Abstract:		"Sex pheromones are used by insects as a form of chemical communication for the purpose of attracting conspecific mates. Female moths Cadra cautella and Spodoptera exigua use the diene (Z,E)-9,12-tetradecadienyl acetate as the major pheromone component. Biosynthesis of this pheromone component was demonstrated to occur through delta 11 desaturation of hexadecanoic acid (palmitate) to produce (Z)-11-hexadecenoic acid which is then chain-shortened to (Z)-9-tetradecenoic acid. A unique delta 12 desaturase uses the (Z)-9-tetradecenoic acid to produce (Z,E)-9,12-tetradecenoic acid which is reduced and acetylated to form the acetate ester pheromone component. Both moths also use a pheromonotropic peptide to stimulate pheromone biosynthesis"
