Update on the situation of Aromia bungii in Japan

In Japan, Aromia bungii (Coleoptera: Cerambycidae – EPPO A1 List) was first found in 2013 in Honshu (Aichi prefecture) (RS 2013/188). Since then, the beetle spread to new areas in Honshu: it has been confirmed in Tokyo (municipality of Fussa, 2015), Saitama (municipality of Soka in 2014, and more than 150 sites in 2018), Osaka (11 municipalities), Gunma (municipality of Tatebayashi, 2015), Tochigi prefectures. It was also found on Shikoku (Tokushima prefecture) in July 2015. It was subsequently found in Honshu in Wakayama Prefecture in 2017, and in Nara Prefecture in June 2019. Local authorities are taking measures to prevent further spread of the pest and encourage early detection by citizens. In Tatebayashi city, a soft drink or 50 yen (≈0.4 euro) in cash is provided for each dead adult longhorn beetle brought in. More than 2 000 red-necked longhorn beetles have been collected so far under the initiative, according to Tatebayashi officials.

The situation of Aromia bungii in Japan can be described as follows: Present, only in some areas (Honshu and Shikoku).
