National Invasive Species Awareness Week — Emerald Ash Borer

Posted on: February 28th, 2018 by Samantha Kahl

Hap­py Wednes­day! On this third day of Nation­al Inva­sive Species Aware­ness Week, we’re tak­ing a clos­er look at the Emer­ald Ash Bor­er (EAB).

Accord­ing to the NYS DEC, The EAB is a bee­tle from Asia that was first found in Michi­gan in 2002. Sad­ly, the EAB infests and even­tu­al­ly kills North Amer­i­can Ash tree species, mak­ing every native Ash tree sus­cep­ti­ble to infes­ta­tion.

Let’s get a clos­er look!

The EAB is very small, mea­sur­ing, at most, 0.5 inch­es long and 0.125 inch­es wide. The adults have a shim­mer­ing emer­ald green body with a cop­per or pur­ple abdomen on it’s under­side. You’ll often see these pests from May through Sep­tem­ber, but their prime activ­i­ty months are June and July. If you pass by an Ash tree, you will most like­ly see D‑shaped exit holes in the branch­es and trunk of trees. Oth­er signs of infec­tion include the yel­low­ing and brown­ing of tree leaves and less tree canopy present. With­in 2 to 4 years, the Ash trees will suc­cumb to the EAB infes­ta­tion.

The EAB is found through­out the East­ern to Cen­tral Unit­ed States and East­ern Cana­da. In New York, the first infes­ta­tion of EAB was sight­ed in Cat­ta­rau­gus Coun­ty in 2009. It then spread to the Hud­son Riv­er Val­ley, and con­tin­ued on to more than 30 coun­ties. Infes­ta­tions were most recent­ly found in Franklin and St. Lawrence Coun­ties in 2017.
