(E)-8-Dodecen-1-ol is often isolated from female individuals of lepidopteran insects such as Grapholita molesta, and it is an important active component of the sex pheromones of these insects. It is widely used in the field of insect control, often used as a core attractive component to be compounded with other pheromone components into highly selective attractants. These attractants are used for population monitoring and green prevention and control of such pests in scenarios like orchards, which can accurately trap male insects to interfere with their mating behavior, while improving the accuracy of pest population dynamics monitoring and reducing the dependence on and usage of chemical pesticides.
