(1) Brush off the insects on the branches with a hard brush or a fine wire brush, and combine with plastic pruning to cut off the severely damaged branches.

(2) Spraying 5 Baume lime-sulfur mixture or 5% diesel oil emulsion before germination in early spring.

(3) Protect natural enemies such as ladybug.

(4) Strengthen the quarantine of seedlings and scions to prevent spread.

(5) Spray control of nymphs in incubation period. Control time: the first generation. Prediction method: When a large number of adults are found to lay eggs in May, the branches of the female shell of Morinda citrifolia or the bark 10 ~ 20 section of the female shell of Morinda citrifolia are cut off at any time, dried in the shade, put into a glass tube, plug the nozzle with cotton, hang the glass tube on the crown out of direct sunlight, and observe whether there are nymphs on the tube wall every day. When it is found that there are dense nymphs crawling on the tube wall, it is the beginning of nymph hatching. Serious peach orchards should be sprayed for the first time in 5 ~ 6 days (when the hatching rate of eggs is about 50%) and sprayed for the second time in 5 ~ 6 days (when the hatching rate of eggs is above 90%). It was observed that eggs secrete wax hairs 4 ~ 5 days after hatching. When spraying, 0.2% wood vinegar or 0.2% kerosene can be mixed.
