Shopping For Christmas Trees?

by Ryan Parker and Brian Eshenaur

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!Christmas tree farm in winter

 

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.

Print this list and keep it in your vehicles!

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).

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.”

Traveling for the Holidays?

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).

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 (spottedlanternfly@dec.ny.gov) 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.

Please use your social media to share the website https://nysipm.cornell.edu/environment/invasive-species-exotic-pests/spotted-lanternfly/ with family, co-workers, acquaintances, and friends. YOU can be an important factor in reducing the spread of this destructive insect pest.

2018’s Best of NYS IPM

“None of us is as smart as all of us.” –Ken Blanchard

2018 has been quite the year and we have been busy blogging, tweeting, videoing, and Facebooking about it. Here’s a recap of some of our more popular 2018 offerings:

ThinkIPM – our catchall blog and a great way to keep a pulse on what’s happening in New York State IPM.

Our most popular blog post was actually a guest blog by Paul Hetzler, CCE St. Lawrence County, Move Over, Medusa: Pretty? Poisonous! in the Caterpillar Clan. We’re big fans of his writing and this post on a venomous caterpillar caught a lot of your attention as well. (photo credit: Wikimedia Commons)

 

Are you safe now?

Ticks in February?

Ticks in the cold was also a popular topic. And relevant to now! Check out these two blog posts, Ticks don’t care what month it is and Ticks and the freezing weather. Hopefully they both convince you to keep up your daily tick checks.

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.

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 Spotted Wing Drosophila blog has an obvious focus, but the post Spotted lanternfly found in two counties in NY captured the most views.

 

Biocontrol Bytes was begun at the end of 2018 and many of you have been enjoying the updates on the Creating habitat for beneficial insects project.

 

We saw a number of news reports about bed bugs in schools, so we wrote Bed bugs in schools aren’t going away in The ABCs of School and Childcare Pest Management blog. And you read it. We just wish the news reporters and commenters did too.

 

The 2017 NEWA Survey: IPM impact includes such gems as “93% agreed or strongly agreed that NEWA pest forecast information enhances IPM decision-making for their crops”.

 

Gypsy moths on Christmas trees? Check out the Tree Integrated Pest Management blog and see how it’s now a thing in the Gypsy Moth Caterpillars -Scout for them now post.

 

Facebook

When it comes to Facebook, video rules. Our most popular Facebook post was our claymation video, Life Cycle of the Blacklegged Tick (and Lyme Disease Prevention!). And, by the way, this claymation was part of a large Don’t Get Ticked NY campaign launched in 2018!

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.

 

Twitter

We’re not surprised that our most popular Tweet of 2018 was about spotted lanternfly. Follow us on Twitter to keep up with the latest information.

 

 

 

Annual Report

This might be cheating, because it was just released and we have no data to show its popularity, but our 2017-2018 annual report is a 2019 calendar and everyone we have shown it to has been pretty excited.

Here’s a picture of the spotted lanternfly you have been hearing about.

 

 

 

 

 

 

 

So, as we raise our glasses to 2018 and look forward to 2019, include keeping up with NYS IPM Program amongst your resolutions.

Happy New Year!

Spotted Lanternfly Enters New York State

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

Red is ever a reminder to other critters: this might be toxic. (Photo Penn State)

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 spottedlanternfly@dec.ny.gov.

The Invasive of the Month Is … (Drum Roll)

Drum Roll: The Spotted Lanternfly

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.

Wait … now for the late breaking news:

Lanternflies Eat Everything in Sight. The U.S. Is Looking Delicious …
