title: Sex pheromone specificity: taxonomic and evolutionary aspects in lepidoptera.
abstract: Sex pheromone specificity is the only obvious reproduction isolating mechanism for two tortricid species and two gelechiid species. Pheromones of the gelechiid species are cis-9-tetradecenyl acetate and trans-9-tetradecenyl acetate. Male response of one gelechiid species is inhibited by the pheromone of the other species. This could be important for sympatric evolutionary saltation.
