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 measures to stop the spread of this damage.
The Red-Banded Leaf Beetle is an invasive insect that parasitizes Rosaceae trees such as cherry, plum, and peach, with larvae that burrow and damage the wood.
As the damage progresses, the trees will wither, which will have a serious impact on tourism and agriculture, and secondary damage from fallen trees is also anticipated.
The larvae feed inside the trees from April to October, spending 2 to 3 years while excreting a large amount of minced frass (a mixture of larval droppings and wood shavings), and emerge as adults outside the trees around May to August.
The adult is characterized by a body length of about 2.5 to 4 centimeters, overall glossy black color, and a red thorax (neck).
This type of frass is characterized by a large amount of wood chips, and immediately after being discharged, it often connects in rod-like or karinto-like shapes.
The thickness of the larvae varies from about 1mm to 5mm, proportional to the size of the larvae's body.
If you find a red-banded longhorn beetle
If you find it, to prevent the spread of damage, please cooperate by crushing it on the spot, and also provide information to the Living Environment Division Environmental Conservation Section or the Environment Department Environmental Policy Section.
The Red Palm Weevil has been designated as a specified invasive species as of January 15, 2018, so keeping or transporting it alive is prohibited.
