History and Economic Importance

Asian Longhorned Beetle thus far has been attacking maple, horsechestnut, poplar, and other trees in the urban and suburban area of New York and Long Island. Timber, nursery stock, shade tree and maple syrup production are all at risk. According to the Empire State Forest Products Association, these industries employ more than 60,000 people. As an exotic, the beetle is expected to encounter few natural enemies. This factor will influence a rapid expansion of populations by natural means.
