Hemlock-killing pest, Hemlock Woolly Adelgid, found in new areas in Ohio

COLUMBUS — The Ohio Department of Agriculture and the Ohio Department of Natural Resources verified the discovery of a hemlock-killing pest in Lawrence, Monroe and Vinton counties in southeast Ohio.

Hemlock Woolly Adelgid is a small, aphid-like insect native to Asia that threatens eastern hemlock and Carolina hemlock in the eastern United States.

HWA was first reported in the eastern United States in 1951 near Richmond, Va. By 2005, it was established in portions of 16 states from Maine to Georgia, where infestations covered about half of the range of hemlock.

Locations in Ohio

The infestations were recently detected by ODA and ODNR officials in Dean State Forest in Lawrence County, Zaleski State Forest in Vinton County, and in a landscape setting in Monroe County.

Officials have been conducting surveys in the newly detected areas to determine the scope of the infestations.

The insect is primarily transmitted by wind and birds. Officials believe the new findings in Ohio are the result of natural spread from nearby areas where the pest is established.

There are now six counties in Ohio where hemlock woolly adelgid has been detected in a naturally occurring stand of hemlock.

In 2012, infestations were found in Meigs and Washington counties, and an infestation was detected in Hocking County in 2013.

Quarantine expanded

At this time, ODA will move to expand its hemlock quarantine, enforced by ODA’s Plant Health division, to include Lawrence, Monroe and Vinton counties.

Ohio quarantine regulations restrict the movement of hemlock materials from counties known to be infested into non-infested Ohio counties.

Ohio’s quarantine law also requires hemlock materials grown in non-infested counties in quarantined states to be inspected before being shipped and have a phytosanitary certificate verifying that the plant material is free of hemlock woolly adelgid when entering Ohio.

    Great! …yet another “benefit” of the globalists’ international irresponsible trading policies.

    why do we get all these pests from Asia destroying our forests, plants, and animals?

    who in blazes is responsible for this devastation?

    we pay billions for state and federal “alphabet soup” agencies tasked to prevent this sort of invasions, we pay import/export fees, inspections, tracking, tracing…but we seem to come up short always in getting these pests.

    why? who is responsible?

    If I contaminate a creek while I farm, Fed and Ohio EPA are all over me. why do these foreiners get a “pass?”
