insect patient-oriented
pheromone and applications thereof, belonging to the technical field of
pest control. The Monochamus laternatus adult attractant based on
insect patient-oriented
pheromone is characterized in that a key component is 2-undecyloxy-1-
ethanol; auxiliary components consist of alpha-
pinene of purity 95% and
