The Asian longhorned beetle is an invasive species that is threatening Long Island’s trees. Recently, the U.S. Department of Agriculture (USDA) dedicated August as “Tree Check Month” to raise awareness and help eliminate the insect.

 

The USDA is asking residents in Nassau and Suffolk counties to check their trees for this invasive insect and the damage it causes. August is a critical time of year to look for the Asian longhorned beetles because it’s when people are most likely to see adult beetles.

 

 

“Checking trees for the pest and the damage it causes is how you can help us eliminate the beetle from the United States, and protect more trees,” said Josie Ryan, operations manager for the Asian longhorned beetle eradication program at the USDA. “The sooner we know where the insect is, the sooner we can stop its spread.”

The Asian longhorned beetle is an invasive wood-boring beetle that attacks 12 types of hardwood trees in North America, such as maples, elms, buckeyes, birches, and willows. Infested trees do not recover and eventually die. Infested trees also become safety hazards since branches can drop and trees can fall over, especially during storms. In its larval stage, the insect feeds inside tree trunks and branches, creating tunnels as it feeds, then adults chew their way out in the warmer months, leaving about 3/4-inch round exit holes.

 

The adult beetle has distinctive markings that are easy to recognize:

• A shiny black body with white spots that is about 1” to 1 1/2” long
• Black and white antennae that are longer than the insect’s body
• Six legs and feet that can appear bluish in color

Signs that a tree might be infested include:

• Round exit holes in tree trunks and branches about the size of a dime or smaller
• Egg sites that are shallow, oval or round wounds in the bark where sap might weep
• Sawdust-like material called frass found on the ground around the tree or on the branches
• Branches or limbs falling from an otherwise healthy-looking tree

The public has a vital role in helping to stop the spread of the ALB and eliminating it from infested areas.

 

How to help:

 

Report it: If you think you found a beetle or tree damage, report it by calling the ALB hotline at 1-866-702-9938 or submitting an online report at www.AsianLonghornedBeetle.com. Try to photograph the ALB or tree damage. If you can, capture the beetle in a durable container and freeze it, which helps preserve the insect for identification. Then report it.

 

Reduce spread: If you live in an ALB quarantine area, please keep the tree-killing pest from spreading. Follow state and federal laws, which restrict the movement of woody material and untreated firewood that could be infested.

 

It is possible to eradicate ALB. USDA and its partners eradicated the insect from Illinois, Boston in Massachusetts, New Jersey and portions of New York and Ohio.
