It is found that there are caves in the trunk, which can be blocked with cotton wool, or painted with mud mixed with lime powder and sulfur powder, and can also be irrigated with 500 times 800 times liquid dimethoate, so as to kill the eggs of overwintering insects. The underground part (including basin soil) can be diluted and irrigated with a mixture of dimethoate and dichlorvos.
