Severe weather outbreaks yesterday caused intense wind and rain for prolonged periods across New York State. Significant rainfall and strong winds were recorded, with tornado warnings issued downstate in the Hudson Valley.
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.
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.

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.
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.
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.
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.
Amara Dunn was hired for the new BioControl Specialist position just about three years ago.
Since then, she’s gone from focusing on ‘learning the ropes’ and creating goals for the position… to being in high demand by staff (and New Yorkers) on both the agricultural and community sides of our program!
Amara, how does your work here at the IPM Program fit the career you imagined when you entered college?
When I started college I really had no idea what I wanted to do, except that I liked biology but didn’t want to be a medical doctor. You could say that my work at NYSIPM (across a broad range of commodities and settings) is kind of the culmination of exploring and honing my interests through a variety of professional and volunteer experiences during and after college. My eclectic job responsibilities have also reminded me that we learn something from pretty much all of our experiences, even the ones that don’t ultimately lead to a career.
Who do you see as the main audience for your current work?
I am trying very hard to provide materials for a broad range of audiences. For example, I’m doing a lot of work currently on conservation biocontrol (protecting and feeding the “good bugs” you’ve already got) and pollinators like bees and butterflies. All of these beneficial insects need the same things, but taking care of beneficial insects looks different in a back yard than it does on a farm. I’m trying to provide cost and “how-to” information for both groups. I think on some level most people I’ve interacted with – farmers, home gardeners, people who enjoy spending time outdoors – have similar questions and goals. They want to know how to solve pest problems, and they care about protecting people and the environment while they do it.
What is most rewarding about your work in pest management?
Helping people. Hands down. Being able to answer questions or provide needed information that ultimately has a positive impact on peoples’ lives brings me so much joy.
What do you most enjoy doing in your non-work time?
Broadly speaking, I would say that I like creating. I have always loved growing plants, and I’m really enjoying planning and implementing new gardens around the house I just bought. And, yes, these gardens do include plants that support beneficial insects. I’m also using them as “virtual demonstration plots” to show how one might support beneficial insects around their homes (and some of the pitfalls when trying to do this). Over the past few years, I’ve been cultivating (pun intended) an interest in cut flowers. I love having fresh flowers in my home or office, and like being able to share them with others. But I also enjoy cooking and knitting/crocheting. And I like to mix my interests. There are a wealth of patterns out there for people wanting to knit or crochet arthropods. I’ve even tried making my own pattern when I couldn’t find what I was looking for.
Given a month to travel or work on something you enjoy, where or what would it be?
Honestly, I’m pretty ambivalent about travel. I could take it or leave it. But when I do travel, I like to visit local gardens, parks, or museums and try delicious local food!
What biocontrol topic or pest problem do you anticipate on your horizon in the next year or so?
Sadly, I suspect it’s inevitable that spotted lanternfly will become established in NY. We’ve done a great job of delaying that inevitability (kudos to everyone – professionals and lay people – for all your hard work!), but it probably is an inevitability. One of the hoped-for benefits of delaying this pest’s establishment is that we’d have more tools (including biological tools) for managing it by the time it got here.
What biocontrol concern has captured your interest for future research?
I’m really interested in learning and documenting the efficacy of biocontrol strategies in the field so that we can give growers specific answers about how to use strategies to reduce risks to people and the environment. For example, how large an area of flowers, which flowers, and how close to the crop do you need to plant them to reduce pest damage? Or, which conventional pesticide sprays can be replaced with biopesticides to maintain good pest control while maintaining profitability. These are really big questions, and I certainly can’t answer them all by myself. There’s a lot of great research already being done on these questions here in NY and elsewhere.
Absolutely. Being part of the NYIPM Program lets us see so much of what’s going on regionally to reduce pest risks and help the environment! Thank you, Amara, for allowing us to share more about you and your role at the NYSIPM Program!
Amara’s office is on the Cornell AgriTech campus but you may have seen her or met her at a variety of conferences and workshops over the last three years. Follow her blog BIOCONTROL BYTES or her Twitter and professional Instagram accounts!

by Dan Olmstead Comments Off on Noteworthy rainfall across New York State this past weekend
Two major systems brought significant amounts of rain to all of New York State this past weekend. Tropical Storm Fay moved up the Hudson River Valley while a large front from the West hit western and central NY Saturday and Sunday.
7-day rainfall totals for New York State as of 12 July 2020.
Most counties and townships received a minimum half inch of rain across the state, which was timely given the fact that most of NY had transitioned to abnormally dry conditions, or moderate to severe drought in some areas, as of 10 July. Click here for additional drought status information.
More than 3 inches of rain were recorded in Catteraugus, Lewis, Madison, Oneida, Onondaga, Orange, Oswego, Rockland, Sullivan, and Westchester Counties as well as all boroughs of New York City. Smaller areas of Livingston, Monroe, Ontario, Seneca, and Yates Counties also received similar amounts.
Lumberland and Highland Townships in the southwest corner of Sullivan County may have experienced rainfall in excess of 8 inches.
In the future, visit the ThinkIPM Blog for summaries of severe weather events impacting IPM practices and agricultural production in NY.
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 email@example.com with any questions!

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 Joellen Lampman Comments Off on 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
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 Debra E. Marvin Comments Off on World BEE Day 2020
Protecting bees and other pollinators has become an important social issue. But beekeeping, and the 20,000 species of bees worldwide, have been providing livelihoods, much of our food supply, and important biodiversity for thousands of years. Today, we help celebrate the first official World Bee Day as proclaimed by the U.N. through their food and agriculture organization.
We’ve collected some of our blog posts supporting pollinator protection (see below). First, here’s some facts from the UN’s Food and Agriculture Organization:
HONEY: Honey is a nutritious, healthy and natural food produced by the bees. Its benefits go beyond its use as a sweetener as it contains several minerals, enzymes, vitamins and proteins that confer unique nutritious and organoleptic properties. Honey can be monofloral if one specific plant nectar and pollen content prevails in pre-defined percentages or polyfloral if it contains an unspecified mix of different nectars and pollens. Due to environmental, geographical and climatic conditions honey may vary in pollen content and relative humidity. Honey is produced in all five continents and its consumption varies from country to country also due to cultural reasons and eating habits.
HIVE PRODUCTS: Honey bees may provide livelihood or a source of income for many beekeepers all over the world. This could happen through the services provided by the bees (mainly pollination service, apitherapy and apitourism), or directly through the bee products. The last include: alive bees to guarantee always new queen bees or bee packs, honey, pollen, wax, propolis, royal jelly and venom. Bee products may be used as food for humans, feed for animals, cosmetics, medicines used in conventional medicine (mainly vaccination), or in apitherapy, or other like manifold products, carpentry, attractant, sweeteners, etc.
POLLINATORS: Disappearing pollinators can mean losing some of the nutritious food we need for a healthy diet. The decline of pollinators could have disastrous effects for our future of food. Their absence would jeopardize the three-quarters of the world’s crops that depend at least in part on pollination, including apples, avocadoes, pears and pumpkins. And enhancing pollination isn’t just about mitigating disaster – with improved management, pollination has the potential to increase agricultural yields and quality. Pollinators also play a crucial role in maintaining and enhancing biodiversity thus improving the resilience of plants to climate change and other environmental threats.
THE NYS IPM Program is proud to consider POLLINATOR PROTECTION part of our focus. Visit these topics on this blog, the Think IPM Blog:
Dwindling bee numbers is a problem. The question is not should we protect pollinators and create habitat, but how? What’s the best method? The most economical? The best bee habitats—made up of plants of varying sizes and bloom times—are easy on the eye. They’re also excellent real estate for other helpers, like spiders and certain beetles, that eat pests. So can pollinator habitats provide biocontrol benefits too?
To answer these questions, our team set up pollinator habitat plots around our Christmas tree research planting—testing establishment methods, evaluating weeds, counting and identifying the insects attracted, and studying the biocontrol value to the trees.
ABOVE: Flowers providing pollen or nectar are important to both pollinators and many pest-eating “beneficial” insects. You can help them by choosing a variety of plants that bloom from early spring through late fall with flowers of diverse shapes. This Echinacea makes pollen and nectar readily accessible to both small and large bees, proving that it’s not just their beauty that’s worthy of our admiration.
Wildflower and grass species favored by pollinators were chosen from lists of native perennials. Some started from seed; others were transplants. By the end of the first season, natural enemies and pollinators had arrived—including lady beetles, lacewings, predatory stink bugs, spiders, hoverflies, predatory beetles, butterflies, and many wild bees. This year the plots have matured even more. We collected flying insects with sweep nets, counted butterflies, and caught wasps and bees in brightly colored bowls of soapy water. We even had a method for catching insects moving along the ground.
So far, we have lots of tips for helping growers and gardeners create their own beneficial insect habitat. As to fewer pests in Christmas trees? Time will tell.
What’s New with NEWA?
Are summer conditions becoming more unpredictable? Are you wondering how to make informed and timely decisions about pest management? If you say yes to both, you’re not alone. NEWA, the Network for Environment and Weather Applications, is here to help by providing live, on-farm decision support for fruit, vegetable, and field crops production. NEWA pairs real-time weather data from growers’ fields with online crop-specific pest forecasting. And it’s growing every year.
Developed by scientists with pest biology expertise, NEWA models predict disease progression, insect infestations, and crop phenology. Apple growers rely on apple scab forecasts in the spring, grape growers monitor grape berry moth risk through the summer, and field corn growers track western bean cutworm flights throughout the season to know when to scout.
Our latest survey proves NEWA’s unparalleled decision support to growers is working. Users attest they saved over $4,000 in spray costs and more than $33,000 in prevented crop losses annually.
NEWA partners with extension, industry, and academic partners statewide, including the Lake Erie Regional Grape Program that supports western New York’s Concord grape growers. Thanks to the close collaboration between NYSIPM, growers, and processors, that region benefited from the addition of 11 weather stations last year, a move that nearly doubled their decision-making power. NEWA also joined forces with the NYS Mesonet at the University at Albany, a collaboration that resulted in ten pilot locations across the state.
Today NEWA offers 42 models using data from 677 weather stations in 14 states. NEWA and NYSIPM support agriculture throughout New York and beyond. The latest forecast? The future looks bright.
