5∶1 to 1∶10) are more competitive forA. citrana males than are live female traps. The females produce purecis isomers (〈0.5%trans), and addition of 〉5% t11–14∶ALD (the geometric isomer of the primary component) reduces attractancy, whereas addition of t11–14∶Ac (the geometric isomer of the secondary component) apparently does not affect attractancy significantly unless c11–14∶Ac is absent.
