The damage caused by the Red Palm Weevil is expanding!

The damage caused by the invasive species, the red-banded longhorn beetle, is expanding nationwide, and damage has also occurred in neighboring cities. We ask for your cooperation in prevention efforts to stop the spread of this damage.
The red-banded longhorn beetle is an invasive insect that parasitizes trees in the rose family, such as cherry, plum, and peach, with its larvae burrowing inside the wood.
If the damage progresses, the trees may die, which could have serious impacts on tourism and agriculture, as well as potential secondary damage from fallen trees.

The larvae feed inside the trees from around April to October, spending 2 to 3 years while excreting a large amount of minced frass (a mixture of larval droppings and wood shavings). They emerge as adults from around May to August.
The adults are characterized by a body length of about 2.5 to 4 centimeters, a shiny black color overall, and a red thorax (neck area).

This type of frass is characterized by a large amount of wood chips, and immediately after being excreted, it often appears connected in stick-like or karinto-like shapes.
The frass varies in thickness from about 1mm to 5mm, proportional to the size of the larvae.

If you find a red-banded longhorn beetle

If you find one, please cooperate in extermination by crushing it on the spot to prevent the spread of damage, and also provide information to the Living Environment Division Environmental Conservation Section or the Environment Department Environmental Policy Section.
Additionally, since the red palm weevil was designated as an invasive species on January 15, 2018, it is prohibited to keep or transport it alive.
