Damage caused by red-necked longhorn beetles is spreading!

Damage caused by the specified invasive species, the red-necked long-horned beetle, is spreading across the country, and damage has also occurred in neighboring cities. Please cooperate in preventing the damage from spreading.
The red-necked longhorn beetle is an invasive insect that parasitizes trees of the Rosaceae family, such as cherry, plum, and peach, and its larvae eat away at the inside of the tree.
If the damage progresses, trees will wither and die, which will have a serious impact on tourism and agriculture, and secondary damage from fallen trees is also predicted.

The larvae feed inside the tree from April to October, spend two to three years excreting large amounts of minced frass (a mixture of larval droppings and wood chips), and emerge as adults from May to August. Appears outside the tree.
Adults are approximately 2.5 to 4 cm long, shiny black overall, and characterized by a red thorax (neck).

This species of frass has a lot of wood chips, and is characterized by the fact that they are often connected in a rod-like or karin-like shape immediately after being discharged.
The frass is proportional to the body size of the larva, and can vary in thickness from 1 mm to around 5 mm.
