The invention relates to bactrocera minax sex pheromone, and an extraction method and an application thereof. A main active component of the bactrocera minax sex pheromone provided by the invention is undecanol. The extraction method of the bactrocera minax sex pheromone comprises the steps of immersing bactrocera minax sex pheromone in a mating season in ethyl ether for 20 s-300 s; analyzing by using a gas chromatography-mass spectrometer to obtain chemical components of an extract liquid; and determining activities of the chemical components in the extract liquid by using a Y-type olfactometer. The bactrocera minax sex pheromone provided by the invention can be used as a sex attractant for monitoring field occurrence conditions of the bactrocera minax and disturbing mating of the bactrocera minax by mating disruption, and can be used as an attractant to trap and kill the bactrocera minax. The extraction method of the bactrocera minax sex pheromone is simple in operations, high in reproducibility and small in required bactrocera minax amount. Besides, a preparation period is short and result reliability is high.
