Asian Longhorned Beetle

Asian Longhorned Beetle (ALB) was first discovered in the United States in Brooklyn, New York, in Aug 1996.
ALB was later detected in Chicago, Illinois, in Jul 1998. In Oct 2002, the beetle was found in Hudson County, New Jersey, and then in Middlesex and Union Counties, New Jersey, in Aug 2004. In Aug 2008, ALB was discovered in Worcester County, Massachusetts, and in Jul 2010, ALB was found in Suffolk County, Massachusetts. In Jun 2011, ALB was detected in Clermont County, Ohio. However, in 2008, after the completion of control and regulatory activities, and following confirmation surveys, ALB was declared eradicated in Chicago, Illinois, and Hudson County, New Jersey.

Similarly, in 2011, ALB was declared eradicated from Islip, New York. So why should we be concerned?? Because of this pests diet. The Asian Longhorned Beetle has a long and growing list of hardwood host species in North America. While it seems to prefer maples and horse chestnut, it will readily attack yellow-poplar, willow, elm, mulberry, black locust, and several commercial fruit trees including pear and plum. ALB’s species preference leaves a majority of northern hardwood forests, western hardwood forests and most North American urban forests at risk.
