Aromia bungii Faldermann is widely distributed in China. From Liaoning, Inner Mongolia in the north, to Gansu, Shaanxi, Sichuan in the west, to Guangdong, Guangxi in the south, and in the east, Sichuan, Hubei, Hunan, and Jiangxi in the east. Harmful peach, plum, peach, cherry, plum, plum, apricot, Yu plum, weeping willow and other plants. The larvae enter the xylem and cause damage to the stems. The stems are hollow and the tree vigor is weakened. In severe cases, the plants can die. Peach trees generally live for about 30 years, but the peach tree's life span has been reduced to about 10 years, because the larvae feed on the trunk, weakening the tree vigor, and in severe cases can cause the whole plant to die.

Each side of the front of the chest has a spike, with a knob-like protrusion on the back. Coleoptera has a smooth surface, the base is wider than the anterior chest, and the posterior end is narrow. The male body is small and the frontal ventral surface is engraved. The tentacles have a length of 5 knots; the female has many transverse stripes on the ventral surface and the antennae have a length of 2 knots.
Eggs: long oval, milky white.
Larvae: The mature larvae have a body length of 50 mm, yellow-white, and 4 chloasma patches in the anterior half of the anterior thoracic column. Each front has a recess, and each of the lateral rims has a triangular shape.
? 蛹: Light yellowish white, with 1 protrusion on both sides of the front chest and the center of the front edge.
Living habits? In North China, one generation will be completed in two to three years. In Jiangxi, one generation will take place in two years, and a few will take three years, and one generation in each year. Winter larvae pass under bark and xylem tunnels. The following spring refreshment activities continued to drill irregular tunnels under the cortex and xylem, and discharged a large number of red-brown worms and debris, and piled up on the base of the trunk, which was the most dangerous from May to June. When severe, the trunk was hollowed out and died. The life span of the larvae is 50~60cm. From June to July, it emerged as an adult, and the adults that emerged from the feathers climbed on the branches and leaves for feeding. After mating, the eggs are prolific in the gaps between the bark of the trunk and main branches. The larvae feed on the bark after hatching. After diapause, the larvae continue to feed on the cortex until late July to August. The larvae head upwards. Feeding to the xylem, and then passing through the winter, aged 5 to 6 months old in the third year, mature into the adult.
?? Prevention methods??
1 After catching the adults of the adult P. erythropoda, during the period of adulthood from June to July, the habit of having resting branches of the adults from noon to 3 pm can be used. Organizing personnel to capture in the orchard can achieve better control. effect. ?
2. The white-stemmed tree trunk uses the white-tailed habit of the pink neck bengal. It coats the trunk of the peach tree and the main branch with white before adult emergence, so that the adult does not dare to lay eggs on the trunk and the main branch. The whitening agent can be prepared in the ratio of lime, sulfur and water in the ratio of 10:1:40; it can also be painted and dried with the precipitate of lime sulfur in the past. ?
3. Assassination larvae The larvae of P. erythropolis that hatched before September are foraging under the bark. At this time, small reddish-brown worms can be found on the trunk and the main branch. Once worms are found, sharp stalks are used to draw larvae. Bark is opened to kill larvae. It is also possible to inspect the branches in the spring of the following year. Once the branches are found with red-brown sawdust worms, the larvae in the xylem are excavated and killed with a sharp knife. ? 
It consists of host,bed extension, corridor display, door lamp, secondary host as well as optional modules (including music, bathroom extension) for realizing some peculiar functions.
