The NYSIPM program, along with the Department of Agriculture and Markets, and the Department of Environmental Conservation have been monitoring for Spotted Lanternfly since its first occurrence in PA in 2014. In preparation, we developed educational resources for New Yorkers. Partnering with affected states, we’ve maintained a map tracking its spread and quarantines across the mid-Atlantic and Northeast region.

Now, as of August 14, 2020 has confirmed a living population of spotted lanternfly on Staten Island. Because pests don’t care about borders, experts anticipated this introduction into the state and put in place the groundwork needed to keep ahead of this invasive. Continue Reading →

by Debra E. Marvin Comments Off on Our 2018-2019 Annual Report – Nematodes, Spotted Lanternfly… a last Look and Recap
Today we reach the end of our in-depth look at our most recent annual report from the New York State Integrated Pest Management Program. While many of you receive it in the mail, the large number of in-person sharing we generally do as we speak with people around the state was obviously limited. We continue to do our best to reduce risk from pests and treatments, and to reduce the risk of Covid-19.
WE LOOK FORWARD TO A RETURN TO THE MANY WORKSHOPS, PRESENTATIONS, ON-SITE EVALUATIONS and GATHERINGS THAT WE VALUE AS PART OF OUR FOCUS!

Nematodes Go to School
For decades, researchers and practitioners alike have played around with beneficial nematodes to control insect pests in turf and agricultural crops. These nematodes are microscopic worms that move through soil looking for host insects to infect. Once inside a grub or other insect, the nematode releases bacteria that feed and reproduce, eventually releasing a toxin that kills the host. As an added bonus, nematodes often persist for years in the soil after just one application—they’ve been shown to permanently establish in both alfalfa and corn. Nematodes are an ideal biological control agent because they occur naturally in soil and can be applied to boost pest control. Now these tiny but mighty native worms have been enlisted to help protect school playing fields from pests, and to help teach science, too. Dr. Kyle Wickings, a Cornell entomologist, has been using native New York beneficial nematodes on school playing fields to target grubs, and to reduce the need for pesticide sprays. NYSIPM staff teamed up with him to train teachers in four school districts to add nematode sampling to their science curriculums. In addition to student-collected data, the team inoculated eight playing fields at three schools and then sampled the fields in the fall for signs that the little worms were sticking around. To date, results have been too variable to make recommendations, but our researchers—as tenacious as these worms—will keep on testing.
(Above) Students learned that these beneficial nematodes (round worms) might be hard to see without a microscope, but are hard at work attacking grubs in the soil under the playing fields. David Chinery, Horticulture and Turf Educator at CCE Rensselaer County, helps this middle school teacher get her hands dirty.
Here, during our Nematodes in the Classroom Workshop, she sifts through soil for dead wax worms that indicate whether nematodes are present and successfully parasitizing insects.
The Spotted Lanternfly: They Get Around
Hailing from Asia, the spotted lanternfly (SLF) arrived in Pennsylvania in 2012 on landscaping stone. They’ve been ravaging vineyards and making a mess of backyards ever since. SLF are clumsy fliers but adept hitchhikers. They lay their eggs on practically any hard surface—wood, rusty metal, railroad cars, and shipping containers are all fair game. SLF has been called, “the worst invasive we’ve seen in 100 years.” Of their arrival here, New Yorkers now say, “It’s not a question of if, but when.” A bright spot is the incident command structure formed by New York’s Departments of Environmental Conservation, Agriculture and Markets, and Parks. They started preparing early, and asked NYSIPM to help with outreach and awareness. Our goal? Immediate identification and education to prevent SLF establishment for as long as possible. Delaying their imminent debut gives us more time to inform the public, while allowing researchers to expand the management toolkit—including the use of natural enemies. We’ve created pest alerts, online courses, identification guides, YouTube videos, slide sets, and webinars. NYSIPM talks about SLF a lot. In the first year our staff mentioned SLF in more than 60 presentations, alerting nearly 2,500 participants representing the grape, wine, apple, hops, ornamentals, vegetable, berry, turf, and landscape industries. The good news? The efforts seem to be working. At the time of printing, a few SLF have been sighted in New York, but no infestations found. We want to give a shout-out to our friends in Pennsylvania who have generously shared information, and to New York’s government agencies and extension educators for getting the word out.
(Above) Dressed to kill. These beautiful yet destructive adult spotted lanternfly adults are out and about in the late summer and fall. Watch for them, but also for egg masses and nymphs the rest of the year.
In closing, our annual report is an important part of our program because it showcases our service to our stakeholders and justifies the trust of our collaborators and funders. Highlighting many, but not all, of our accomplishments takes time. Collecting the stories and photos–after narrowing down the list of ideas–and then writing concise and interesting stories is the work of our director and commodity directors. After the retirement of our lead staff writer, Science Writer Mary Woodsen, we want to thank Mariah C. Mottley for her contribution!

by Debra E. Marvin Comments Off on Shopping For Christmas Trees?
When choosing the perfect tree, people usually consider variety, size, and shape. But with the phenomenon of a new invasive planthopper, Spotted Lanternfly (Lycorma delicatula) (SLF), the tree’s origin may be something to think about.
We always suggest fresh-cut trees from New York’s many great tree farms!
First of all, we’ll say it’s unlikely that SLF will be on your cut tree. Conifers are not a food source for this pest, but egg-laying females are indiscriminate as to where eggs are placed. That’s why we offer a list for travelers making their way through quarantined areas.

At this time of year, winter has killed off adults, but their hardy egg masses remain. Although ornamental in appearance, Spotted Lanternfly is one “ornament” you don’t want hatching from their mud-like egg masses and decorating your property this coming spring. SLF causes economic damage to agriculture, forestry and tourism, and is a major nuisance to homeowners. Learn more by visiting our SLF website!
We bring this up because the SLF quarantined areas of Pennsylvania (shown in blue on the map below) happen to be home to many Christmas tree farms (Berks, Bucks, Carbon, Chester, Dauphin, Delaware, Lancaster, Lebanon, Lehigh, Monroe, Montgomery, Northampton, Philadelphia, and Schuylkill).
Distribution map as of November 2019
If you’re buying a pre-cut Christmas tree, ask the seller where their trees came from. If it’s from PA, learn about this pest and inspect the trunk. But don’t stop there. Get into the habit of citizen science! “Scouting” (actively knowing how, why, and where to look) for pests gives you a critical role in stopping the spread.

What else can you do?
There are plenty of cut-your-own farms in New York with family-friendly atmosphere where you can get a fresh tree. If you don’t have time for a cut-your-own experience, ask your tree sellers if they’re aware of SLF risk on out-of-state trees. Awareness is key!
Here’s some Christmas Tree tips from our own Christmas Tree expert, IPM’s Brian C. Eschenaur:
2019 was an excellent growing season for Christmas Trees. We had more moderate summer temperatures and good rainfall this year. Those suitable growing conditions allowed trees to put on healthy new growth, and the fine weather gave Christmas tree growers good conditions to prune trees so they will be in great shape for harvest. This year’s early-November cold snap was also beneficial in “setting” the needles which is good for longer needle retention in some tree species.
Once in a while we hear from people concerned about the “single use” aspect of real Christmas trees. But considering the alternative of a plastic tree produced, then shipped from overseas, (and eventually ending up in a landfill), real trees have their benefits. They are a renewable resource and by buying locally you are supporting growers that will continue to maintain their fields which are part of the greenspace we all value.
Choose a variety and shape that fits your needs. Many growers are producing a wide variety of firs, spruces and even old-fashioned pines. Each variety tree offers its own shape, color, fragrance, and even branch stiffness which is important to consider for holding ornaments.
Trees always look smaller in the field so don’t forget the tape measure. Measure the floor to ceiling height before you go tree shopping and then while choosing so you end up with a tree that fits nicely into your home.
Don’t be afraid to bend the branches and shoots. Green needles should not come off in your hands. Also, the shoots should be flexible. Avoid a tree if the needles are shed or if the shoots break instead of flexing.
If possible, make a fresh cut on the bottom so the tree’s vascular tissue (pipe work) is not plugged and the tree can easily take up water. Then, if you’re not bringing it into the house right away, get the tree in a bucket of water outside.
Once you move your tree inside the house, don’t locate it next to a radiator, furnace vent or other heat source. And always remember to keep water in the tree stand topped off, so it never goes below the bottom of the trunk.
Whatever you choose to do, enjoy your “Holly Jolly Christmas” and hopefully “it’s the best time of the year.”

Cheers from all of the NYSIPM staff.

Be aware that Spotted Lanternfly could travel back with you!
Are you visiting the Spotted Lanternfly (Lycorma delicatula) quarantine zones within certain counties in Delaware, Maryland, New Jersey, Pennsylvania, or Virginia?
If yes, beware! Citizens like you may unintentionally transport Spotted Lanternfly egg masses. While adult activity slows or stops this time of year, egg masses that were deposited on transportable items are a major part of this pest’s hitchhiking ways.
NYSIPM has made a checklist of common items that harbor egg masses (see below).
Check these items to ensure you are not bringing SLF with you out of the quarantined areas!

by Debra E. Marvin Comments Off on Have You Spotted Our New SLF Webpage?
Here’s the latest on Spotted Lanternfly from Ryan Parker, Extension Aide at NYSIPM.

Concern over the invasive and destructive spotted lanternfly (Lycorma delicatula) (SLF) generated many online resources by states researching new and active populations. Thought to have arrived in Berks County, PA, in 2012, this showy planthopper attacks more than seventy species of plants in the United States. New York State’s primary concern is outreach, monitoring, and proactively approving 2ee pesticide labels for control. Because live adults and nymphs (and egg masses) hitchhike from states with known populations, New York State has an external quarantine.
An external quarantine is a restriction of specific items that facilitate ‘hitchhiking’. In other words, if you’re traveling back from a state with an established population consider that your utility trailer, bicycle, tent canopy, or that swing set you bought in a yard sale might have SLF adults, nymphs, and egg masses tagging along. Any item that has been outside for a while needs to be checked before it crosses the border. Here’s the full list, downloadable, printable.
Download, print and share to reduce the spread of Spotted Lanternfly
In an attempt to educate the public and limit the spread of this pest, New York State Integrated Pest Management (NYSIPM) has teamed up with New York State Department of Environmental Conservation (NYSDEC), United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS), and New York State Agriculture and Markets (NYSDAM) to create the New York State Spotted Lanternfly Incident Command System (NYS SLF ICS).
Currently, NYSIPM’s primary SLF focus is outreach. We’ve created materials that help identify, monitor, and manage this pest. Along with the public departments listed above, we continue to remind NY residents how to report findings (email@example.com) and we provide educational materials LIKE OUR NEW WEBPAGE. Besides our many resources (Powerpoint presentations, Spark videos, posters, photos and much more), and links to other state or government agency information, you’ll find a regularly updated incidence map showing county-by-county news of SLF sightings and populations across the Northeast and mid-Atlantic regions.
Coming soon, two Moodle courses from NYSIPM and our Cornell CALS collaborators. One course provides general knowledge about SLF, while the other focuses on Tree of Heaven (Alianthus altissima), one of SLF’s preferred hosts. Both offer pesticide applicator credits.
While visiting our blog, you have also been checking out older posts. Our second most popular post viewed in 2018 was a 2014 post, Identifying Your Pest – with Poop?. There are a lot of budding scatologists out there.

Our new Spotted Lanternfly video, Have YOU Spotted Lanternfly Egg Masses was just posted, but it has already reached the number two spot. This invasive insect is getting a lot of attention and we need your help to keep track of it in New York.
It’s unfortunate that we must spread the news that living Spotted Lanternflies have been detected in New York State, but to be forewarned is to be forearmed. Here is the text of the press release published by the New York Department of Environmental Conservation and the Department of Agriculture and Markets:
DEC and DAM Announce Confirmed Finding of Spotted Lanternfly in Albany and Yates Counties
State Agencies Encourage Public to Report Findings of Invasive Pest

The New York State Departments of Environmental Conservation (DEC) and Agriculture and Markets (DAM) today confirmed that spotted lanternfly (SLF), an invasive pest from Asia, has been found in Albany and Yates counties. A single adult insect was discovered in a vehicle in the Capital District. In addition, a single adult insect was reported on a private Keuka Lake property in Penn Yan, Yates County.
“DEC and our partners at the Department of Agriculture and Markets are closely tracking the spotted lanternfly, a destructive invasive pest, as part of our ongoing efforts to prevent its establishment and spread in New York. This pest has the potential to severely impact our state’s agricultural and tourism industries,” DEC Commissioner Basil Seggos said. “We are encouraging the public to send us information to bolster our efforts—they are our eyes on the ground.”
Following both reported cases, DEC and DAM immediately began extensive surveys throughout the area. At this time, no additional insects have been found. DEC and DAM urge New Yorkers to report potential sightings to firstname.lastname@example.org.
Southeastern Pennsylvania, the epicenter of spotted lanternfly’s arrival in 2014, might seem far enough away to give us in New York prep time for dealing with this new pest, a weak flyer that usually hops to get around. But with the spotted lanternfly (Lycorma delicatula—and SLF for short), all bets are off. After all, it took over Korea, whose climate is surprisingly like our own, in no time flat. And now it’s in Maryland. Delaware. Virginia. New Jersey.
New York’s first find happened to be dead. Blind dumb luck.
A bit creepy, how cool it looks. (Photo insectimages)
How anything so pretty could be so nasty boggles the mind. But it’s the nature of nature. Since ID’ing SLF correctly is key to good IPM, let’s start with the nymphs—the young-uns. In this case they come in two snazzy colors. The early-stage nymphs are straight-on black or, once they’ve molted, black and white—handsome devils or trendy fashionistas; take your pick. For late-stage nymphs (late-stage means they molted—again—and outgrew the skin they had after they hatched), add blobs of blood-red, and that critter looks ready to conquer the world.
Which it might.
Does that bright, traffic-light red signal toxicity, as it does for many other potential prey? Right now all I know is that birds have been seen throwing up after grabbing one for a snack—and yes, they are toxic to us.
Red is ever a reminder to other critters: this might be toxic. (Photo Penn State)
Meanwhile, adult SLFs look positively benign. Lovely, in fact. Don’t believe it for a minute. These classy lads and lassies resemble butterflies or moths, but don’t believe that either—they are, you’ll recall, planthoppers; the name refers to its mode of locomotion.
Whatever. Spotted lanternflies have a destiny. Their natural expertise in the pole-vault isn’t their only way to get around. How many roads (think interstates especially) wend their way from southeastern Pennsylvania to points north, south, east and west? Lots.
Consider your car or camper, for starters. Firewood? You’d be slack-jawed at the degree to which firewood fits into the equation. Just the eggs alone—not easy to see with a cursory look—can easily hitch rides to new areas, meaning that New York is a mere hop, skip and a jump away. Trains, tractor trailers, wheel wells, the cargo hold in a jet—this pest doesn’t need to lay its eggs on organic matter. Planning a long-distance road trip? California, here we come.
“I don’t want to scare people,” says Dr. Surendra Dara, an IPM and crop advisor at the University of California, “but it has the potential to spread, and we do not have a biological-control agent.”
Which is why you, dear reader, are our eyes on the ground.
But wait. Other than toxicity, I haven’t even told you why to be alarmed about this critter. Grapes, apples, hops—these and more high-value crops rank in the billions for New York. Apples alone ring the register at about $317 million.
New York’s forestry crops are vital, too. Here’s what forest crops provide:
jobs for 49,200 people with payrolls of over $1.6 billion;
manufacturing, recreation and tourism providing over $11.0 billion to our economy;
removing greenhouse gases from the atmosphere, sequestering carbon, and producing oxygen critical for all life on earth;
filtering and buffering clean drinking water for millions of New Yorkers.
As our eyes on the ground, here’s what you need to know. Signs that spotted lanternfly are at our collective doorstep include:
sap oozing or weeping from tiny open wounds on tree trunks;
a yeasty smell (been near a brewery lately? That’s it);
inch-long, brownish-gray egg masses—like waxy mud when new, brown and scaly when old
heaps of honeydew under trees and vines and covered, often as not, with black sooty mold.
When you see this many SPFs in your orchard (this is Pennsylvania, mind you) — watch out. (Photo Smyers, Penn State)
Besides fruit and hops, what’s at risk? Everything from willows to walnuts—and smooth-barked trees especially. But keep in mind that many a mature tree which, once it has packed on the pounds around its waist and takes on a decidedly rough or furrowed look, looks svelte and clean-cut while still relatively young. Go outside and look at any gently-furrowed tree, and chances are you’re looking at a host. For those areas where tree-of-heaven runs rife, well—you’re looking at what might be its most favorite host of all.
Though it’s hard to wrap your mind around, it sups on some—maybe all—field crops. “We’ve seen it in some of the grain crops that are out there, soybean and what have you,” said Fred R. Strathmeyer Jr., Pennsylvania’s deputy secretary of agriculture. “It’s able to feed on many, many different things.”
Now think about honeydew. Not the drink, not the melon; rather the stuff bugs secrete as they feed. A case of in one end, out the other as they move down the chow line. Although native insects also secrete honeydew, the size of the SLF and staggering numbers that congregate from place to place makes for a remarkable amount of honeydew. Parked your car beneath an infested tree? Time to clean off those sticky windshield wipers.
For sure—this sticky mess and the swarms of insects it attracts gets in the way of outdoor fun. In Pennsylvania, where SLF populations are the densest, people near the heart of the problem can’t go outside without getting honeydew on their hair, clothes, and whatever they’re carrying. At which point “outdoor” and “fun” no longer have all that much in common.
So that’s it in a nutshell and, for spotted lanternfly, all the news that’s fit to print. For now.
