One bug at a time: how biocontrol helps you, even in winter

Sure it’s winter. But many greenhouse growers work year-round. And what’s this about biocontrols? In fields, orchards, vineyards, and greenhouses—especially greenhouses—biocontrols are the predators and parasites that keep pests in check, minus the pesticides. What’s special about greenhouses? They’re where pests consistently find plenty of food, just-right temperatures, and little to stop them from bounding out of control. The linchpin that drives the search for alternatives to pesticides? Consumer demand.

Looks like sawdust—but it’s really bran infused with the tiny eggs or larvae of beneficial insects.

Which is where biocontrols fit in. These critters evolved to eat pests for breakfast, lunch and dinner. But there’s a learning curve involved. You can’t bring in the good guys and call it a day. Use a broad-spectrum pesticide and you’ll do them in. Which is why an Extension educator in the six-county New York Capitol District crafted a series of workshops to help growers get the hang of that seemingly simple IPM practice: biocontrol.

Since seeing is believing, growers attended a series of workshops where they saw start-to-finish biocontrol in action. What did they learn?

Examples

  • how to distribute marigolds throughout their greenhouses as a thrips (bad guy) magnet
  • how to apply a nematode drench to control the fungus gnats that eat roots
  • which 17 biocontrols can collectively cope with 21 bad guys
  • how the IPM Greenhouse Scout app helps you choose among them

Little sachets are another way greenhouse growers can introduce those tiny, good-guy bugs to the posies that need them.

As for consumer demand? People worry about pesticides on their posies. In theory, biocontrol appeals to them. But they haven’t seen it in action. If they see bugs, any bugs, good guys included—they might worry. That’s why a simple, colorful flier is part of the package, helping growers bring the message back to their base—their customers.

We give awards: IPM, excellence, and Julie Suarez

True — this media release dates back to January 4. But that’s not so long ago, and for someone like Julie Suarez it bears repeating. In short: we presented Julie (whom you’ll meet in a minute) with an Excellence in IPM award for—well, we could name a host of reasons. But we’ll let this speak to some of the best.

GENEVA, NY, January 4, 2018: Julie Suarez’s passion is people. People at work, people at home, people in need. Whether it’s about the farm or urban communities, she’s keenly aware of the pests and the problems. She knows the issues, the legislators, the associations and nonprofits. She’s a natural.

Now Suarez, assistant dean of Governmental and Community Relations at Cornell University’s College of Agriculture and Life Sciences (CALS), has received an Excellence in IPM award from the New York State Integrated Pest Management Program (NYSIPM) for her unstinting advocacy for the people and programs at Cornell on issues that matter to all New Yorkers.

An accomplished facilitator, Suarez helps people

  • deal with invasive pests that threaten the livelihood of many farmers
  • preserve the pollinators—the honey bees and their kin—that are key to growing fruits and vegetables worth $1.15 billion to New York’s economy
  • cope with the relentless pressure of ticks and tick-borne diseases, which affected an estimated 8,000 New Yorkers in 2017 alone

Accolades for Suarez include:

  • Julie was instrumental in addressing the crisis when a new pest, a tiny fruit fly the size of a pinhead, threatened to put berry farmers out of business. She would answer questions, provide guidance and inform—usually responding to emails within minutes. I don’t know how she did it.
  • Julie reached out to me about research on pollinator health as soon as I arrived at Cornell. I’m impressed with the breadth and depth of her knowledge and her ability to work with scientists, officials and stakeholder groups statewide.
  • Julie is keenly aware of the key issues for state legislators, noting the committees they serve on and the needs of their constituents. That’s how the NYSIPM Program became involved with the Senate Task Force on Lyme and Tick-Borne Disease.

“Julie is proactive, strengthening the bonds between  the  IPM  Program  and the community at large,” says New York Senator Sue Serino, herself a leader in the fight against Lyme disease. “She consistently exceeds the expectations of those around her.”

“Julie brings legislators in Albany to Cornell and Cornell researchers to the legislators. She gets it that programs like ours take science to the people,” says Jennifer Grant, director of NYSIPM. “It’s a privilege working with Julie to serve all New York’s citizens.”

Suarez received her Excellence in IPM award on January 4 at the NYS Agricultural Society’s Annual Forum in Syracuse, NY. Learn more about IPM at nysipm.cornell.edu.

Pollinators, awards — and IPM

Just one short week ago, we celebrated the College of Agriculture and Life Science at Cornell University’s Outstanding Accomplishments in Extension and Outreach Award. This award honors a team effort that benefits an important segment of the population or area of the state.

It takes teamwork — whether you’re a bee or a researcher. (Photo Sasha Israel)

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.

Pollinator Team at the 2017 CALS Award Ceremony

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.”

It’s (still) tick season — and will be evermore

Sorry to bring up a sore subject, but it’s still tick season. And will be all year round. What … during winter? Really? Yes. But for starters here’s your pop quiz:

A tick’s lifespan is

  • three months
  • ten months
  • twenty-four months (that is, about two years)

The best way to remove a tick is to

  • swab it with nail polish
  • hold a hot match to its behind
  • pull it straight up with fine-point tweezers

Even 15 million years ago, it was tick season. Trapped in amber, this tick carries Lyme-causing bacteria. (Photo credit Oregon State University.)

But back to our intro. Here’s the scoop: an adult female that hasn’t yet managed to grab hold of a large animal (think deer — or person) to get that all-important blood meal (can’t lay eggs without it) doesn’t want to wait around till a sunshiny summer day next year, because by then its number is up. Besides, the mice, chipmunks or birds it fed on earlier in its life cycle have only so much blood to go around. So that tick stays just below the soil where tall meadow flowers or low shrubs grow. Waiting. Waiting for a thaw barely long enough for it to scramble up one of those stems.

Waiting for the cues that tell it a warm-blooded animal is at close range. An animal that might be you.

And now for a look at our quiz. A tick’s lifespan? Your answer is (drumroll) C: upward of two years. Here’s how it works: Ticks spend a lot of time in dormancy, aka diapause. Eggs are laid in spring, tucked away out of sight. If some critter doesn’t find and eat them, they’ll hatch during summer as larval ticks (seed ticks, they’re sometimes called). Larval ticks are not infected with Lyme when they hatch — indeed, they’re pure as the fallen snow.

Meanwhile if likely hosts — those mice, chipmunks or birds — wander by, the ticks latch on. And if a host is already infected with Lyme disease or any of its nasty co-infections, those larval ticks, pure no more, are infected too.

Look close and you’ll see that spring, summer, fall, winter … every season is tick season. (Image credit Florida Dept. Health)

Larvae that make it this far morph into nymphs, and it’s diapause season again as the nymphs wait it out till the following spring. Assuming these ticks are now carriers —and about 25% will be — spring is the worst time of year for us. Because these ticks are tiny enough (the infamous poppy-seed stage) that they’re easy to overlook. If you get bit, ipso facto — you get Lyme (and quite possibly a co-infection too).

Things slack off in late summer as surviving nymphs enter a diapause that lasts till the following spring. But you can’t let down your guard, since by mid-fall through winter you’ve got those adult ticks to consider. The good thing (if “good thing” there is)? While half of these sesame seed-sized ticks are infected, they’re also easier to spot and remove.

Our second  quiz item? If any of these strike you as valuable folk wisdom, strike the valuable part and know it ain’t so. Nail polish? Matches? Don’t even think of it. Those first two items are just likely to tick that tick off — and it’ll vomit its gut contents into you in its hurry to get out. That is, if it can get out quickly; if it’s really drilled in, it has downloaded a cement-like substance to anchor itself. It takes some doing to disengage, however persuasive the nail polish, burnt match, or myriad other folklore remedies. (Twisting it is another no-no that comes to mind, mainly because someone asked me about it mid-way through this post.)

Pointy tweezers, held right against your skin and gripping the mouthparts, are the way to go. (Image credit tickencounter.org)

If you value your health, get yourself some pointy tweezers, sold for needlepoint and other crafts, and carry them with you always in your bag, backpack, or whatever you haul around. Grasp that tick as close as you can get to your skin and pull steadily. Did its mouthparts remain glued within? Not to worry — the tick will feed no more. And before too many days go by, your exfoliating skin (that’s when the top layer of skin cells drift away) will exfoliate them in turn.

With ticks, prevention can include everything from doing routine tick checks to wearing repellent clothing when you’re outdoors — regardless the season. And you can’t do much better than this for advice about dressing right.

Meanwhile here’s your catchphrase: 32, ticks on you. “32” as in 32°F. Stay watchful — and stay safe.

Comments Off on Steer Clear of Ticks and the Diseases They Carry — the IPM Way

Steer Clear of Ticks and the Diseases They Carry — the IPM Way

These days if you live near anything green — a suburban development, however humble or high-class; a neighborhood park where shrubs and meadow flowers grow — best you’d read up on ticks, be they black-legged ticks (aka deer ticks) or lone-star ticks (so named for the silvery white dot on the female’s back). While you’re at it, read up on Lyme disease and its suite of co-infections, some nastier even than Lyme.

And know this: no magic spray or treatment will eliminate ticks.

Researchers are investigating area-wide tick management options (The Tick Project) and working to understand how habitat management (The Tick Management Handbook; Japanese Barberry Control Methods) and host management (mice, deer) affect tick populations. But it’s up to you to protect yourself — knowing that prevention is the best cure.

  1. Wear tick-killing clothing. Buy over-the-counter permethrin spray and spray it on your clothing and gear. Used according to the label, permethrin binds to the material and can kill ticks, mosquitoes and other pests following a lethal exposure. Do-it-yourself treatments can remain effective for up to seven washes. Also consider buying pretreated cloths or sending your outdoor socks, pants, and shirts for professional treatments. These can be protected for up to 70 washes.

    Follow label instructions for do-it-yourself clothing treatments.

  2. Use repellants. DEET, picaridin, oil of lemon eucalyptus and IR3535 all repel ticks. The percentage of active ingredient on the label indicates how long that product will be active in the field. For more on choosing the right repellant see our previous post, “Understanding over-the-counter sprays for mosquitoes and ticks” (June 2, 2015) and this guide from Consumers Reports.
  3. Ticks wait for a passing host on vegetation or in leaf litter. Staying on trails can reduce your exposure to ticks.

    Recognize and avoid tick habitat.Tick species differ in where they prefer to hang out. The blacklegged tick (transmits Lyme disease) is found at adult knee-height and below in wooded or brushy areas. When hiking, stay on the trail and away from these areas. If you’ll be in tick habitat, take precautions by wearing long pants tucked into your socks and a light-colored shirt tucked into pants. These steps make it more difficult for ticks to get to your skin. If you’ve treated your clothing with permethrin, this can also increase the exposure of the ticks to the acaracide — the tick-killing substance.

  4. Steer clear of hitchhikers. 

    Isolate exposed items in large, zippered plastic bags to avoid bringing ticks indoors.

    Ticks can be carried on clothing or gear that you used outdoors — gear that you haven’t used permethrin or a repellent on. True, ticks don’t survive long in most homes because of low humidity, but still — you’re safest if you change your clothes and place exposed items in a large, zippered plastic bag in an entryway. Put them in a clothes dryer and run on high heat for 20 minutes. The tumbling action of the dryer and the high heat kill ticks and similar critters. [Note: don’t wash clothes first. Even the hottest cycle might not kill ticks, and it increases the drying time needed.]

  5. Check for ticks. Taking all these steps doesn’t mean you will avoid ticks 100% of the time. Perform daily tick checks even if you haven’t been outdoors in a day or so. Get to know the marks on your skin and recognize new ones. New marks that, if you touch them, just happen to have legs.
  6. 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.
  7. Protect your pets.

    Grooming after outdoor activity with a fine-toothed brush can remove ticks in pet fur.

    Just like people, pets can encounter ticks and acquire tick-borne disease. If your pet goes outdoors, it should have some protection against ticks. TickEncounter describes some of the options available for your pets, including oral and spot-on medications as well as collars. Speak to your veterinarian about the best option for protecting your pet against tick bites. Regular grooming with a fine-tooth comb after being outdoors can help to remove ticks that have not attached to your pet’s skin.

Comments Off on In praise of messiness

In praise of messiness

KEMPTVILLE, ONTARIO. — On my twice-monthly drive on Highway 416 between Prescott and Ottawa, I pass the sign for Kemptville, a town of about 3,500 which lies roughly 40 km north of the St. Lawrence. It has a rich history, and no doubt is a fine place to live, but one of these days I need to stop there to verify that Kemptville is in fact a village of surpassing tidiness. (It’s Exit 34 in case anyone wants to take some field notes and get back to me.)

Most of us would prefer not to live in totally unkempt surroundings, but Western culture may have taken sanitation a bit too far. Claims that cleanliness is next to godliness have yet to be proven by science, but research does indicate a neat, well-coiffed landscape is bad for bees and other pollinators.

Dandelions are an essential early-season flowers for our 416 species of wild bees in New York.

With all due respect to honeybees, they are seldom required to produce fruits and vegetables. Please don’t spread this around, as I do not want to tarnish their public image. But the fact is that wild bees, along with other insects and the odd vertebrate here and there, do a bang-up job pollinating our crops, provided there are enough types of wild plants (i.e., messiness) around to keep them happy for the rest of the season.

As landscapes become neater and less diverse, wild bees cannot find enough natural foods to keep them in the neighborhood for the few weeks of the year we’d like them to wallow around in our apple or cucumber flowers. In sterile, highly manipulated environments like almond groves and suburban tracts, honeybees are critical.

Dr. Scott McArt, a bee specialist at Cornell’s Dyce Laboratory for Bee Research, says there are an estimated 416 species of wild bees in New York State. When I estimate stuff, the numbers tend to be less exact, such as “more than three,” but I’ve met Dr. McArt, and I trust him on this count. Dr. McArt is quick to point out that wild critters take care of things just fine in most places. He has cataloged exactly 110 species of wild bees visiting apple blossoms in commercial orchards, and in the vast majority of NYS orchards studied, honeybees have no bearing on pollination rates. My object is not to malign honeybees, but to point out that if we learn to live with a bit more unkemptness, we will improve the health of wild bees, wildflowers, food crops, and ourselves in the process.

Dr. McArt has cataloged exactly 110 species of wild bees visiting apple blossoms in commercial orchards, and in the vast majority of NYS orchards studied, honeybees have no bearing on pollination rates. There was a presentation about it at the 2015 Pollinator Conference.

Messiness also takes pressure off managed honeybees, an increasingly fragile species, by providing them a rich source of wild, non-sprayed nectar and pollen. Orchardists do not spray insecticides when their crops are flowering because they know it will kill bees. But many fungicides, which are not intended to kill insects, are sprayed during bloom. One of the unexpected findings of research done through the Dyce Lab is that non-lethal sprays like fungicides are directly linked with the decline of both wild bees and honeybees. But banning a particular chemical is not a panacea—the situation is far more complex than that. What is needed to save bees of all stripes is a real change in mindset regarding landscape aesthetics.

This garden at Bethpage State Park Golf Course is an excellent example of entropy. Primarily established with native wildflowers, there are also a significant number of volunteers. NYS IPM staff found over 100 different species of insects, primarily bees and wasps, taking advantage of the bounty.

Increasing the entropy on one’s property is as easy as falling off a log (which of course is a literal example of increased entropy). Pollinators need plants which bloom at all different times, grow at various heights, and have a multitude of flower shapes and structures. For greater abundance and diversity of wild flowering plants, all you need to do is stop. Stop constantly mowing everything. Choose some places to mow once a year in the late fall, and others where you will mow every second third year. Stop using herbicides, both the broadleaf kind and the non-selective type.

Before you know it, elderberry and raspberry will spring up. Woody plants like dogwoods and viburnums will start to appear. Coltsfoot and dandelions, essential early-season flowers, will come back. Asters and goldenrod (which by the way do not cause allergies), highly important late-season sources of nectar and pollen, will likewise return.

Despite their unassuming flowers, Virginia creeper attracts a large number of pollinating bees and wasps. Photo: Joellen Lampman

Wild grape, virgin’s bower, Virginia creeper and wild cucumber will ramble around, without any help whatsoever. However, you may choose to help this process along by sowing perennial or self-seeding wildflowers like purple coneflower, foxglove, bee balm, mint, or lupine. Even dandelion is worth planting. You’ll not only get more wild pollinators, you’ll also see more birds. Redstarts, tanagers, orioles, hummingbirds, catbirds, waxwings and more will be attracted to such glorious neglect. No feeders required.

I strongly advocate for more chaos in the plant department, even if the local Chamber of Commerce or Tourism Board frowns upon it. Remember, just because you’re an unkempt community doesn’t mean you have to change the name of your town.

Many thanks to Paul for letting us share his piece! For more information on protecting pollinators and enhancing their habitat, visit the New York State Integrated Pest Management Program’s pollinators webpage.

Comments Off on 35,500 western bean cutworms later, it’s a record year for IPM in corn

35,500 western bean cutworms later, it’s a record year for IPM in corn

Got a sweet tooth for sweetcorn? You’re in good company. So should you hear rumors on the wind about wormy sweetcorn — or field corn or dry beans (the kind you put in your soup kettle) and you’re curious about what’s behind them, here’s the scoop:

The western bean cutworm (just call it “WBC”), a recent invasive, is making waves in the midwestern and eastern corn belts. This pest made landfall in New York’s million-plus acres of field corn in 2010, its numbers spiraling ever upward since. This year, though, has been a record-breaker. WBC has become a pest we can count on for a long time to come.

To cope with WBC, the New York State IPM Program coordinates a “pheromone trap network” for WBC in field corn; in dry beans too. A second IPM trap network focuses on sweetcorn, though it also traps for WBC in beans.

But what is a pheromone and how does the network work? Think of pheromones as scents that insects send wafting on the wind to alert others in their tribe that something important is happening — and the time to act is now. In this case, pheromones are the “come hither” perfumes female moths use to advertise for mates.

Trapped — one more male out looking for a date.

But lures imbued with chemical replicates of pheromones can intercept males on their quest, dooming them to a very different fate. IPM scouts strategically place special trap buckets around corn and bean fields.  Each contains a “kill strip” treated with an insecticide. Farmers, Extension educators, and crop consultants check the buckets each week to count their take.

And though it’s their larvae — the worms — that give WBC its name, here we’re counting the adults; in this case, moths.

It’s traps — and scouts — like these that do the job.

This year the two networks combined have caught more than 35,500 moths — far more than in any other year. Those in the know, know — this is not good. WBC is a sneaky critter. It even eats its eggshells as soon as it hatches, removing evidence that it’s out and about. Meanwhile, trap network numbers can vary considerably from county to county; even from farm to farm. Regardless, when armed with counts in their area farmers know when it’s time to ramp up scouting their fields. Because once they’ve reached threshold — the IPM “do-something” point — it’s time to act.

Why wait till a field reaches threshold? Because sprays are expensive — both to the farmers’ bottom line and the environment.  Because time is money too; spending it needlessly out on a rig does no favors. Because treating only at need is one very good way to keep all these costs as low as can be.

Because — it’s what IPM is here for.

Comments Off on Weed control specialist joins NYS IPM

Weed control specialist joins NYS IPM

Bryan Brown

Bryan Brown, Ph.D., is the new Integrated Weed Management Specialist

I’m Bryan Brown, the new Integrated Weed Management Specialist at NYS IPM. I’m thrilled to have this opportunity to work with growers and promote IPM solutions for weed management. I came here from the University of Maine, where I compared the economic and ecological effects of several weed management strategies and tested a new cultivation technology that uses several tools, sometimes in tandem, to target the in-row zone.

Integrated weed management

No single weed control tactic is completely effective. And relying on one single tactic is how weeds develop resistance. So what we need to do is integrate more tactics. Attack weeds in as many ways as possible. For conventional growers, a basic step is to use a range of herbicides with different modes of action. Other direct controls include cultivation, flaming, mowing, and biocontrol.

Less direct tactics can also make a huge difference in weed control effectiveness. For example, crop rotation allows for use of different herbicides, fertility, and tillage dates — all of which can be adjusted to combat certain weed species. Likewise, crop cultivar and plant spacing can be altered to maximize competitiveness with weeds, and cover-crop residues can lessen weed emergence. Growers can be even more successful with these practices if they are used to target the biology and life cycle of their most problematic weeds.

When many growers think about weeds, they think of big nasty plants. But I like to encourage growers to think about weed seeds. The number of weed seeds in the soil is very important to the success of weed control tactics. Even if you kill 99% of the weeds in your crop, if you start with 1,000 germinating weed seeds per square foot (yes, that’s common), ten of those weeds will survive and compete with your crop. So depleting the number of weed seeds in the soil is key to effective management. As is often the case in IPM, an ounce of prevention is worth a pound of cure.

How do you reduce the number of weed seeds in the soil? Control weeds before they produce seed, mow crop boarders to prevent seeds from blowing in, and use seed-free fertilizers. You can also create a stale seedbed by encouraging weed seeds to germinate, then killing them before planting. With these techniques, some farmers have sharply reduced the number of weed seeds in their soil, improving their in-season weed control.

Next steps

I’m especially interested in finding weed management solutions that have multiple benefits. For example, cultivation kills weeds but can also be used to increase nitrogen mineralization, improve water infiltration, and control soil-dwelling pests like cutworms. Cover-crop residue can suppress weeds but it can also increase soil organic matter, interfere with navigation of some insect pests, and reduce splashing of soil-borne pathogens. So perhaps weed management can be integrated with management of soils, pathogens, and insect pests?

Comments Off on Getting ticked? Bummed about Lyme disease? You’re not alone

Getting ticked? Bummed about Lyme disease? You’re not alone

An NYS IPM Your NEWA Blog entry dropped into my inbox a couple of days ago — and since the entire conversation on my bus ride into work today was about ticks, a topic no one seemed to tire of, I just had to borrow from it for this post.

Here’s how it begins:

“Getting ticked? You’re not the only one.” That’s my colleague Dan Olmstead speaking. He continues:

“I was at Empire Farm Days working the New York State IPM Program booth last week. What do you think the most asked-about topic was?

“Every question I answered was about ticks. Ticks are most well-known as carriers of Lyme disease and they are on the rise. Changing weather and climate patterns could be partly to blame. Growing seasons are getting longer and ticks have more time to develop.”

Dan goes on to explain that range expansion is another likely factor coinciding with increasing numbers of mice and deer. These critters do well in fragmented habitat, whether it’s overgrown field, hedgerows — or expanding suburbs.

Mice infected with Lyme transmit it to the young ticks that feed on them. Meanwhile deer (birds too) pick up ticks in one place and ferry them to new, perhaps un-infested locations — making them complicit in transmitting Lyme disease despite the fact that, at least on deer, Lyme-free ticks (and yes, such ticks exist) won’t contract Lyme by feeding on deer.

But the black-legged tick (aka deer tick), host to Lyme disease and several other nasty co-infections, isn’t the only dog in the fight. It has friends — as it were. Here (courtesy the Centers for Disease Control) are the ticks we see and the most common diseases now associated with them:

Black-legged Ticks  Lyme, Anaplasmosis, Babesiosis and Powassan virus
Lone Star Ticks    Erlichiosis, STARI, and Tularemia
American Dog Ticks   Tularemia and Rocky Mountain Spotted Fever
Brown Dog Ticks Rocky Mountain Spotted Fever

When Empire Farm Days rolled around in early August, the tiny nymphs — the most dangerous stage for us humans — were still at it, still clambering onto the tall grasses and low brush or meadow plants that they’d perched on most every chance they got since May. They were waiting for the right host to come by. It’s called questing. And yes, these ticks are — metaphorically at least — on a quest that for them means life or death. (Most die but plenty remain.)

True, by now in late August, their populations have peaked. But even so they’re still eight-armed and dangerous.

Eight-armed? OK — make that eight-legged.

And typically by early August, it’s too hot and dry anyway for ticks to quest for hosts. But by early August this year, our colleague Joellen Lampman hadn’t seen the usual summer decline in black-legged tick questing. Ticks like to quest when humidity is greater than 85%, and 2017 assuredly hasn’t been stingy on that account.

Got ticks on your mind? Bummed because you’re stuck inside and feel like you can’t get out in the woods like you used to? Worried because deer have found your neighborhood, regardless how populated your neighborhood? Wondering how best to protect yourself? Seek no further: Tick Encounter is your one-stop shopping for everything you need to know. Check it out.

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.
