The invention discloses a disorientation agent for disturbing mating of pinus sylvestris and application, and belongs to the technical field of prevention and treatment of forestry pest pinus sylvestris. The component of the disorientation agent is trans-11-hexadecene-1-alcohol acetate, and the disorientation effect of the disorientation agent is superior to that of the pheromone disorientation substance of the pinus sylvestris with the same dosage. According to the isotropic agent, 100-200 mg of trans-11-hexadecene-1-alcohol acetate is dissolved in liquid chlorinated paraffin and added into a polyvinyl chloride (PVC) capillary tube, 30-60 isotropic filaments are arranged per mu, the forest lasting period is longer than 3 months, and the isotropic rate is larger than 90%. The isotropic agent can obviously interfere with the mating between the male and female pinus sylvestris, is safe to the environment and natural enemies, is simple to operate, can be used for preventing and treating the ...
