Autumn shoot damage rate of 52.1-100%, economic losses of 24.9% or more. According to the biological characteristics of pests and hosts, four comprehensive measures were taken to change the ecological conditions of pests, coordinate the use of scientific management tips, adjust the tips, protect and utilize natural enemies, and pick the agents.
