Control methods 1. In the period of adulthood from June to July, it was generally not more than 10 days in a peach orchard, and it was relatively neat. During this period, adults were patched and the effect was greater. The people of Huailai County in Hebei Province discovered that the pink neck beetles from the crown to the base of the trunk from 12 to 13 o'clock, cluster rest, artificially catching adults at noon or afternoon, for several days, can basically control the damage. 2. In the period of 9~10 months when checking the stems for fresh insects, the subcutaneous larvae should be excavated and eradicated with a knife or scissors immediately. The best results are obtained. 3. Before adult occurrence, apply white to the trunk and the main branch to prevent adults from spawning. Whitener: Use 10 parts of quicklime + +1 part sulfur powder + 10 parts water + a little salt. 4. Insert alumina tablets (containing 0.075g active ingredient) or dichlorvos (20x) into each fistula and then seal it with yellow mud to kill the larvae.
