2. Comprehensive spraying control: all Chinese pine, Platycladus orientalis and Pinus bungeana are sprayed with pesticides once, and 40% omethoate, toxic zinc or pyrethroid pesticides are used, and the concentration is slightly higher than the instructions. For example, if 40% omethoate is used, the concentration is 800- 1000 times. Prevent adults from invading or killing adults.

3. Bait wood trapping. When the rate of damaged plants is less than 2%, bait can be set to trap and kill. The method is: before the invasion of Yang Fei, the dominant species or pioneer species, a small number of weak trees are cut down as bait, and the setting method adopts original strips or logs, and the number of baits within 800m2 should be 1-2. When the larvae do not pupate in the new sub-tunnel, the bait will be stripped and the larvae will be destroyed in June-July and August.

Extended data:

Beetles are mainly distributed in tropical, subtropical and temperate regions. It occurs in all provinces and regions south of Huaihe River in China. It mostly occurs in branches or fallen trees, storage granaries and equipment warehouses, endangering rice, dried potatoes and bamboo and wood equipment.

Beetles spread all over the northern and southern provinces of China, endangering Pinus massoniana, Pinus densiflora, Pinus armandii, Pinus tabulaeformis and Pinus sylvestris var. mongolica. Mongolian pine and black pine. Use adults and larvae to destroy twigs, branches or cut trees of pine trees. Any damaged tip is easily broken by the wind. This insect is very harmful to Pinus massoniana in Guangzhou Baiyun Mountain Scenic Area.

Breeding 1 generation every year, overwintering as adults and overwintering in different places in the north and south. In the south, adults overwinter in damaged branches. Overwintering adults leave the overwintering site from late March to mid-April of the following year, invade the pith of pine branches to supplement nutrition, and then build holes, mate and lay eggs on healthy treetops, weak trees or newly felled trees.
