It was just over a year ago that Anoplophora glabripennis (Asian longhorned beetle or ALB) was first reported in Worcester, MA. Since that time, local, state, and federal entities have joined together to fight the infestation of an invasive pest that has caused negative impact to the City of Worcester and placed the Commonwealth as well as the entire Northeastern United States on high alert. The following tree species are considered to be good hosts for the ALB:

Acer (maple)

Aesculus (horsechestnut)

Betula (birch)

Platanus (plane-tree)

Populus (poplar)

Salix (willow)

Ulmus (elm)

Other susceptible trees include: Fraxinus (Ash, especially green ash, F. pennsylvanica), Albizia (silk tree), Celtis (hackberry), and Sorbus (mountain ash). A complete list of host species is available by clicking here.
