Spotted Lanternfly Quarantine Expanded in Pennsylvania - What Does That Mean For Ohio

Published on

Earlier this week, the Pennsylvania Department of Agriculture (PDA) announced the expansion of the Pennsylvania's Spotted Lanternfly (Lycorma delicatula) (SLF) Quarantine to include 12 additional counties, bringing the total number of  quarantined counties to 26. Two of the counties (Beaver and Allegheny) that have been recently added, are located in western PA, with Beaver County neighboring or adjacent to Ohio's Columbiana Couty.


For reference, a copy the information included in the PDA release distributed on March 3, 2020 is included at the bottom of this alert.


You may be wondering, what does this mean for Ohio. Since the detection of  SLF in Pennsylvania in September of 2014, Extension Professionals have been spreading the word about this invasive insect and urging Ohioans to become familiar with this pest, its life-cycle, the host plants it prefers, and to be on the look-out for it. This message has not changed. The SLF is currently in the egg mass stage. The eggs were laid in fall of 2019, and will hatch in the spring of 2020. The egg masses can be laid on a variety of surfaces including trees, posts, decks, outdoor furniture, metal drums, vehicles, trailers, rail cars, just to name a few. 


What we are encouraging Ohioans to do, is look for SLF egg masses. Early detection is the first step in response efforts. I recently heard someone say "if you see something, say something." Today's alert will be focusing on the egg masses, with additional alerts to come. 


Below are a series of photos of the egg masses. It is important to note, as they age their color and appearance can change.

The SLF egg masses in the photo above were laid on a rock. You will notice the actual eggs aren't visible as above and have been covered by a waxy-like substance. It has been described as mud-like in appearance.

The SLF egg masses in the photo above were laid on a rusty barrel. Again you will noticed that the eggs are covered. The actual color can fade and age over the winter.


If you begin looking for SLF egg masses, and find something that you suspect maybe an egg mass of the SLF, mark the location, take pictures, and contact your local Extension office, or the Ohio Department of Agriculture, Division of Plant Health at 614-728-6400.


While the focus currently is on the egg mass stage, below is an illustration of the SLF's life-cycle. Stay tuned for seasonal updates in BYGL and information about other OSU Extension Resources coming online soon.

Information included below was taken directly from the Pennsylvania Department of Agriculture press release. Information about permits and compliance agreements are specific to PA. There is currently no quarantine, permits or complaince agreements in Ohio because the SLF has not yet been detected in the buckeye state. 


Department of Agriculture Adds 12 Counties to Pennsylvania’s Spotted Lanternfly Quarantine


(03/03/2020) Harrisburg, PA – Agriculture Secretary Russell Redding today announced that twelve counties have been added to Pennsylvania's Spotted Lanternfly quarantine zone ahead of the 2020 spring hatch. With this addition, the quarantine for this invasive pest is now at 26 counties.


"The Spotted Lanternfly is more than a pest in the literal sense," said Agriculture Secretary Redding. "It's wreaking havoc for home and business owners; kids who just want to play outside; Pennsylvania agriculture and the economy of the state we all call home. Whether you think it's your job or not, we need every Pennsylvanian to keep their eyes peeled for signs of this bad bug – to scrape every egg mass, squash every bug, and report every sighting. We need to unite over our hatred for this pest for our common love: Pennsylvania."


The new dozen counties are not completely infested, but rather have a few municipalities with a known infestation which led to a quarantine being placed on the entire county out of an abundance of caution. Allegheny, Beaver, Blair, Columbia, Cumberland, Huntingdon, Juniata, Luzerne, Mifflin, Northumberland, Perry, and York have been added to the quarantine for 2020.


"Most of these municipalities have already been aggressively treated," said Dr. Ruth Welliver, director of the Bureau of Plant Industry. "With continued aggressive treatment and monitoring, and an actively engaged community, we can strike Spotted Lanternfly from these counties."


Quick, aggressive treatment to newly identified populations of Spotted Lanternfly in Pennsylvania was funded through the Rapid Response Disaster Readiness line of Governor Wolf's 2019 PA Farm Bill. The 2020 PA Farm Bill proposes another $3 million to combat Spotted Lanternfly, plus an extra $1 million that is uncommitted to readily act in the event of the next agricultural disaster.


Businesses that operate in or travel through quarantined counties are required to obtain a Spotted Lanternfly permit; fines associated with noncompliance can be up to $300 for a criminal citation or up to $20,000 for a civil penalty. Homeowners with questions about treatment are encouraged to contact their local Penn State Extension office or learn about management, including approved sprays. Pennsylvanians who live inside the quarantine zone should also review and sign the Compliance Checklist for residents.
