Z-8-dodecen-1-ol, as a key component or synergistic substance of the sex pheromone of several lepidopteran pests (e.g., codling moth and pear small heartworm), is released from the female gland to regulate the oriented behaviors of males, and it has been developed as a core component of the pheromone lure core through synthetic technology, which has been widely used in the monitoring of pests in orchards and the prevention and control system of mating disruption.
