(E)-5-Decene-1-yl acetate is a key component of sex pheromones for various pests in the families such as the Curl Moths and the Borers (e.g., the pear fruit moth and the codling moth). It is synthesised and released by female-specific glands to attract males for mating. Currently, it has been developed into an efficient biomimetic attractant through artificial synthesis techniques and is widely used in monitoring and trapping pests in orchards and fields, as well as in mating disruption strategies. By precisely regulating insect reproductive behaviour, it significantly reduces the use of chemical pesticides and has become one of the core technologies for integrated pest management in modern sustainable agriculture.
