by Debra E. Marvin Comments Off on Not Too Early to Start Planning for Pollinator Habitat
Some of our beneficial insect habitat plots looked really beautiful this fall! Others are still works in progress.
Today’s post is from our Biocontrol Specialist, Amara Dunn
Have seed and plant catalogs started arriving in your mailbox, yet? This is the time of year I start thinking wistfully about the arrival of spring. If your spring daydreams include planting habitat for pollinators and other beneficial insects, keep reading for the latest on NYS IPM’s beneficial insect habitat establishment project!
Back in October I described the purpose and design of this project. So what have we learned after the first year? First, here’s a reminder of the different treatments we were comparing. Each treatment involved either direct seeding or transplanting habitat plants, in the spring or the fall, utilizing a different method for weed control.
Replace dead plants
Till, transplant, mulch
Replace dead plants
Till, direct seed
Till, plant buckwheat
Mow 1x, till, plant buckwheat
Mow 1x, transplant
E – control
Till, lay plastic
Remove plastic, direct seed
Herbicide 2x, till 1x
Till 1x, direct seed
And here’s how much time and money we spent on each method during our first year. Each treatment was applied to a total area of 460 ft2 (0.01 A).
A – Spring transplant
B – Spring transplant and mulch
C – Spring seeding
D – Buckwheat & fall seeding
E – Control
F – Solarize & fall seeding
G – Herbicide/tillage & fall seeding
What did we get for the time and money we invested? Well, the only two treatments that looked anything like habitat for beneficial insects by October were the ones we transplanted in the spring (A and B). And of the two, treatment B looked a lot better because of the mulch we spread around the plants after transplanting to help suppress weeds. Even so, we still hand weeded this treatment (and treatment A) twice during the year. But we got much better weed control in treatment B.
Four and a half months after transplanting, the beneficial habitat plants in treatments A (left) and B (right) were mostly growing well. But there was a big difference in weed control, in spite of similar amounts of time spent weeding each treatment
Direct-seeding in the spring resulted in a few blackeyed Susans by October (and a few partridge peas slightly earlier in the year), but did not look very impressive and had a lot of weeds.
After direct-seeding in the spring and mowing four times during the summer and fall, there were a few blackeyed Susans blooming in treatment C plots.
Of the three methods we used to manage weeds during the season, alternating herbicide applications and tillage resulted in the cleanest-looking plot by October.
A few weeds were present a week after the last time the herbicide/tillage treatment (G) was rototilled. We broadcast, raked, and pressed beneficial habitat seed into these plots.
Solarizing the soil was low-maintenance once the plastic was laid in the spring. We did learn that solarization is not a good strategy if you’re trying to control purselane. It grew just fine under our clear plastic, while most other weeds didn’t. In some places, it probably reduced the efficacy of solarization because it pushed the plastic away from the soil and allowed other weeds to germinate and grow.
In some solarized plots, purslane grew happily under the plastic. Purslane was not a common weed anywhere else in the field during the season.
The two crops of buckwheat we grew in treatment D not only suppressed weeds, but also attracted lots of pollinators and natural enemies to its blossoms before we mowed the crop down to keep it from going to seed.
The buckwheat established quickly and crowded out many weeds. We mowed the first crop in July and re-planted. We had to mow the second crop about 3 weeks before we transplanted (not ideal).
In summary, if one of your 2019 resolutions is to plant habitat for beneficial insects, I have two pieces of advice:
Spend 2019 controlling weeds. Even where we transplanted, weed pressure was a challenge, and investing in weed control before you plant is worth it!
If you have sufficient funds and need or want to establish habitat quickly, transplants are the way to go. Mulch will help you with your battle against weeds.
In 2019, we’re planning to keep monitoring these plots. Check back to see how the fall-planted and direct-seeded treatments look in their second year. Most of these methods are expected to take several years to reach their full potential. We will also start counting the insects (and insect-like creatures, like spiders) we find in these plots. During 2018, we already started seeing some beneficial insects showing up in these plots, so I’m looking forward to counting them once spring finally gets here!
Here are just a few of the beneficial insects we spotted in these plots during 2018. Soldier beetles, many hover flies, and lacewing larvae are all natural enemies of pests. We also saw lots of lady beetles and several other types of bees.

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 (email@example.com) 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.

Educator bee-guiles audiences with enthusiasm and results, earns Excellence in IPM award
A 13 year veteran of Putnam County, Lerner’s work as an invasive species educator, native plant and pollinator advocate, and turfgrass researcher has demonstrated her commitment, enthusiasm and mastery of IPM tools and tactics. Promoting IPM through education, demonstrations, and inclusive programs, Lerner has empowered her community with effective, science-based techniques.
“Jennifer Lerner’s willingness and enthusiasm for extending information to her region is legendary,” says Elizabeth Lamb, IPM Ornamentals coordinator. “She’s a gem.”
As a coordinator and collaborator for the Hudson Valley portion of the multi-year, multi-state project on keeping weeds out of sports fields on a budget, Lerner and her Turfgrass Team volunteers used “repetitive seeding” on high-use sports areas. The result? Safe playing surfaces that filled back in game after game. Why does it matter? Because we’d rather use seed than herbicides—and weeds make for slick footing and, too often, expensive falls.
Lerner also made Putnam County a leader in lily leaf beetle research. Notorious for decimating lilies, this pest is a pain for nurseries and householders alike. Enter an IPM management option: the release of a parasitoid wasp that feeds on the beetle larvae. Lerner secured a plot of land for the project, trained volunteers on the life cycle and proper handling of the wasps, and organized their successful release. Lerner’s most crucial contribution? Her outreach and clear communication skills, says project manager Brian Eshenaur.
A stalwart champion of bees and the native plants they depend on, Lerner so inspired the students from her advanced pollinators classes that they took what they learned and passed it on to over 530 community members at farmer’s markets and county fairs. And she created a special section—“Beauty and the Bees”—at the Master Gardeners’ annual plant sale. This section, now three years old, dwarfs the inventory of non-natives plants offered for sale.
There’s more, of course. Lerner also managed a demonstration pollinator garden located beside the Putnam County Department of Motor Vehicles, which attracts hundreds of patrons day in and out.
“Jen has been an important influence in promoting native plants,” says Master Gardener Janis Butler. “Whether it’s through engaging lectures, newsletter articles or in-person demonstrations, she illustrates the importance of planting natives wherever possible.”
Lerner received her award on November 14 at Cornell Cooperative Extension’s yearly in-service training in Ithaca, NY.

Ryan Parker, NYSIPM Program/Extension Aide II, has spent plenty of hours facing Spotted Wing Drosophila. Today he’s discussing the newest spotted pest.

Tree of heaven (Ailanthus altissima) is just heavenly to a spotted lanternfly (Lycorma delicatula). This invasive planthopper is sadly all but exclusive to that invasive tree, but has been found on stone fruit, blueberries, grapevine, and a smorgasbord of 70+ species as hosts. Its ability to use favorites such as hop vines and black walnut as preferential hosts for its life cycle will continue to be studied.
Perhaps it would be more accurate to call the spotted lanternfly (SLF) by its alternate name, Chinese blistering cicada. Acting to blister, fester, spread out its cute little wings and become personified as new breed of supervillain. Black widow please step away, Hollywood + spotted lanternfly = horror-able. All puns aside, everybody loves facts.
The insect has been found in 2014 in PA (now at infestation levels), DE (2018), NJ (2018), VA (2018), and NY (2018). In New York, only one insect was found at both locations (Albany and Penn Yan). NYS citizens who were knowledgeable in the identification of the insect reported the finding, proving that awareness of this pest will play a crucial role in limiting its spread.
SLF is aesthetically pleasing. Case in point:

Looks aside, its true colors show when its presence leads to crop loss, increased maintenance, and management costs. Don’t forget the reduction of a person’s quality of life and hazardous working conditions.
These insects, with all life stages present, mass on a given plant, sucking sap through their piercing-sucking mouth parts. Unlike the earlier instars, older SLF can pierce through thicker tissue. They do not feed directly on fruit, but may affect fruit quality.

While feeding, spotted lanternflies’ honeydew excrement encourages the growth of sooty mold that builds up on leaves, fruit, and around the bases of trees–especially if infestation levels are high. The presence of a fermenting odor caused by SLF feeding damage, and the sweetness of excreted honeydew also attracts nuisance insects, including wasps and flies. And sooty mold can become slippery. There is great concern about the sheer numbers of insects, because SLF abundance can be problematic for agricultural machinery and harvested products.
Spotted lanternfly lays eggs on virtually any smooth and strong surface, including plant material, stones, bricks, metal, and plastic. Thus, egg masses can be spread easily and unknowingly, and their dispersal can occur through practically any mode of transportation.

One generation occurs per year: adults develop in July, lay eggs from September-November. Overwintering egg masses—each containing 30-50 eggs—are usually covered in a waxy brown substance resembling mud. First instar nymphs emerge between May-June. First three instars are black and white; the fourth acquiring red pigments.
There is no current lure for SLF. Sentinel trees of tree of heaven are used to monitor, trap, and kill insects with systemic insecticides. Wrapping trees trunks with sticky bands, or scraping off egg masses can help. Or simply squish the nymphs and adults.
Anyone that suspects they have found SLF is encouraged to send a photo to firstname.lastname@example.org. Please note the location of where the insect was found, egg masses, and/or infestation signs. Department of Environmental Conservation (DEC) and Dept. of Ag and Markets (DAM) also encourage the public to inspect outdoor items such as vehicles, furniture, and firewood for egg masses. Anyone that visits the Pennsylvania or New Jersey Quarantine Areas should thoroughly inspect their vehicle, luggage and gear for SLF and egg masses before leaving and scrape off all egg masses.
A Smartphone application is also available to help citizens and conservation professionals quickly and easily report new invasive species sightings directly to New York’s invasive species database from their phones. For more information, visit http://www.nyimapinvasives.org/
Boxwood blight, Cylindrocladium buxicola, was first identified in 2011 when submitted samples were examined at the Connecticut Agricultural Experiment Station. This marked the first confirmed cases outside of the UK and New Zealand. Since then, it’s been found on many cultivars of boxwood, Buxus spp., up and down the east coast.

Now, it’s not only showing up in many downstate counties and Long Island, but completely decimating formal gardens and landscape nurseries. With various landscape and cutting uses, Boxwood is a million dollar plus industry, including its use as a major component in holiday wreaths and decorations.

While boxwood blight might not be a concern in your yard, you’d notice its loss in many landscapes. This is a major concern of landscapers, horticulturalists and growers.
Boxwood blight shows up as dark brown spots on leaves. These lesions enlarge with dark borders until they merge with others. By then an entire leaf—and many nearby—may be covered. These browned out or straw-colored dead leaves drop in record time. “That’s why they call it a blight.”
Stem infection also occurs and shows up as long black lesions. This FUNGAL DISEASE forms sporadochia (fruiting structures), visible with a hand lens. In layman’s terms, sporadochia produce sticky spores—nasty seeds of destruction if you’re a fungal disease! Spores happily spread by wind, rain, splashing water, or by hitchhiking on you, your lawnmower and rake, your dog, even your favorite garden birds.
Why this sudden outbreak? Anyone who suffered through this swampy summer can guess. According to Cornell Alum and New York State Climatologist, Mark Wysocki, “This is more typical for the Gulf Coast states.” Syracuse, for example, sweated through 531 hours when the dew point, a standard measure of humidity, was at least 70 degrees. That’s more than double the number of sticky hours of the next closest year, 2005.
THIS CHART SHOWS # OF HOURS OF DEWPOINT >= 70 at Ithaca Tompkins Airport by year 1996-2018
With relatively new pests, IPM and conventional treatment options aren’t time-tested. Other factors such as soil health, over or under-watering and winter injury increase susceptibility, but this year’s humidity has come at a high cost to boxwood.
For more on boxwood blight, here are two great resources:
Eat local! For towns and cities small and large, the eat-local movement is a boon for farmers and consumers alike. You (the consumer) get your veggies fresh, while you (the farmer) can build a base of local buyers who know your products.
Tomatoes, cukes, and sweet peppers. Lettuce and spinach, arugula and swiss chard. For farmers who grow them, the season is always too short—and winter too long. Now some have adopted the high-tunnel approach to get ahead of the game.
These tomatoes are just getting traction. Next up….
Ripe local tomatoes … ready for you.
And what is a high tunnel, exactly? Uh … well, I’ll grant you there’s no “exactly” to many a thing—high tunnels included. But whatever the specifics, they have much in common. For starters, this type of greenhouse is usually a plastic covered structure with less environmental control, relying on passive ventilation for cooling.
But like everything in agriculture, high-tunnel crops have can have insect pests. Plant pathogens. Weeds.
How do we help? Let us count the ways. Crafting a solid IPM plan is a great place to start. The plan lays out practices that help prevent pests, be they diseases, weeds or insects. Choosing pest-resistant varieties helps lessens the need for pesticides. Ditto with becoming familiar with a range of biocontrols while you’re still ahead of the game. Then there’s getting the ID’s right: learning the appearance or symptoms of pests that just happen to be checking out the premises. Once you’ve nailed the IDs, it’s time to scout early and often.
Diversifying and rotating crops plays a big role too. So does getting watering, ventilation, and fertilizing down to an art—a must-do, since too much or too little of any of these can encourage those pests you are trying to control.
Next time you are buying local – ask your local farmer how they include IPM in their production. You’ll find they are all doing their best to grow beautiful, delicious veggies for you.

Seasonal items will fill with water and provide mosquito breeding habitat.
So, with all the rain, it’s time for a quick yard inspection. When I conducted mine, it was too easy to find collected rainwater. The wheelbarrow was left right-side up. A snow rake tucked behind the shed was filled with water. An upside down garbage can collected water in its grooves. For these items, I simply flipped them over and the mosquito problem was solved. This simplest of IPM method is highlighted in the video, Managing Mosquito Breeding Sites, by Dr. Matt Frye.
These mosquito larvae are thriving in a driveway puddle – at least until the puddle evaporates.
Keeping an eye on the weather can also help with management decisions. Take, for example, the puddles formed in my driveway. Getting into inspection position (head down, butt up), it was easy to see the wriggling larvae. I checked the weather, saw it was going to be dry through the next day, and made the decision to let the puddle dry up. When I checked the driveway the next day, the puddle, and the mosquito larvae, were gone.
Alas, the rainy forecast will cause it to refill with water, again providing a good location for female mosquitoes to lay her eggs. Next step? Fill in the low spots in the driveway with sand to prevent standing water.
This dried puddle is no longer able to support mosquito larvae.
Diligence in monitoring is the key to preventing mosquitoes from breeding on your property. Monitor regularly and take steps to prevent standing water from becoming mosquito breeding sites.
Just last week we posted a pretty good rundown on what to do about ticks—and how. So if you need a review, just call up “Tick, Tack, Toe the Line: Lyme Disease and What to Do” and carry on from there. Remember, the basic idea is no matter which life stage they’re at, know how to protect yourself. Because you can’t count on feeling them crawling on you.
And speaking of life cycles—OK, so the blacklegged tick’s larvae have finished, the nymphs are mostly dormant right now, and the adults have yet to strut their stuff. But that’s no reason to let down your guard. If you’ve been following our posts, you know that there’s a new tick in town (and if you’re following the news, another waiting in the wings.) Their life-cycles can be different. Be watchful!
So here’s what you do:
Two years. Yup. Ticks know how to make good use of their time.
Steer clear of hitchhikers. Ticks don’t survive long in most homes because of low humidity, but still—you’re safest if you put your clothes in a clothes dryer and run it on high heat for 20 minutes. The tumbling action of the dryer and the high heat kill ticks and similar critters.
(Permethrin is an insecticide in the pyrethroid family. Pyrethroids are synthetic chemicals that act like natural extracts from the chrysanthemum flower. BTW, plants can’t run—that’s why many have evolved chemical means of protection. So say I went the DIY route, soaked some mums in oil, put the oil in a spray bottle, and spritzed my pants. But it failed to repel or kill ticks the ticks I bumped up against. Why? Mums come with a cocktail of natural chemicals inside those lovely flowers. And for permethrin and thus for repelling and killing ticks, I’d need to have the right chemicals in my brew—not to mention the know-how for making the stuff.)
Here’s your full-on tick check. Did we say to be thorough? Well, we’re saying it now.
Check for ticks. It bears repeating. Do a tick check at least once a day. Get to know the spots and bumps on your skin so you can recognize new ones. New ones that just happen to have legs.
Protect your pets. Just like people, pets can encounter ticks and acquire tick-borne disease. They can also bring ticks inside with them, which might expose you to ticks. So if your pet goes outdoors, it should have some protection against ticks. Ask your vet. And give it a tick check too—every day.
Remove ticks safely. Only one method has been officially evaluated for its ability to safely remove ticks — using sharp tweezers, grab a tick as close to the skin as possible and gently pull up. Other methods could increase the risk of acquiring a tick-borne disease. To learn more, see our post “It’s tick season. Put away the matches.”
Swimming or bathing won’t kill ticks, whether attached or not.
Ticks have a different system of breathing than humans. You can immerse them in water for hours and they won’t croak. Besides, swimming or bathing might not be enough to remove an unattached tick crawling on your body. The best way to kill a tick? Remove it safely with pointy tweezers, then place in a jar of rubbing alcohol.
And there you have it. If we don’t see you at our statewide conference Breaking the Cycle: Integrated Management of Ticks and Mosquitoes on August 7 (9 AM at the Westchester County Center, 198 Central Ave, White Plains, New York), we’ll have a video of the conference uploaded on our website soon after.
