The mission of the New York Invasive Species Awareness Week (ISAW) is to promote knowledge and understanding of invasive species and the harm they can cause by engaging citizens in a wide range of activities across the state, and empowering them to take action to help stop the spread.
While we won’t be able to gather for invasive species identification walks, removal projects, or in-person presentations, there are plenty of online opportunities to increase awareness. And the good news is that you will have access to statewide opportunities. Presentation topics run from learning how to identify plants information and enter it into iMapInvasives to the more specific info on beech leaf disease, crayfish, “murder hornets”, how climate change, and deer, impact native plants and pave the way for invasives, and more. For a full list of virtual events, visit https://nyisaw.org/events/.
And there are numerous challenges offered this year. Be sure to use the hashtag #NYISAW! ISAW Social Media Challenges, many suited for the kids, include:
Sunday – learn about your local invasive species and share a selfie
Monday – create some Invasive Species Art!
Tuesday – use the Agents of Discovery app to learn about invasive species
Wednesday – increase others’ awareness by creating a banner and hanging it in your window
Thursday – help track invasive species in NYS through iMapInvasives. New to iMap? There will be an online training at 1:00
So download the Seek app, head to the backyard and identify some invasive species. Upload the information to iMapInvasives. And then feel free to remove them. This weekend I’ll be CAREFULLY digging up wild parsnip along my roadside. How about you?

By now many Americans reading or watching the news have heard about “murder hornets” from Asia invading the American landscape. It is true that in many parts of East Asia, Japan in particular, a large hornet lives and feasts upon honey bees and other insects. This is the Asian giant hornet (AGH), or Vespa mandarinia, which is a relative of the European hornet (Vespa crabro) that we typically see in North America. The European hornet is an import to America that has naturalized, or become established here as if it was native. The Asian giant hornet has just arrived on North America’s west coast, by unknown means. Residents and beekeepers alike are hoping it doesn’t become naturalized in America.

The Asian giant hornet is the world’s largest, measuring 1.6 to 2 inches long, with a particularly large yellow-orange head. It is a social insect, living in colonies built in soil burrows dug by rodents and other animals. While people may not often see Asian giant hornets, beekeepers will definitely notice their decimated colonies of honey bees. It takes a handful of Asian giant hornets to slaughter an entire honey bee colony, after which hornets feed on the larvae, pupae and honey inside the hive. Japanese honey bees, which are a different species of honey bee than what we raise in North America, can fight back against AGH by surrounding and super-heating the wasp in a ball of bee bodies. Our European honey bees do not have this defense behavior. If AGH becomes established in the US and Canada, the greatest threat will be to beekeepers and their honey bees.
The hazard to humans posed by the stings of AGH is real. The venom is toxic and with their long stingers, AGH can inject more venom into a wound than most other stinging insects. Stings lead to intense pain and swelling, and can induce renal failure and anaphylaxis. Multiple stings can be deadly. But, these hornets do not come after humans and left alone, they mind their own business. The efforts to eradicate AGH from Washington State and Canada will be a priority aimed at avoiding their permanent establishment in the US. Unlike claims in some media outlets, it will likely take many years for this wasp to spread across the country on its own if we fail to eradicate it. Beekeepers will be on the front lines of detection.
*** 2020 UPDATE – A dead queen Asian giant hornet was discovered this spring on a road near Custer, WA, which is close to the western Canada border. This indicates that queens produced by at least one colony in the Fall of 2019 overwintered and emerged. To date (6/3/20) no other detections have been reported.
There are several species of wasps in the US that are very commonly confused with AGH:
Cicada Killer – Sphecius speciosus – a large, native, solitary wasp, does not readily sting or act aggressive toward humans, hunts cicadas, exclusively, digs burrows in the soil where eggs are laid upon the body of paralyzed cicadas. Common in suburban areas.

EuropeanHornet – Vespa crabro – an introduced social species, colonies started by a single queen, colony builds and expands a tan paper ball nest typically in hollow trees and abandoned barns and structures. More common in rural areas. Not aggressive unless harassed.

Baldfacedhornet – Dolichovespula maculata – Large black-and-white wasp, not a true hornet, colonies started by a single queen, nest is a grey paper ball usually high in trees or on the side of structures. Not aggressive unless harassed.

Yellowjackets (many species) – Vespula sp. – Small yellow-and-black wasps that nest in large colonies in soil and other man-made cavities. Can be aggressive, especially in early fall.

Paperwasps – Polistes sp. – Slightly longer than yellowjackets, various colors, long legs, umbrella comb nest with a few to a few dozen wasps. Not aggressive unless harassed.

The Bottom Line: A few Asian giant hornets were discovered in Washington State in 2019. The greatest threat is to honey bees and beekeepers. Efforts to eradicate this wasp are underway. New York does not have Asian giant wasps and hopefully won’t anytime soon.
Residents of the west coast should keep an eye out for Asian giant hornets and residents of Washington State are strongly encouraged to submit reports of sightings to the Washington State Department of Agriculture. If you live in New York and have questions about wasps or any stinging insects, you can contact NYSIPM or your local Cornell Cooperative Extension office for advice or to submit samples for identification.

“None of us is as smart as all of us.” –Ken Blanchard
Each year, NYS IPM staff are busy blogging about relevant topics. Here’s a recap of some of our more popular 2019 offerings:
ThinkIPM is our catchall blog and a great way to keep a pulse on what’s happening in New York State IPM.
No one wants to find an embedded tick.
We have spent a lot of time in the past year talking about how to prevent tick bites, from dressing in long pants, using repellents, and conducting daily tick checks. But sometimes one gets past you and you discover that new lump behind your knee has legs. There are always question about what to do next, and Help! I found a tick on me! was the most popular 2019 blog post.

Spotted lanternfly was also on your mind, and Traveling for the Holidays? provided a checklist for those traveling within the spotted lanternfly quarantine zone. Trust us when we say that you do not want to unintentionally transport Spotted Lanternfly egg masses in New York state.
Other IPM Blogs – Besides ThinkIPM, we have more dedicated blogs, and you don’t need to be a specialist to subscribe to them. Here are some of the more popular posts:
The most popular Biocontrol Bytes offering was a guest post from our collegues in the Cornell’s School of Integrative Plant Science, section of Plant Pathology and Plant-Microbe Biology, Anna Wallis, Kerik Cox, and Mei-Wah Cho. They discussed moving beyond antibiotics to the use of biopesticides in the post, Battling Fire Blight with Biologicals.
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!

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 (firstname.lastname@example.org) 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.

Do you go outside? Then the NY Natural Heritage Program is looking for you to help map invasive species! And they are providing free training throughout the state for your convenience. And it is easier than ever to contribute to this recordkeeping effort – iMapInvasives is available on your smartphone. (And recordkeeping is such an important step in IPM!)
New York iMapInvasives is New York State’s on-line all-taxa invasive species database and mapping tool. It’s one stop shopping to provide information on your invasive species observations and surveys in NY and control efforts. You can even use your smartphone to report new findings (a new feature for those that have already received training).
Citizen scientists, educators, and natural resource professionals are part of New York’s invasive species early detection network. Join them by learning how to use iMapInvasives. Visit www.nyimapinvasives.org for schedule details and registration.
With all the talk about climate change you might wonder how it will affect food production, pests, and even landscapes—and what you can do about it. From the Valentine’s Day massacre winter freeze to plant life gasping for water, changing weather patterns have affected our crops all over the Northeast. Learn how gathering information on weather and climate can help growers, gardeners and landscapers plan for changes. Find details on The Climate and Weather Conference webpage.
Remember the adage “knee high by the 4th of July”? This year it was ankle high. And dry.
Climate, Weather, Data: Protecting Our Crops and Landscapes. It’s all happening August 15, 2016 at the Albany County Cornell Cooperative Extension Office, 24 Martin Rd., Voorheesville, NY, 12186.
We’re honored that Richard Ball, the Commissioner of the New York State Department of Agriculture and Markets, will kick off the conference. Speakers from New York and across the Northeast will discuss the current state of knowledge on climate change and changes in weather patterns. We’ll also learn how collecting climate and weather data can help us predict and manage pests. Open discussion sessions are included so you can ask your own questions. Join us.
It’s the 3rd Invasive Species Awareness Week (ISAW) in New York. Groups statewide have sponsored activities July 10 – 16. We invite you to join in and learn how to protect your favorite natural areas.
What’s at stake? Some of the greatest harm both to our environment and agriculture is caused by invasive plants and animals — organisms that have been introduced to new areas, whether accidentally or intentionally, then spread uncontrollably.
Last year, PRISM organized more than 100 invasive species activities were held statewide. This year, the regional New York PRISMs (Partnership for Regional Invasive Species Management) are poised and ready with a lineup of even more great activities and events to mark the occasion. Invasive Species Awareness Week offers many opportunities to learn more about invasives — including how prevent and manage their spread.
Japanese barberry is one example of a common landscape plant that has escaped cultivation and invaded natural areas.
What makes a species invasive? Most reproduce in high numbers, lack predators and are highly adapted to their new environment. They can be costly, affect your health or vastly change ecosystems. Examples? Emerald ash borer, giant hogweed, and Japanese stiltgrass — to name but a few.
Invasive species removal events are scheduled throughout the state this week. Photo: Joellen Lampman
Invasive species are often spread unknowingly. A gardeners’ plant swap, dumping a bait bucket, moving firewood to a campsite miles away — it can be as simple as that.
You can help manage and control invasive species; in fact, people like you are often the first line of defense in reporting new infestations. How? By:
keeping a sharp eye out for unwanted hitchhikers in the plant and animal kingdoms
learning about which invasive species are of local concern by visiting your local PRISM website
Stop the invasion. Protect New York from invasive species: that’s our state’s slogan. The line-up of events across New York includes an array of activities such as removing invasive species, screenings of “The Hemlock Woolly Adelgid” documentary, and invasive species workshops. The full schedule of events is online at http://www.nyis.info/blog/events/. Events are free, but preregistration for some events may be requested.

by Mary M. Woodsen Comments Off on For New Invasive Lanternfly, Best IPM Tool is Your Eyes
Spotted lanternfly, aka Lycorma delicatula — put it on your radar now. True, as far as we know it’s not in New York. Yet. And with winter blowing in, any likelihood of seeing it this year is grows smaller by the day. But considering the havoc this new invasive could wreak if it breaks through the quarantine in Berks County, Pennsylvania, this is one pest to remember. And — especially if you’ve been in southeastern Pennsylvania of late — you can take action now.
Yes, it’s pretty. Pretty bad. Though it’s probably not in NY yet, scout now for egg masses; next year for nymphs and adults. Photo credit: L. Barringer, PA Dept of Agriculture.
This pest lays egg masses — beginning in September and up till the onset of winter — on just about anything with a smooth surface. So check your truck or camper, or any smooth-surfaced outdoor furniture or equipment you picked up during your travels. Here’s what to look for: a grey, puttylike, waxy coating over a mass of seedlike eggs that look as if they’re trying to poke through it.
What’s at risk? Apples. Grapes. Peaches. Dogwoods. Lilacs. All told, this natty but nasty critter (adults and nymphs alike are handsome little devils) hammers 70-plus species of smooth-barked trees and shrubs — plants we rely on for everything from apple pie and fine wine to the beauty they bring our yards and landscapes. And right now, our eyes are the best IPM tool we have for keeping this pest at bay.

Actually, spotted lanternfly isn’t a fly. Not even a moth, though with wings spread it sure looks like one. It’s what entomologists call a “true bug” — an insect that pierces a plant with specially adapted mouthparts that suck up sap, rather as we might drink soda with a straw. But that sap is a plant’s lifeblood. Get enough sap-sucking bugs on your grapevines or cherry trees, and you’ve got a problem on your hands.
True, lanternfly gets around by hopping and seems not to move quickly on its own, despite the adults’ pretty wings. Problem is, this adaptable pest can hitchhike unseen on just about anything — not just on trucks cars and campers but flowerpots or outdoor furniture. Suddenly, Berks County doesn’t seem so far away.
New York’s orchards and vineyards alone contribute about $330 million to the state’s economy. When you factor in the value fine wines and grape juice, peaches and cherries, landscape and forest trees and shrubs, it looks lots worse. So of course we’ll remind you about spotted lanternfly next spring.
If you think you found egg masses, take a photo, scrape some off, place your sample in alcohol or hand sanitizer in a leak proof container and report to the New York State Department of Agriculture and Markets, Division of Plant Industry at 518-457-2087 or via email at email@example.com. Think you’ve seen the bug itself? Do the same photo-hand sanitizer-report-it thing. Now.
