Jersey City Trees Replaced as Part of Asian Longhorned Beetle Control Efforts
|For Immediate Release: July 2, 2003||Contact:||
More than 450 trees removed due to an Asian longhorned beetle infestation in Jersey City are being replaced as part of ongoing state and federal efforts to eradicate the destructive insect, Agriculture Secretary Charles M. Kuperus and Department of Environmental Protection Commissioner Bradley M. Campbell announced today.
"The Asian longhorned beetle is a major threat to New Jersey's maple and other hardwood trees," said Secretary Kuperus. "The removal of infested trees, as well as potential host trees in the affected area, was the most effective way to protect our residential forests. We're pleased those trees now are being replaced with non-host species that further our ability to control this dangerous insect."
"It is imperative that we take prompt action to control invasive species, such as the longhorned beetle, and other threats to forest resources," Commissioner Campbell said. "Federal and state foresters are to be commended for acting quickly to prevent this damaging pest from spreading."
The Asian longhorned beetle was first detected in Jersey City in October
on a largely commercial site located north of the Newport Parkway and
east of Washington Boulevard. Through a cooperative state and federal
control effort, 113 infested trees and 348 potential host trees were removed
from the area earlier this year.
In addition to the Jersey City tree removals, more than 1,000 potential host trees in Jersey City and Hoboken were treated with the insecticide Imidacloprid to prevent the beetle from spreading. A quarantine remains in effect in portions of Jersey City and Hoboken within a 1.5-mile radius of the affected site. It prohibits the movement of firewood, green lumber, and other living, dead, cut or fallen material - including nursery stock, logs, stumps, roots and branches - from potential host trees from the quarantined area.
State and federal agricultural officials are optimistic these efforts have successfully controlled the insect. Nevertheless, they urge the public to be alert for signs of the beetle, which typically emerge from a period of winter dormancy in late June to early July.
The beetles are about 1 to 1-1/2 inches long, are black and shiny with white spots, and have long distinguishable antennae that are banded with black and white. They attack many different hardwood trees, primarily maple but also horsechestnut, willow, elm and boxelder.
To lay her eggs, the female beetle chews small oval or round niches
in the outer bark of the tree. When immature worm-like beetles hatch,
they bore into trunks and branches and create immense tunnels for themselves
inside the trees. The adult beetles chew their way out, usually in late
spring or early summer, leaving round exit holes about the size of a dime
in their wake.
