The present application belongs to the technical field of fruit fly prevention and control, and discloses a disorienting agent, a preparation method and application thereof. The disorienting agent contains rosemary extract and orange peel essential oil. The rosemary extract and orange peel essential oil contain terpenes and other compounds (such as 1,8-cineole in rosemary), which can compete with natural signal molecules to bind to odor binding proteins or olfactory receptors, which can cause fruit flies to fail to activate the correct nerve signal or directly block the signal transduction pathway. The orange peel essential oil in the disorienting agent has a strong smell, which can strongly cover or mask the weak smell signal emitted by the fruit, forming an "olfactory masking" effect, so that the fruit fly cannot find the fruit. Moreover, compared with sex pheromones as disorienting agents, which can only act on male fruit flies, the disorienting agent of the present application can interfere with the olfactory receptors of adult fruit flies to make them unable to find the target, so that they cannot accurately locate the oviposition site and harm the fruit. The disorienting agent is effective for both female and male fruit flies.
