Update on the situation of Aromia bungii in Germany
The red neck longhorned beetle Aromia bungii (Coleoptera: Cerambycidae – EPPO A2 list) was first found in Germany in July 2011 in a private garden in Rosenheim in southern Bayern (EPPO RS 2012/090), and again in 2016 in a nearby area in Rosenheim. Official measures have been applied since then with a few specimens found in 2019-2022 (RS 2017/056, RS 2020/192, RS 2023/110)).
In July 2023, one beetle was found in a bucket of water in a private garden and another in a pheromone trap within the buffer zone (only 60 m away from the infested zone). However no infested trees were found. From August 2023 until March 2024, eight trees have been felled within the demarcated area with larvae found in four of them, and five beetles caught in pheromones traps. One infested tree was found outside the infested area, resulting in the infested zone being extended by 3 ha. In 2024, three infested trees were detected, including one in the buffer zone. As of January 2025, 189 plants were found to be infested since the outbreak begun in 2011, the infested zone covers 213 ha and the total demarcated area 11900 ha. Official measures are applied including felling of infested and suspicious trees, public awareness raising in affected areas and official surveys. The duration of official measures was extended to 31 December 2028.
The pest status of Aromia bungii in Germany is officially declared as: Present at one location, under containment, in case eradication is impossible.
