Anoplophora glabripennis

EPPO code

ANOLGL

Common names

English name: Asian Long-horn Beetle
Nordic names: Asiatisk træbuk (DK)
Estonian name: Aasia sikk

Major host plants

Populus spp. are the most important hosts. Other known hosts: species of Acer, Alnus, Malus, Morus, Platanus, Prunus, Pyrus, Robinia, Rosa, Salix, Sophora, Ulmus, Betula, Fraxinus, Liriodendron tulipifera and Morus alba. It has not been recorded on conifers, Fagus or Quercus.

Symptoms

Resin bleeds from oviposition holes and larval tunnels in the bark. Larvae form galleries under the bark and tunnels in the wood. Masses of wood shavings extruding from round exit holes are also signs that adults have emerged. Piles of wood shavings collect at the base of infested trees.

Biology

Similar to Anoplophora chinensis.

Major pathway(s)

Transport of infested material (especially wood packing material) by man. Natural infestations spread slowly.

Detection and inspection

Attack by larvae is recognized by holes and tunnels in wood. Pay attention to wood shavings under tree and large holes (6-12 mm wide).

Pest status and importance

In Europe, particularly the Southern area, there is a risk of introducing A. glabripennis by the same pathway as it was introduced into the USA, by infested wooden packing materials from China. Structural weakening by the larvae of trees in urban regions poses a danger from falling branches.
