Yes and may be considered "the" bad thing. It's centered in eastern PA. Last year's PA quarantine did not prevent the spread as it's been detected in surrounding states including DE, NY, MD, NJ & VA. Not all counties are affected in those states where it's been detected. Tree of Heaven is the favored host. I've been in the process of taking out any tree of heaven I find on my property. This pest sucks on the sap of trunks, shoots, and leaves. I know a vineyard manager in PA that is incredibly worried about the pest as he's near ground zero.

First one in Maryland has been confirmed today. A trapped male. Lots of hope that this is a random catch and doesn’t indicate that they have crossed into MD but seems like wishful thinking at this point.

I live within a few miles of the epicenter. Hope is not going to stop this critter. They reproduce in the millions and they're on the way. CT and Mass should have a few years to go unless some are accidentally transported. They're reportedly quite a potential problem for orchards and vineyards, especially "organic". Insecticides have been somewhat effective but with limits as sprayed areas repopulate after the residues attenuate. The bugs and their nymphs are large and difficult to miss. Smashed bugs can be seen all over the local roads.

They showed up on my property in a wave last year. Fewer this year (woodland) because we're short on preferred plant species. If there's a breakthrough in fighting them, it should probably happen in Berks County, PA where the problem started in 2014 and research is ongoing.

Recent summary update to this pest ........... https://www.goodfruit.com/spotted-lante ... pe-threat/ . Just got back from the quarantined area in PA and most vineyard owners are keenly aware on what to look for. Eggs masses are burned off with propane torch and the nymphs and adults are sprayed with insecticides. Have been eliminating tree-of-heaven saplings in disturbed areas around the vineyard. I know it's coming and it's now a matter of when and whether some softer remedies are possible when that time comes. I'm pulling for the folks in PA to get a strategic plan in place to share with others on how to minimize the risk.

Sticky tape is apparently not the answer. http://www.mcall.com/news/breaking/mc-n ... story.html

Numbers seem down considerably this year, at least in my tiny corner. The Sweet Bay Magnolia trees were loaded with them last year. Much fewer this year....so far. Right now they're in the nymph stage. This critter is about the size of a pencil eraser.

Image

Locally, they seem to have migrated like a front of thundershowers. The front was massive and then it slowly thinned out behind it. Numbers are probably still big in areas of specific target plants. The wave hit here 2 years ago. Last year was the first hatching and fairly substantial. This year is the 2nd.

Richard - Hopefully that front blows out to sea. After talking to vineyard colleagues in PA it's clear that quarantines are not successful. They seem to hitch hike on anything.....especially vehicles. My spouse and I are on the lookout and I have to keep pulling out tree of heaven saplings in the disturbed soil areas along the woods. Hopefully enough time passes before I spot them and the mid-Atlantic folks have a chance to set a control strategy for the rest of us to follow. Nuking everything is not an option in my mind.

Unless some sort of natural based defense comes in to play (molds, bacteria, virus, predators, etc.), I'm not confident that a manmade strategy will work. Perhaps it will on a smaller scale for individual vineyards, orchards, etc.

The wave was unmistakable here. One day there were no lanternflies and the next, you couldn't walk 20 feet without seeing a few, another 20 feet a few more...for miles. I get the feeling there will be fewer again this year in the woods...but we're short on preferred plants.

As a quick update (and a tiny N = 1 sample size), the number of Lanternfly nymphs is WAY down here. 30+ acre woodlot and very short of target species. Nymphs were swarming all over two Sweet Bay Magnolias last year, hundreds of them. This year...I've seen one.

No explanation, other than Magnolias must not be a target species and that once the massive adult wave blew through...future generations require something different in order to thrive in high concentrations, i.e.: habitat, environment, and/or food source.

Maybe the population will erupt again later in the Summer with a new influx of adults. I won't miss it if it doesn't happen.

The epicenter in District Township, PA (Berks County near Huffs Church and Bally, PA) is 10 miles west of here.

https://www.readingeagle.com/news/artic ... e-in-berks July 8, 2019

“When you go out and see several thousand lanternflies swarming a tree and the honeydew is falling on you like rain, it's scary,” said Sherburne, who chairs the Berks County Conservation District board of directors. “Never saw it before.” This summer, however, the spotted lanternflies seem to be gone. Sherburne wonders if it's some sort of cycle of the insect. “I haven't seen a nymph yet. It's wonderful,” she said. “I'm really interested in seeing if we get lanternflies coming through in another wave or if it was just a once-and-done thing.”

In Lower Alsace Township, Mark Goodwin expected to find nymphs this spring crawling on the front of his house, the shrubs and a large tree in his yard, like they did a year ago. This year he was ready for them, armed with spray bottles, sticky bands for trees and a Bug-A-Salt, a salt gun for killing flying insects that's found in sporting goods stores. “I was expecting to unleash World War IV on them,” he said. So far, Goodwin hasn't seen any in his yard. He lives near Little Antietam Park, where the fungi were found to kill them, so he theorizes that nature cut down the bug's numbers this year. “Really amazing. I haven't seen one,” said Goodwin. “I feel a little left out.”


Their observations remain similar to here. There were several hundred (maybe a thousand or more) in the trees and shrubs close to the house last year. This year....2 nymphs.

By now, based on the past 2 years, there should be thousands of adults flying around.

We had one in the garage and one flew in the house. That's it for the adults I've seen. Outside, none. None on the Sweet Bay Magnolias. Whatever the alleged natural fungus or microbes are, it's knocked the hell out of them.

I've heard reports of "waves" in the Lehigh Valley and Central/lower Bucks County that are comparable to what we saw last year. There're a number of vineyards and wineries in the Lehigh Valley and Bucks County.

Researchers are reportedly working diligently. There should be a bunch of data collected and available over the next few months.

Chester County is started to see increase levels. We have had only a few (knock on wood) but friends 4 miles away have many more than last year. Went bird watching up in Berks County earlier in the week. Not many on the trees at ground level but when you were focused on the tops of the trees with binoculars, they were flying all over the place.

WSJ had an article on this today. There was a video of a tree totally covered in these, at a small airport. I really hope they contain this. I cant imagine having this in my neighborhood.

Sadly, I don't believe there's any containment. Huge numbers in the Lehigh Valley. It's kind of bizarre because locally the numbers are still way down, minus 90% or more. They're definitely not absent but not everywhere like they were. The populations can fluctuate dramatically within just a few miles. Yesterday during a bike ride, one landed on the back of a friend while we were riding at about 10 miles per hour. He didn't notice and I swatted it off. It's that easy to move them from one location to another.

Just chatted with the produce farmer up the road about 5 miles, slightly closer to the epicenter. They've seen maybe 10 Lanternflies all Summer. That's dumbfounding considering the thousands a couple years ago. They have orchards of apples, plums, peaches and pears. They also grow strawberries, blueberries, raspberries and a wide variety of green vegetables. No Lanternfly damage worth noting.

The farmer's wife mentioned how the critters are supposed to be hard on grapes and grape vines....but they don't grow grapes.

For reasons I don't really understand, the local demand for wine grapes currently outstrips supply. Quite a few new vineyards have sprung up.

From July 2019: "Clover Hill Vineyards & Winery has been proudly growing grapes and producing wine in Pennsylvania for the past 34 years. This business is not only our livelihood, but it is our passion,” said Kari Skrip, owner of Clover Hill Vineyards and Winery. “We have six vineyards located in Lehigh and Berks counties, and the lanternfly has created a serious threat to our vineyards. While we haven’t experienced any direct damage to our vines, we have witnessed large populations of this invasive pest in our vineyards."

Clover Hill is < 10 miles from the epicenter. Plenty of Lanternflies there this year and last year.

Looks like we'll need to wait until next year for more data....but doom & gloom might be premature at this point.

Or is it the Asian longhorn beetle, hemlock woolly adelgid, or sudden oak death. Where is the extinction of trees thread?

This little bugger scares me. The length of your fingernail.

Image

https://phys.org/news/2019-09-ash-tree- ... erald.html

A dozen 60ft+ tall trees at the road frontage of our property are now dead. The Power Company is asking to take them down. Hoping the critter doesn't spread further in to the woods...as there're hundreds of target trees that they could wipe out.

Sudden oak death is no picnic. Fairly sure it's actually some kind of blight that's killing the Pin Oaks here. Something's not right when maybe 25% of the biggest trees (100 - 150 years old) die in just the past 5 - 10 years.

Yeah, we already kissed our ash goodbye in Ohio. Not to mention our elms, chestnuts, and butternuts, so I didn't include that. 1/3 of our forests are already gone from those. Asian longhorns will supposedly wipe out all softwoods, including most maples.

I missed this when originally published. Treating two areas in MD for spotted lanterfly.

Spotted Lanternfly treatments begin in Cecil, Harford counties
MDA found a small population of spotted lanternfly in these two areas
PUBLISHED ON SEPTEMBER 9, 2019


The Maryland Department of Agriculture is working with the U.S. Department of Agriculture (USDA) to treat for spotted lanternfly at multiple sites in the upper northeast corner of Cecil County and along the northern border of Harford County. The Maryland Department of Agriculture found a small population of spotted lanternfly in these two areas while surveying for the invasive pest this spring and summer.

ANNAPOLIS, Md. — The Maryland Department of Agriculture is working with the U.S. Department of Agriculture (USDA) to treat for spotted lanternfly at multiple sites in the upper northeast corner of Cecil County and along the northern border of Harford County. The Maryland Department of Agriculture found a small population of spotted lanternfly in these two areas while surveying for the invasive pest this spring and summer.
“Even before the first spotted lanternfly was confirmed in Maryland last October, the department and our partners had been vigorously surveying and educating the public about this pest,” said Maryland Agriculture Secretary Joseph Bartenfelder. “Due to its potentially devastating effects on the agriculture industry, treating for this invasive insect now is critical to controlling its spread in Maryland and protecting our state’s agricultural commodities.”
The USDA will work with a contractor to treat Ailanthus altissima, more commonly known as tree-of-heaven, in a quarter-mile radius of where the department found spotted lanternfly during surveying. Ailanthus altissima is the spotted lanternfly’s preferred tree to feed on and research has shown it is required for spotted lanternfly reproduction.
“We’re working with Maryland Department of Agriculture to contain, control, and suppress the isolated spotted lanternfly infestations in Cecil and Harford Counties,” said USDA’s State Plant Health Director Matthew Travis. “Detecting the pest early, while the population is small, is critical to stopping its spread. That’s why we’re asking the public for help. If you see spotted lanternfly or find egg masses, call MDA or an Extension office.”
Treatments are administered under USDA supervision. Depending on the size of the tree, there are two treatment types. Ailanthus altissima less than six inches in diameter at breast height (DBH) will receive herbicide treatments and Ailanthus altissima with a DBH greater than six inches will be treated with systemic insecticide. Both the herbicide and the insecticide have been found to have no or very minimal health effects on humans and pets.
All property owners in the treatment area have been, or will be, directly notified prior to spraying. Treatments will be completed by the end of September and will resume in the spring.
The spotted lanternfly poses a major threat to the region’s agricultural industries as it feeds on over 70 different types of plants and crops – including grapes, hops, apples, peaches, oak, pine, and many others. Originally from Asia, the spotted lanternfly is non-native to the U.S. and was first detected in Berks County, Pennsylvania in the fall of 2014. As a known hitchhiker, the spotted lanternfly has spread to 14 counties within Pennsylvania and has confirmed populations in Delaware, Virginia, and New Jersey.
The department’s Plant Protection and Weed Management Program continues to work with USDA, the University of Maryland Extension, the USDA Animal and Plant Health Inspection Service (APHIS), Plant Protection and Quarantine (PPQ), and others to monitor the insect in Maryland. Our department has also launched outreach and education campaigns aimed at agricultural operations and the general public. There is no spotted lanternfly quarantine for businesses or homeowners in Maryland at this time.
If you suspect you have found a spotted lanternfly, snap a picture of it, collect it, put it in a plastic bag, freeze it, and report it to the Maryland Department of Agriculture at DontBug.MD@maryland.gov. Dead samples from any life stage can be sent to the Maryland Department of Agriculture’s Plant Protection and Weed Management Program at 50 Harry S. Truman Parkway, Annapolis, MD 21401.
For more information about the spotted lanternfly, please visit the Maryland Department of Agriculture’s website at mda.maryland.gov/spottedlanternfly.

They're in the NE corner of Cecil County and will likely spread. Saw quite a few dozen today bike riding in the Lehigh Valley about 7 - 10 miles north of the epicenter (Rolling Rock Stone near Landis Store, PA). Still very few near/on my property. There's a good sized hole in the distribution. But where they are, there are lots.
