Elms are mostly leaf-eating pests, so corresponding control measures should be taken according to the occurrence characteristics and biological characteristics of pests. Such as inchworm, elm moth, elm moth and other phototropic pests can be trapped and killed by light; Physical control measures: For suspended animation and clustered pests, such as Ulmus pumila and Ulmus pumila, physical control measures such as artificial killing can be taken. Biological control can be carried out; When pests are difficult to control, appropriate chemical control should be taken to effectively control the harm and spread.

During the pest period, at the staggered positions on both sides of the trunk, gently scrape the L section of the dead epidermis with a length of l5cm into a semicircle, and apply 40% omethoate emulsifiable concentrate.

1, combined with forest tending, ploughing in winter, eliminating overwintering larvae and reducing the base of insect sources. Or when the elm tree begins to shed leaves in autumn, it should be cleaned up at any time to eliminate the larvae in the cocoon. 2, in the forest conservation management, timely cut off the branches and leaves that are harmful to spawning and early larva colony.
