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.
You’ve all heard about them, right? Yeah, the little buggers sneak up on you, bite you, and—maybe—make you sick. Sometimes really sick.
They’re not really bugs, of course, but tiny eight-legged critters remotely related to spiders but without the benefits spiders provide. (Note that adult females plump up like small grapes once they’ve satisfied their appetite.)
Just for fun, I wrote a sentence on my finger — period and all. And yep, the larvae are that small. (Courtesy Cal Dept Public Health)
For today, we’re considering blacklegged ticks, aka the deer tick—the name it was christened with years ago, before entomologists realized that tick is already here; has been for thousands of years—and it already has a name. Yes, we’ve got a couple of other ticks we can’t ignore. But that’s for another day. Continue Reading →

by Mary M. Woodsen Comments Off on Tick Trickery
Got ticks on your mind? Your questions. Our answers:
How common are tick-borne diseases — and who is at risk?
Lyme disease is the second most common infectious disease in the entire U.S. But over 96% of all cases come from only 14 states. Now that’s scary, because New York and the Northeast are at dead center for tick trickery.
What looks like spilled ink? That’s where most ticks hang out. (CDC)
Indeed, Lyme disease is the most common vector-borne disease in the entire United States — and the second disease most commonly reported to the Centers of Disease Control, aka the CDC. (It comes right after chlamydia and before gonorrhea—both sexually transmitted diseases that could strike most anywhere.)
Each year, the CDC gets reports of about 30,000 cases of Lyme disease. But most likely that’s just a fraction of the number of cases. The CDC estimates that each year between 300,000 and 400,000 people are infected with the bacteria causing Lyme — and children ages 5 to 9 have the greatest risk. Parents, check your kids for ticks every day. Make it as mandatory as brushing teeth. “Oh, they were outside for only 10 minutes” or “Oh, but we live in a big city. How could there ticks possibly be here?” — trust us, these aren’t reasons to skip. Continue Reading →

by Mary M. Woodsen Comments Off on The low-down on ticks. Part 1A, Biology Q&A
Ticked off about ticks? You are not alone. And knowing the what, where, why, etc. is critical to knowing how to deal with them. So here it is, the first in a series: the low-down on that pest we love to hate.
May you, dear reader, stay tick-free and healthy.
1. What, exactly, is a tick?
Ticks are related to mites and spiders—but not to insects. (Now don’t go worrying about spiders—in the Northeast, virtually all are common victims of common misunderstandings.) Ticks have four life stages: egg, larvae, nymph and adult. All stages (well, not the eggs) feed on blood for energy to grow and later to reproduce. Larval ticks have six legs; nymphs and adults have eight.
Those things that look like antenna? Not—they’re highly adapted legs that process vital information. And that snout in the middle? Blood-sucking mouthparts. (Photo CDC)
Right now, three species are a health concern here in New York: the blacklegged tick, the lone star tick, and the American dog tick. Continue Reading →

by Mary M. Woodsen Comments Off on The Invasive of the Month Is … (Drum Roll)
Southeastern Pennsylvania, the epicenter of spotted lanternfly’s arrival in 2014, might seem far enough away to give us in New York prep time for dealing with this new pest, a weak flyer that usually hops to get around. But with the spotted lanternfly (Lycorma delicatula—and SLF for short), all bets are off. After all, it took over Korea, whose climate is surprisingly like our own, in no time flat. And now it’s in Maryland. Delaware. Virginia. New Jersey.
New York’s first find happened to be dead. Blind dumb luck.
A bit creepy, how cool it looks. (Photo insectimages)
How anything so pretty could be so nasty boggles the mind. But it’s the nature of nature. Since ID’ing SLF correctly is key to good IPM, let’s start with the nymphs—the young-uns. In this case they come in two snazzy colors. The early-stage nymphs are straight-on black or, once they’ve molted, black and white—handsome devils or trendy fashionistas; take your pick. For late-stage nymphs (late-stage means they molted—again—and outgrew the skin they had after they hatched), add blobs of blood-red, and that critter looks ready to conquer the world.
Which it might.
Does that bright, traffic-light red signal toxicity, as it does for many other potential prey? Right now all I know is that birds have been seen throwing up after grabbing one for a snack—and yes, they are toxic to us.
Red is ever a reminder to other critters: this might be toxic. (Photo Penn State)
Meanwhile, adult SLFs look positively benign. Lovely, in fact. Don’t believe it for a minute. These classy lads and lassies resemble butterflies or moths, but don’t believe that either—they are, you’ll recall, planthoppers; the name refers to its mode of locomotion.
Whatever. Spotted lanternflies have a destiny. Their natural expertise in the pole-vault isn’t their only way to get around. How many roads (think interstates especially) wend their way from southeastern Pennsylvania to points north, south, east and west? Lots.
Consider your car or camper, for starters. Firewood? You’d be slack-jawed at the degree to which firewood fits into the equation. Just the eggs alone—not easy to see with a cursory look—can easily hitch rides to new areas, meaning that New York is a mere hop, skip and a jump away. Trains, tractor trailers, wheel wells, the cargo hold in a jet—this pest doesn’t need to lay its eggs on organic matter. Planning a long-distance road trip? California, here we come.
“I don’t want to scare people,” says Dr. Surendra Dara, an IPM and crop advisor at the University of California, “but it has the potential to spread, and we do not have a biological-control agent.”
Which is why you, dear reader, are our eyes on the ground.
But wait. Other than toxicity, I haven’t even told you why to be alarmed about this critter. Grapes, apples, hops—these and more high-value crops rank in the billions for New York. Apples alone ring the register at about $317 million.
New York’s forestry crops are vital, too. Here’s what forest crops provide:
jobs for 49,200 people with payrolls of over $1.6 billion;
manufacturing, recreation and tourism providing over $11.0 billion to our economy;
removing greenhouse gases from the atmosphere, sequestering carbon, and producing oxygen critical for all life on earth;
filtering and buffering clean drinking water for millions of New Yorkers.
As our eyes on the ground, here’s what you need to know. Signs that spotted lanternfly are at our collective doorstep include:
sap oozing or weeping from tiny open wounds on tree trunks;
a yeasty smell (been near a brewery lately? That’s it);
inch-long, brownish-gray egg masses—like waxy mud when new, brown and scaly when old
heaps of honeydew under trees and vines and covered, often as not, with black sooty mold.
When you see this many SPFs in your orchard (this is Pennsylvania, mind you) — watch out. (Photo Smyers, Penn State)
Besides fruit and hops, what’s at risk? Everything from willows to walnuts—and smooth-barked trees especially. But keep in mind that many a mature tree which, once it has packed on the pounds around its waist and takes on a decidedly rough or furrowed look, looks svelte and clean-cut while still relatively young. Go outside and look at any gently-furrowed tree, and chances are you’re looking at a host. For those areas where tree-of-heaven runs rife, well—you’re looking at what might be its most favorite host of all.
Though it’s hard to wrap your mind around, it sups on some—maybe all—field crops. “We’ve seen it in some of the grain crops that are out there, soybean and what have you,” said Fred R. Strathmeyer Jr., Pennsylvania’s deputy secretary of agriculture. “It’s able to feed on many, many different things.”
Now think about honeydew. Not the drink, not the melon; rather the stuff bugs secrete as they feed. A case of in one end, out the other as they move down the chow line. Although native insects also secrete honeydew, the size of the SLF and staggering numbers that congregate from place to place makes for a remarkable amount of honeydew. Parked your car beneath an infested tree? Time to clean off those sticky windshield wipers.
For sure—this sticky mess and the swarms of insects it attracts gets in the way of outdoor fun. In Pennsylvania, where SLF populations are the densest, people near the heart of the problem can’t go outside without getting honeydew on their hair, clothes, and whatever they’re carrying. At which point “outdoor” and “fun” no longer have all that much in common.
So that’s it in a nutshell and, for spotted lanternfly, all the news that’s fit to print. For now.
If you’ve read our other posts on the blacklegged tick (aka the deer tick), you might guess—and rightly so—that it’s the tick that’s been on our radar the longest; the one we (still) give most of our time and attention to. And all for good reason.
Sheer numbers (how much Lyme disease we’ve seen; what the co-infections are and how commonplace they are; its reputation as the “great imitator”) keep the blacklegged tick in the spotlight. Meanwhile, with the exception of Long Island, the lone star tick is rarely seen in the metro New York area and points north. But it has colonized some islands off Connecticut and established a toehold on Cape Cod in Massachusetts.
The lone star tick is on a roll, with its own suite of diseases and syndromes, some still mysterious. (Credit CDC)
Indeed, the lone star tick’s potential for harm could, somewhere down the pike, become a force all northerners face. Continue Reading →

by Mary M. Woodsen Comments Off on The New Tick in Town (Part l.)
The aggressive lone star tick, named for the white spot on the female’s back should scare the willies out of you. Its resume includes ehrlichiosis, tularemia, the heartland virus (luckily, this virus is rare) and alpha-gal syndrome—a frankly scary allergy to red meat. And while this might be new tick in town, it’s indigenous to the southern U.S.
Could it carry Lyme disease? Highly unlikely.
Compared to a dime, this tick is mighty small, but the blacklegged tick is smaller. Courtesy CDC.
This tick is just a tad larger than the blacklegged tick. Like the blacklegged tick, it hangs out in brushy edge habitat and tall grass. It likes woodsy thickets, too. And just like the blacklegged tick, the newly-hatched larval lone star is disease-free—pure as the fallen snow. But as soon as it hatches, it’s out questing—looking for that essential blood meal it can’t live without. Continue Reading →

by Joellen Lampman Comments Off on Ticks don’t care what month it is
Last month we discussed ticks and the freezing weather. I predicted that “as soon as the temperatures rise into the mid-30s (and we know you will be out enjoying the veritable heat wave), ticks will be questing”. February 21, 2018 was an actual heat wave with temperatures reaching the mid-70s in parts of upstate NY. So in an attempt to justify spending a portion of the workday outside, tick sweeping was added to the to-do list.
26 blacklegged ticks in February

New York, like the rest of the world, is highly dependent on the hundreds of species of crop pollinators that collectively contribute roughly $170 billion a year to the global economy. Many are in decline and under threat in New York and elsewhere.
That’s why Dean Kathryn J. Boor ’80 recognized the Cornell Pollinator Health Team for their outstanding outreach accomplishments in a ceremony that celebrated research, extension and staff excellence.
On hand to accept from Dean Kathryn Boor (L) were (L-R) Jennifer Grant, Bryan Danforth, Dan Wixted and Scott McArt.
The seven-member team includes entomologists, extension outreach specialists and pest management experts — one being NYS IPM‘s director Jennifer Grant.
The team provides critical extension and outreach on pollinator declines, including information on
optimal habitats for honey bees, native bees, and other pollinators
diseases that afflict bees
how pesticides affect bees — other pollinators too
what to do when your honey bees are in decline

With its focus on extension and outreach, the team has given more than 70 extension talks over the past three years in New York and elsewhere on pollinator health, bee diversity, integrated pest management practices and pesticide recommendations that minimize risks to bees — to all pollinators, in fact. Their audiences have included beekeepers, farmers, and lawmakers — as well as state and national organizations such as the New York Farm Bureau, the Audubon Society and Future Farmers of America.
“In three short years, the work of this team has made a notable impact both in scope and relevance to beekeepers,” Boor said at the ceremony. “The pollinator health team represents a model for how collaboration among different units at Cornell can lead to highly integrative and creative extension and outreach.”

by Mary M. Woodsen Comments Off on Of pollinators and postage stamps — forever
Protect Pollinators. With these new Forever stamps, released on August 2nd, It’s all about the bees and the butterflies. Here, the monarch butterfly and western honey bee symbolize the thousands (yes, thousands) of native bees, hover and flower flies, beetles, wasps, butterflies, and moths at work throughout the Northeast, and across the continent on behalf of — well, there’s us, of course.
Two iconic pollinators. Four iconic wildflowers. Thank you, USPS.
In the U.S. roughly one-third of all food crops depend on pollinators. And of course, we do love our flowers.
But it’s not just about us. It’s about biodiversity. Consider habitat fragmentation. Example? One house at a time, a forested tract grows houses. Then five at a time; then 10. Then maybe more and wider roads, more and bigger buildings.
Fewer and fewer flowers — and their pollinators.
And habitat loss is a biggie. It makes for less forage, fewer nesting sites. For losses in abundance and diversity. For reduced genetic diversity — and increased risk of extinction. Here in New York, among bees alone two pollinators are endangered and eight more are rare.

And monarch butterflies? Starting in late summer, monarchs focus on fattening up to prepare for their epic, multi-generational migration to their overwintering site in Mexico, and it’s nectar they need. But a lawn won’t fatten them — or help other pollinators make it through the cold of a northern winter. Perhaps it’s time to consider making of your lawn an ornament of sorts, beautifully framed with flowers and meadows.
Among core values of IPM: building biodiversity. Why? Biodiversity is at the heart of healthy ecosystems. And healthy ecosystems keep us healthy too. So we thank you, USPS, for reminding us of to the beauty and importance of pollinators. All pollinators, and the biodiversity that supports them.
