(Z)-Oxacyclotrideca-4-en-2-one is a macrolide lactone that functions as a sex pheromone in several moth species, including the peach fruit moth (∗Carposinasasakii∗). It is used in pest management to monitor and control populations of these moths by disrupting mating and trapping them, thereby reducing damage to crops like apples, peaches, and plums.
