Ticks and Their Pathogens in New York State– New Findings Released

A scientific paper, Active surveillance of pathogens from ticks collected in New York State suburban parks and schoolyards (2017-2018), was published in July of 2020. Four NYSIPM Staff– Dr. Jody Gangloff-Kaufmann, Joellen Lampman, Dr. Elizabeth Lamb, and Dr. Matt Frye are among the authors. The increasing number of cases of tick-borne disease prompted this work, and its success will help identify their risks to New Yorkers’ health and the health of their pets and livestock.

Why? The goal of this study was to highlight the importance of active surveillance for tick-borne pathogens, by describing their prevalence in ticks collected from school yards and suburban parks, and to guide the use of integrated pest management in these settings.

Study sites included 32 parks and the grounds of 19 schools on Long Island, in the lower Hudson Valley, and in the NY’s Capital Region. Ticks were collected from the environment using white flannel tick drag cloths, either using a transect protocol for school grounds or a presence-absence scheme in parks.

Collected ticks were primarily Ixodes scapularis (blacklegged tick), plus: the newly invasive Haemaphysalis longincornis (Asian longhorned tick), Ixodes dentatus, and Dermacentor variabilis (dog tick).

Blacklegged ticks are the smallest ticks that feed on people. The poppy seed sized nymph is considered the most dangerous.

Ticks were then sent on to the Cornell Animal Health Diagnostic Center for analysis of pathogen presence, with details such as collection site, time of day and weather conditions, life stage.

Experts tested all I. scapularis for the presence of 17 different pathogens. Diseases found in the ticks collectedin 2017-2018 included:  Borrelia burgdorferi (Lyme disease), Anaplasma phagocytophilum (anaplasmosis), Babesia microti (Babesiosis), Borrelia miyamotoi, Powassan virus, Heartland virus, Rickettsia, and SFTSV.  In some cases, a tick carried two or three pathogens.

What does this mean for you?

-Ticks are commonly found where athletic fields border woodlots. Schools should monitor their grounds for ticks and consult with extension services to understand the risks.

-Encourage school officials to contact the New York State Integrated Pest Management Program for help developing a plan to manage tick risks while minimizing impact on the health of people and the environment.

-Understand that social distancing while hiking may push you towards the edges of even wide, flat trails, so you may brush up against vegetation with ticks–It’s important for park and wildlife preserve visitors take protective measures.

-Help increase awareness across all residential areas, public spaces, and rural areas of the Northeast.

-The distribution of Powassan virus on Long Island is broader than previously documented. Powassan virus can be transmitted after just minutes of attachment.

-Preventative measures including frequent tick checks and permethrin-treated clothing are important year-round to prevent tick bites.

-Dogs, cats, and horses are susceptible to tick-borne diseases and should be monitored and treated in consultation with your veterinarian.

Note: This surveillance study captured the first sample of the invasive Asian longhorned tick species, Haemaphysalis longicornis, in NY.

SPOTTED LANTERNFLY HAS OFFICIALLY ARRIVED IN NYS: Here’s what you should know..

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.

Knowledge and experience from Pennsylvania’s spotted lanternfly specialists continues to benefit Cornell extension and research staff. Pennsylvania agriculture experienced grapevine deaths in some vineyards, and their economists estimate a potential combined annual loss to their state of $324 million and 1,665 jobs. Because of SLF’s ability to be a significant agricultural pest, research is underway even now, as Cornell researches biological and other control options.

photo of adult lanternfly and egg masses on tree bark

The spotted lanternfly is not a fly, but a large planthopper. Adults are about an inch long. They do not bite or sting, and are not a threat to people, pets or livestock. For most New Yorkers, it will be no more than a nuisance pest. Nymphal and adult spotted lanternflies have piercing-sucking mouthparts that drill into plant phloem. SLF’s excrement—a sappy liquid called honeydew—makes things sticky and becomes the breeding ground for sooty mold, an annoying black fungal growth that is not toxic and does not kill plants. If necessary, wash honeydew and sooty mold off of your outdoor belongings, and move them out from under trees that have hosted the SLF. Note: honeydew can also draw ants and yellow jacket wasps.

Spotted lanternfly’s favorite host is another invasive species, the Tree of Heaven, but they also feed on many other trees and plants (see our list). Unfortunately, this includes cultivated grapevine. With New York state’s important wine production and grape growing regions from Long Island to Western NY, we are particularly concerned about this pest’s impact.

To properly identify spotted lanternfly and understand its life cycle, host plants, and how to monitor and manage it, visit our resources here.

“What should I do?”

1) If you think you see a spotted lanternfly, use the new reporting form found here: https://survey123.arcgis.com/share/a08d60f6522043f5bd04229e00acdd63

2) Educate yourself. It is likely that spotted lanternfly will continue to spread north through New York and New England. Check out the lanternfly life cycle  here so you’ll know what to look for. From fall through spring, look for egg masses. (See: how to destroy egg masses). In late spring and early summer look for the nymph stages; in late summer through fall, look for adults.

life cycle graphic

3) Don’t transport this pest. Individual and commercial travelers alike should be aware that there’s the potential to spread this insect to new areas without knowing it.  Adult spotted lanternfly can end up in vehicles. Egg masses can be laid on virtually anything, and can be overlooked. Inspect anything that you load into your vehicle. Checklist here: https://nysipm.cornell.edu/sites/nysipm.cornell.edu/files/shared/documents/SLF-checklist.pdf

4) Keep up with the latest news on the spread of Spotted Lanternfly and other pest management concerns by following this and other NYSIPM program blogs, Facebook page, Twitter account and Instagram.

For Immediate Release:  August 14, 2020

State Agencies Encourage Public to Report Findings of Invasive Pest

The New York State Departments of Agriculture and Markets (AGM), Environmental Conservation (DEC), and Office of Parks, Recreation and Historic Preservation (OPRHP) today confirmed that Spotted Lanternfly (SLF), an invasive pest from Asia, has been found on Staten Island.  Several live, adult insects were discovered by OPRHP staff in Clay Pit Ponds State Park Preserve.  SLF (see photo below) is a destructive pest that feeds on more than 70 plant species, including tree-of-heaven, and plants and crops that are critical to New York’s agricultural economy, such as maple trees, apple trees, grapevine, and hops.

State Agriculture Commissioner Richard A. Ball said, “The Department is working closely with its partners at the Department of Environmental Conservation, the State Office of Parks, Recreation and Historic Preservation, and the U.S. Department of Agriculture (USDA) to mitigate the impacts of this destructive pest, which can weaken plants and have a devastating impact on agriculture.  While this find on Staten Island is concerning, New York State has taken strong actions to combat the establishment of SLF since 2017.  We will continue our work to survey and inspect high-risk areas and implement targeted management plans.  We also urge the public to be vigilant and report any suspected sightings of SLF to help slow the spread of this invasive.”

DEC Commissioner Basil Seggos said, “Since Spotted Lanternfly was first discovered in neighboring states, DEC has worked aggressively with the State Department of Agriculture and Markets, Office of Parks, Recreation and Historic Preservation, USDA and other partners to educate New Yorkers and take steps to prevent this invasive species from establishing itself in New York State. This invasive pest has the potential to severely impact and stress New York’s forests, agricultural crops, and tourism industries. The first live find on Staten Island is concerning, but our goal remains to find Spotted Lanternfly early and prevent it from further entering New York State and limiting any serious threats to our natural resources.”

State Parks Commissioner Erik Kulleseid said, “Spotted Lanternfly poses a troubling threat to the environment and agriculture of New York State but also to the quality of recreational opportunities and experiences we offer in our State Parks and public lands. I applaud our Parks’ environmental stewardship staff for identifying this pest, so New York State can quickly begin taking steps to slow its spread. Park visitors across the state can help in identifying and reporting this destructive pest, and I urge them to familiarize themselves with its signs.”

Following the finding by OPRHP, AGM, working with DEC, OPRHP, and the USDA, immediately began extensive surveys throughout the area.  Crews will continue to survey areas on Staten Island, develop management plans to slow SLF’s spread, and minimize the damage and impact from this invasive species.

AGM urges New Yorkers to report potential sightings using the web reporting tool found here: https://survey123.arcgis.com/share/a08d60f6522043f5bd04229e00acdd63

SLF feedings can stress plants, making them vulnerable to disease and attacks from other insects. SLF also excretes large amounts of sticky “honeydew,” which attracts sooty molds that interfere with plant photosynthesis, negatively affecting the growth and fruit yield of plants, and impacting forest health. SLF also has the potential to significantly hinder quality of life and recreational activities due to the honeydew and the swarms of insects it attracts.

First discovered in Pennsylvania in 2014, SLF has since been found in New Jersey, Maryland, Delaware, West Virginia and Virginia. Given the proximity to the Pennsylvania and New Jersey infestations, New York State is at high risk for infestation.

Since 2017, AGM, DEC, and OPRHP have taken an aggressive approach to keeping SLF from establishing in New York State, conducting surveys of high-risk areas across the State; inspecting nursery stock, stone shipments, and commercial transports from quarantine areas; and launching a comprehensive education and outreach campaign to enlist the public’s help in reporting SLF.

While these insects can jump and fly short distances, they spread primarily through human activity. SLF can lay their eggs on any number of surfaces, such as vehicles, stone, rusty metal, outdoor furniture, and firewood. Adult SLF can hitch rides in vehicles, on any outdoor item, or cling to clothing or hats, and be easily transported into and throughout New York.

The public is encouraged to thoroughly inspect vehicles, luggage and gear, and all outdoor items for egg masses and adult SLF before leaving areas with SLF, particularly in the counties of states in the quarantine area—Pennsylvania, New Jersey, Maryland, Delaware, West Virginia and Virginia.   If SLF adults are found, residents should remove them and scrape off all egg masses.

Residents can also help by allowing surveyors access to properties where SLF may be present.  Surveyors will be uniformed and will always provide identification.

Identifying SLF

Adult SLF are active from July to December. They are approximately one-inch long and half an inch wide at rest, with eye-catching wings. Adults begin laying eggs in September. Signs of an SLF infestation may include:

  • Sap oozing or weeping from open wounds on tree trunks, which appear wet and give off fermented odors.
  • One-inch-long egg masses that are brownish-gray, waxy and mud-like when new. Old egg masses are brown and scaly.
  • Massive honeydew build-up under plants, sometimes with black sooty mold developing.

People are Talking About Gypsy Moths

ADAPTED FROM A GREAT ONLINE RESOURCE!!  THE FOREST PEST HANDBOOK is a publication of the NYSIPM Program and New York State Department of Agriculture and Markets, authored by Elizabeth Lamb and Jennifer Stengle Lerner.

graphic is a screenshot of the cover of the FOREST PEST HANDBOOK showing a tree canopy.

People around the state are noticing gypsy moths…

Specifically European Gypsy moth — Lymantria dispar dispar

(Note: The Asian gypsy moth is a concern in some parts of the United States but is NOT currently an invasive pest in New York.)

The European gypsy moth was accidentally introduced into Massachusetts in l869. By 1902 this pest was widespread in the New England states, eastern New York, and regions of New Jersey.

Generally from late July through early September, female moths will lay egg masses on bark, firewood, exterior of campers and outdoor equipment and be easily transported. The gypsy moth is an important insect pest of forest and shade trees in the eastern United States. Heavy defoliation by the larval stage of this pest causes stress to infested host plants. Adult male moths are dark buff and fly readily during the day. Females are white with black, wavy markings, have robust abdomens, wingspans up to 2 in ches (50 mm) but do not fly.

Egg masses may be found on trees, rocks and other surfaces from early April through mid May. They are light tan, and the eggs inside are black and pellet like. Each mass may contain 400-600 eggs.

Gypsy moth egg cases. from the NYSIPM Flickr account.

The larval stage (caterpillar) is hairy, and a mature larva is 2-2.5 inches (50-65 mm) long with a yellow and black head. Behind the head on the thorax and abdomen are five pairs of blue spots (tubercles) followed by six pairs of brick red spots. Young larvae feed on foliage and remain on host plants night and day.  Around mid April, larvae emerge from egg masses. In late May, when about half-grown, larvae change their behavior and usually feed in the trees at night, and move down to seek shelter in bark crevices or other protected sites during the day. Larvae molt numerous times until full grown at 2-2.5 inches.  Larval feeding is THE STAGE WHEN TREE DAMAGE OCCURS. Feeding on leaves can last for up to six weeks. Look for defoliation of host trees. You may also hear frass dropping from trees (believe it or not…), though that may come from feeding by other species of caterpillars. Caterpillars may move down into bark crevices during daytime and return to canopy feed at night.

The pupal stage is dark reddish-brown and is held in place to some object by small strands of silk. Pupation is generally in July or early August. This year, adults have been seen in July.

Borrowing from our friends over at University of Illinois Extension.

Which tree species does this pest damage? PLENTY!

Alder (Alnus spp.) Aspen (Populus spp.) Gray birch (Betula populifolia) White birch (B. papyrifera) Hawthorn (Crateagus spp.) Larch (Larix spp.) Linden (Tilia spp.) Mountain ash (Sorbus spp.) Oaks (Quercus spp)Lombardy poplar (Populus nigra) Willows (Salix spp.) Witch-hazel (Hamamelis spp.) Beech (Fagus spp.) Red cedar (Juniperus spp.) Chestnut (Castanea spp.) Hemlock (Tsuga spp.) Plum (Prunus spp.) Pine (Pinus spp.)

What to do? The time to act is/was when egg masses can be found and destroyed  (fall, winter and spring), or when young larvae can be reduced in numbers. If you’ve seen a lot of adult moths, you might want to take a look for egg masses on your trees in the fall and winter.

5th Annual Invasive Species Mapping Challenge

iMapInvasives has put out a call for help and we’re happy to do our bit. Check out this citizen science project looking at increasing the amount of information regarding invasive species throughout New York. Written by Mitchell O’Neill, End User Support Specialist for iMapInvasives.

There is one more weekend in the 5th Annual Invasive Species Mapping Challenge – ending Wednesday July 15th! Join this citizen science effort to fill data gaps for four key invasive species in New York State’s official invasive species database, iMapInvasives. The species are jumping worm, tree-of-heaven, water chestnut, and European frogbit – which have wide-ranging impacts on land and water resources, agriculture, gardening, and recreation.

In this webinar, the iMapInvasive’s team cover the identification of these species and how you can participate.

 

Did we mention there are prizes for each species? Here is one example.

Great data has come in over the past 2 weeks, but it’s still very much anyone’s challenge! The top contributor for each of the four species wins a prize!

I encourage you to go out and search for invasives this weekend – remember to record not-detected records if you search for one of the species in its habitat but did not find it. View our webinar on identifying these species and reporting them to iMapInvasives here. Please email imapinvasives@dec.ny.gov with any questions!

Comments Off on It’s New York Invasive Species Awareness Week

It’s New York Invasive Species Awareness Week

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

Friday – spotted lanternfly is on our doorstep, if it’s not already here undetected. Check out spotted lanternfly trivia and help keep track of this destructive pest. (For more information, visit NYSIPM’s Spotted Lanternfly webpage.)

Here are a few other challenges that caught my eye:

The New York City Department of Environmental Protection has created the Invasive Species Backyard Bingo Challenge. I have (alas) seen many of the invasive species, but not enough to get BINGO (yay?).

The Capital Region PRISM has an EcoQuest Challenge focusing on watercress, European Frog-bit, oriental bittersweet, and swallowwort using iNaturalist.

Lower Hudson PRISM Ecoquest Challenge is focusing on Siebold’s and linden viburnum. They recommend using the Seek app to help build your identification skills and confirm your ID.

The NYS Parks Niagara Region is also using the Agents of Discovery App. They will post details on their Facebook page during ISAW.

These challenges, and more are also listed on https://nyisaw.org/events/.

And, of course, the NYS IPM Program has numerous resources on invasive species, including numerous blog posts we have written about invasive species and the recordings from our 2017 Invasive Species Conference.

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?

Comments Off on Asian Giant Hornets – A Concern for New York?

Asian Giant Hornets – A Concern for New York?

A pinned specimen of a large wasp, the Asian giant wasp from a side view.

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.

Pinned specimen of the large black and yellow Asian giant hornet, seen from above.

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 also have this defense behavior, but it is unknown how they would fare with this kind of predation. 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.

*** June 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.

*** August 2020 UPDATE

In 2020, both Washington and Canada have had new confirmed sightings of the Asian giant hornet. In addition to earlier reports, one queen, one worker and another unspecified wasp have been reported. This means we are not done with Asian giant hornets yet! Finding a queen wasp in May suggests that they survived winter in the Pacific Northwest. As colonies of these and related wasps grow in size through the end of summer, there may be more findings to report. Stay Tuned!

There are several species of wasps in the US that are very commonly confused with AGH and often killed unnecessarily:

Cicada KillerSphecius 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.

A cicada killer wasp rests on a green leaf.

European HornetVespa 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.

Baldfaced hornetDolichovespula 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.

Paper waspsPolistes 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.

NYS IPM’s Best of 2019

“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.

Blacklegged tick embedded behind knee

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.

distribution map as of November 2019

Spotted lanternfly distribution map as of November 2019

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:

We would all like the fruits and vegetables we purchase to be free of critters, and the Spotted Wing Drosophila blog post Managing SWD in raspberries & blackberries helps producers do just that.

 

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.

Readers of the The ABCs of School and Childcare Pest Management blog were itching to read about poison ivy in the blog post, Poison Ivy – Don’t scratch.

One of the benefits of blogs is the ability to provide timely information, such as the Your NEWA Blog’s most popular Spring is coming – tune up your weather stations post.

It’s been a nippy end of the autumn, so we expect the Winter Injury Spring 2019 post in the Tree Integrated Pest Management blog to remain relevant.

Not much grows in the winter in NY, unless you have a greenhouse! The Ornamental Crops IPM Blog’s popular Greenhouse IPM update 2.5.19 cover mold and biocontrol efforts that can occur in February.

So, we hope keeping up with NYS IPM Program will be included amongst your resolutions. We wish you a very happy New Year and look forward to serving you in 2020 and beyond.

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.

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).

Please download and print this CHECKLIST (below) and bring it with you as a reminder before traveling back into New York.

Checklist - 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 (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.

If you have any comments, or concerns, feel free to email me at rkp56@cornell.edu.
