Emerald ash borer continues to threaten Delaware trees

DOVER, Del. — Emerald ash borer (EAB), a destructive insect from Asia that attacks and kills ash trees, has been confirmed in Newark, Delaware.

Emerald ash borer found at new Delaware sites

Emerald ash borer (EAB), a destructive insect from Asia that attacks and kills ash trees, has been confirmed at two additional sites in Delaware: one near Middletown, New Castle County, and another near Seaford, Sussex County. Originally found in northern Delaware in 2016, the new detections create added urgency for homeowners and municipalities to determine if they have ash trees on their property and decide on possible management options. Current guidelines recommend the removal or treatment of ash trees if located within 15 miles of a known infestation. Because Delaware is geographically small and EAB can go undetected for years, residents are urged to educate themselves now and take action.

“Flying colors”: Delaware passes annual aerial forest health “check-up”

In late-June, Delaware’s forests get an annual “physical” or “check-up” – just after spring’s “leaf-out” blankets the state in a wave of green color. Just as people should visit the doctor to be screened for potential diseases, trees are examined with a variety of tools to hopefully spot minor issues before they turn into major ones.

Armed with a digital camera, GPS technology, and a tablet equipped with specialized software and satellite data, forest health specialist Bill Seybold boards a small plane for a sky-high view of the First State. The annual aerial survey is specifically designed to detect potential threats that can only be seen from the air. Fortunately, early results from the 2018 aerial forest survey indicate no major outbreaks of tree diseases or insect pests.
