(Z)-11-Hexadecen-1-ol, as a key component or synergistic substance of sex pheromones in various important agricultural pests (such as the cotton bollworm and tobacco budworm), is synthesised and released by female-specific glands to regulate the directional behaviour of males. It has been developed through artificial synthesis techniques as a core component of pheromone baits, widely used in pest monitoring and mating disruption control systems for field crops like cotton and tobacco, achieving efficient and precise pest population control while reducing reliance on chemical pesticides, making it an indispensable technological means in modern green agriculture.
