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.
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.
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.
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.

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.
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 firstname.lastname@example.org with any questions!
Be sure to check the leaderboard to watch your name rise to the top as you record observations!

by Joellen Lampman Comments Off on Pollinator Friendly… Lawns?
“The dandelions and buttercups gild all the lawn: the drowsy bee stumbles among the clover tops, and summer sweetens all to me.” – James Russell Lowell
Dandelions, clover, and many other lawn weeds can help sustain pollinators.
It’s Pollinator Week, a week dedicated to halting and reversing the decline in pollinator populations and recognizing the valuable service they provide.
There are plenty of resources out there to create pollinator gardens and meadows. NYSIPM biocontrol specialist Amara Dunn has been documented an ongoing project trying to create habitat for pollinators and other beneficial insects to help support agricultural systems in her blog, Biocontrol Bytes. Head over and check out her efforts.
But what about places that can’t allow tall vegetation because of space, inability to weed areas, or aesthetics? Lindsey Christiansen, CCE Albany and I decided to explore the recommendation to create pollinator friendly lawns.
But Lindsey and I were wondering if there was a more formal way to create a pollinator friendly lawn. We searched out and found a number of seed mixes and a project was born.
“The best laid plans of mice and men…” – Robert Burns
While fall is a great time to put down seed, we solidified our plans in October, leaving us with little time. We decided to spend the remainder of autumn prepping the plots and wait until winter to put the seed down through dormant overseeding. We laid out three rows of 100 sq.ft. plots. The first row was scalped by running the CCE lawn tractor over it at its lowest height of cut. The second row was stripped using a sod cutter, and the third row was aerified multiple times using a core aerifier to break up the soil and create open soil.
The demonstration project was established in an unused part of the CCE Albany property which allows for road visibility.
Two rows were prepped using a sod cutter and aerifier rented from a local hardware store.
Removing sod cut with a sod cutter is much easier when you have good turf. The weedy lawn proved a challenge to remove.
And then it was time to wait. Ideally, we would have a stretch of bare ground in March with a few inches of snow in the forecast. So we waited. And waited some more. But it was a winter that wasn’t and as the forecast showed above average temperatures into the future, we decided to scatter the seed on March 6 with hopes that winter would provide a last gasp.
Five seed mixes were chosen for the demonstration project. For dormant overseeding, it is recommended that you double the rate, but we were sometimes restricted by the amount of seed we could purchase within our budget.
Snow cover on the dormant overseeded plots.
Winter finally threw us a bone on March 24th. The theory behind dormant overseeding is the weight of the snow pushes the seed close to the soil and as it melts into the soil, it draws the seed down with it through capillary action. The snow also protects the seed from predation. We can only guess how much seed to we lost to birds over those weeks.
And then it was time to wait again. And we were waiting in our homes due to the shutdown. So it was exciting to visit the site in early June and find baby blue eyes, dwarf California poppy, and sweet alyssum in bloom. The plot we were most worried about due to the small rate of application had the most visual pop.
The sod cut plot seeded with Alternative Lawn Wildflower Seed Mix was the most dramatic despite having the lightest rate of application.
And there were pollinators!
Solarization is an IPM technique using the sun to create high temperatures to kill existing vegetation.
We also started a fourth row, this time using solarization to prep the site. Plastic sheeting heats up the soil, killing existing plants and the seedlings of any weed seeds that germinate over the summer. We will keep the sheeting in place until it’s time to seed in the fall.
The recent hot, dry weather has not helped with establishment and there’s not currently much going on in the plots. So we are back to waiting and seeing.
And crossing our fingers that the forecast holds and we get rain by the weekend.
At the end of June, after a week of heat and humidity but no rain, there is not much flowering except for birdsfoot trefoil. For the record, birdsfoot trefoil was not in any of our seed mixes.
Many thanks to Cornell Cooperative Extension Albany County for use of the site, Lindsey Christiansen for her partnership and strong back (and for checking my math), and Matt Warnken for scalping, hauling, sod cutting, photographing, and basically making himself indispensable.

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 NYSIPM partners with The Tick App
The Tick App: Studying human behavior, tick exposure and the risk of Lyme disease using a citizen science approach via a smartphone application.
Concerned about ticks? Download The Tick App for free to join our research efforts and report your tick encounters.
If you have heard any NYS IPM Program staff talk about ticks, you have probably heard us mention that there is a lot we don’t know about ticks. Or exactly how our actions impact our risk of getting a tick-borne disease. So it is with great pleasure that we announce that we have partnered with the Diuk-Wasser lab at Columbia University and the University of Wisconsin-Madison who created The Tick App.
By downloading the app through GooglePlay or the AppStore, you will have access to information about:
ticks biology and identification
tick activity in your area
how to remove a tick
It will also help you identify ticks that you find through the Report a Tick button.
That’s a lot of information at your fingertips. The most important part of the app, however, is the daily log where you share with the team how you spent your time, what steps you took to prevent tick encounters (if any), and if you found a tick on you, a family member, or a pet. Your information is confidential and will only be shared as aggregated data based on zip code.
I have been using the app for two years and have made entering my data a daily routine, along with my daily tick check. It takes only minutes to complete.
The more people entering data, the better the team will be able to connect the dots between what we do and how that brings us in contact with ticks. We will then be able to better create recommendations to keep New Yorkers safe.
And there’s no better time as The Tick App is launching the #BattleOfTheDailyLog this June, pitching NY against other northeast and midwest states. C’mon New York! We can do this!
Don’t worry. We’ll still continue to provide tick information through the Don’t Get Ticked NY Campaign via our website, blog posts, and presentations.

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?
