Japan Sets Up Invasive Beetle Task Force as Red-Necked Longhorn Spreads to 20 Prefectures

Japan’s agriculture minister Norikazou Suzuki called on the public on August 2 to kill the invasive red-necked longhorn beetle (クビアカツヤカミキリ) on sight. The black insect with distinctive red chest and long antennae has spread to 20 prefectures, causing severe damage to cherry, plum, and peach trees. The government established a task force with the environment ministry to develop a national prevention strategy.

Why the beetle is a national threat

The red-necked longhorn beetle damages Rosaceae family trees including cherry, plum, and peach. The larvae bore into tree trunks, causing trees to wither and eventually fall. First confirmed in Aichi Prefecture in 2012, the beetle has now spread across 20 prefectures nationwide. Suzuki announced the task force on his X account, where the post received over 8,000 likes.

Government response and public action

Agriculture Minister Suzuki and Environment Minister jointly established a task force on August 2 to develop prevention strategies and coordinate efforts across ministries and local governments. The minister urged citizens to crush or kill any beetles they find. Some local governments offer bounties for dead beetles brought to their offices. However, transporting live beetles is prohibited by law since the species is designated as an invasive alien species.

How to report and handle the beetle safely

Citizens who find the beetle should kill it rather than capture it alive. Dead beetles can be brought to local government offices in some areas to claim bounties. For questions about proper handling, residents should contact their local municipality. The government emphasizes that appropriate disposal is essential to prevent further spread of this destructive pest.

Final Thoughts

Japan faces a spreading beetle crisis that threatens iconic cherry blossoms and fruit crops across 20 prefectures. The government’s task force signals serious intent, but success depends on public participation in killing and reporting sightings.
