1,7-dioxaspiro[5.5]undecane, as a key component of the sex pheromone of dipteran pests such as Bactrocera oleae, is released by males to attract females to complete mating behaviour. It has been developed through artificial synthesis into a specific lure core and is widely used in the monitoring and trapping systems for fruit flies in olive groves and orchards. By precisely interfering with the reproduction process of pests, it significantly reduces the incidence of pest damage to fruit and has become the core technical method for the green prevention and control of olive pests in the Mediterranean region.
