The Asian longhorn beetle musk ( Aromia bungii ) is a native to China beetle art and belongs to the family of longhorn beetles . It is considered a wood pest and was probably brought into the area around Rosenheim and Kolbermoor in the area around Rosenheim and Kolbermoor via vegetable packaging material, especially packaging wood, but also possibly plants or wood .
Features and way of life
The adult beetles are between 25 and 40 mm long. With an otherwise similar habitus, striking distinguishing features from the European muskbok are above all the red pronotum, but also the lacquer-like, black, glossy body color.
The beetles particularly infest previously damaged trees of the Prunus genus . These serve as breeding trees on which the 6–7 mm long eggs are laid by the females in bark depressions. In some cases, healthy trees are also attacked. The larvae hatch very quickly and create so-called galleries in the sapwood within two to three years . They seldom penetrate into the heartwood. Pupation takes place just below the bark in a pupa cradle. In the final stage, an oval exit hole about 12 mm in diameter is gnawed, from which manure and drill dust are also pushed. This can be used as an indicator of an infestation.
damage
Since the hatched beetles can attack the same tree again, the damage caused by the extensive galleries can be considerable. Parts of the bark can peel off, which in some cases even leads to the tree's death. As a result of the injuries, fungi that cause wood rot can easily penetrate and further damage the tree. Since the potential for damage is estimated to be considerable, wood quarantine zones were issued around the occurrences identified at Rosenheim and Kolbermoor, from which no wood from deciduous trees may be taken. The beetle was added to the Eppo- A1 list (quarantine pests).
