Identification of the sex pheromone of Cydia splendana (Lepidoptera, Tortricidae) bypheromone gland analysis followed by field trapping with synthetic compounds showsthe occurrence of two pheromone races. Acorn moth females from Sweden, whereoak Quercus robur is the only host plant, use a blend of the E,Z and E,E isomers of8,10-dodecadien-1-yl acetate. In Central and Southern Europe, where C. splendana feedson chestnut Castanea sativa and several species of oak, males respond to another isomerblend, E,E and Z,E. The distribution of the two pheromone races of C. splendana overlapsin Northern France, where they share oak as plant host. Differences in sex communicationsignals between these populations of C. splendana corroborate the role of specific materecognition in speciation events.
