(7Z,11Z,13E)-hexadeca-7,11,13-trienal is a sex pheromone component isolated from the codling moth (Cydia pomonella), used for monitoring and controlling this pest. It specifically attracts male codling moths and can be used as a highly effective lure for monitoring pest population dynamics and as part of an integrated pest management (IPM) strategy. By disrupting mating, it reduces pest numbers, thereby protecting fruit trees such as apples and pears from damage.
