NYS IPM’s Best of 2019

“None of us is as smart as all of us.” –Ken Blanchard

Each year, NYS IPM staff are busy blogging about relevant topics. Here’s a recap of some of our more popular 2019 offerings:

ThinkIPM is our catchall blog and a great way to keep a pulse on what’s happening in New York State IPM.

Blacklegged tick embedded behind knee

No one wants to find an embedded tick.

We have spent a lot of time in the past year talking about how to prevent tick bites, from dressing in long pants, using repellents, and conducting daily tick checks. But sometimes one gets past you and you discover that new lump behind your knee has legs. There are always question about what to do next, and Help! I found a tick on me! was the most popular 2019 blog post.

Spotted lanternfly was also on your mind, and Traveling for the Holidays? provided a checklist for those traveling within the spotted lanternfly quarantine zone. Trust us when we say that you do not want to unintentionally transport Spotted Lanternfly egg masses in New York state.

 

Other IPM Blogs – Besides ThinkIPM, we have more dedicated blogs, and you don’t need to be a specialist to subscribe to them. Here are some of the more popular posts:

We would all like the fruits and vegetables we purchase to be free of critters, and the Spotted Wing Drosophila blog post Managing SWD in raspberries & blackberries helps producers do just that.

 

The most popular Biocontrol Bytes offering was a guest post from our collegues in the Cornell’s School of Integrative Plant Science, section of Plant Pathology and Plant-Microbe Biology, Anna Wallis, Kerik Cox, and Mei-Wah Cho. They discussed moving beyond antibiotics to the use of biopesticides in the post, Battling Fire Blight with Biologicals.

Readers of the The ABCs of School and Childcare Pest Management blog were itching to read about poison ivy in the blog post, Poison Ivy – Don’t scratch.

One of the benefits of blogs is the ability to provide timely information, such as the Your NEWA Blog’s most popular Spring is coming – tune up your weather stations post.

It’s been a nippy end of the autumn, so we expect the Winter Injury Spring 2019 post in the Tree Integrated Pest Management blog to remain relevant.

Not much grows in the winter in NY, unless you have a greenhouse! The Ornamental Crops IPM Blog’s popular Greenhouse IPM update 2.5.19 cover mold and biocontrol efforts that can occur in February.

So, we hope keeping up with NYS IPM Program will be included amongst your resolutions. We wish you a very happy New Year and look forward to serving you in 2020 and beyond.

Comments Off on NEW PEST = NEW PEST PAGE

NEW PEST = NEW PEST PAGE

Looking for information on that tick that recently killed 5 cows in North Carolina? The Asian Longhorned Tick is also in NY and may threaten our dairy and livestock industries. Thanks to NYSIPM’s Field Crops and Livestock team, we welcome you to visit our new page to learn more about this serious pest and learn where you can get livestock ticks identified.

As much as we enjoy doing what we do at the NYS Integrated Pest Management Program, there are already plenty of pests to go around. Unfortunately, here’s our newest one found on our  INVASIVES page:  ASIAN LONGHORNED TICK. Haemaphysalis longicornis; ALT.

**Look for the NYS IPM booth at Empire Farm Days for more information or conversation about this tick and how it may affect your farm.

ALT is a special concern to livestock farmers!

Note: If you’re looking for long horns on this tick’s head, you’ll be disappointed. The common name is thought to come from either the spiky points on the tick’s scutum (aka shoulders), or from the points on the side of the head.

Acronyms abound in all parts of our lives. In our ‘business’, common names can be strikingly similar (Spotted Wing Drosophila, SWD, or Spotted Lanternfly, SLF) (Asian Longhorned Tick, Asian Longhorned Beetle) (Black-legged Tick, BLT, Longhorned Tick, ALT, Lone Star Tick, LST).  Hopefully by now you know IPM as Integrated Pest Management.

Biology

  • One parthenogenic female (reproduces without males) can produce hundreds or thousands of offspring
  • Cold temperature tolerance creates potential for establishment in the northeast
  • Broad host range – but prefers cattle
  • Attaching to birds and wildlife allow ALT to spread quickly over an increasing area
  • Preferred habitat:  pastures, meadows

Asian longhorned tick has short mouthparts similar to the dog tick, but its lack of any white mottling helps identify it.

Distribution

  • Native to Eastern Asia, invasive ALT became the highly problematic ‘cattle tick’ on Australia and New Zealand livestock
  • Since the 2017 discovery in New Jersey, it’s now in New York and many Northeastern states

Impact: ALT damages livestock health and impairs milk production

  • Severe infestation causes anemia or death from blood loss
  • ALT feeding can transmit bovine theileriosis and parasites that cause babesiosis
  • Theileriosis can significantly reduce milk production and kill calves

Management

  • Monitor livestock regularly for ticks – collect and submit suspicious ticks for identification
  • Typical tick insecticide treatments—ear tags, sprays, dips, pour-ons and powders—are effective against ALT
cattle with calves, many have ear tags
Livestock on pasture are particularly vulnerable to tick infestations. Check pastured animals regularly.

IPM for livestock ticks

  • Inspect animals regularly for ticks
  • When indicated, use timely application of insecticides
  • Minimize tick habitat in pasture and feedlots by keeping grasses and weeds trimmed
  • Pasture rotation
  • Deer exclusion limits re-introduction of ticks from wildlife
  • Chickens and guinea fowl in pastures eat adult ticks, but typically not nymphs
  • Opossums eat vast amounts of ticks

Consider following our WEBSITE, THINK IPM BLOG, FACEBOOK PAGE, FLICKR, or TWITTER to access all the latest news not only on this invasive pest but all our activities: 

IPM is as broad as our selection of photos. On farms, vineyards, orchards; in schools, nursing homes, playgrounds; in your own home, lawn, or garden—IPM is foundational to sound, careful, economical ways of dealing with pests.

Our Mission: The New York State Integrated Pest Management Program develops sustainable ways to manage pests and helps people to use methods that minimize environmental, health, and economic risks.

Dairy Fly IPM Demonstrations

Red barn at Shunpike Dairy

Post by Ken Wise, Livestock & Field Crops IPM Extension Area Educator

We have set up two dairy fly IPM summer-long demonstrations. The demonstrations are in Essex and Dutchess Counties. Along with Jennifer Fimbel (Dutchess County Cornell Extension Educator) and Carly Summers (Essex County Cornell Extension Educator), we have set up two summer long demonstration with Shunpike Dairy   and North Country Creamery  Dairy.

There are several species of flies that cause cattle problems and we break them into two categories: barn flies and pasture flies. In the barn we have stable flies (biting) and house flies (non-biting), and on pasture we have stable flies (biting), horn flies (biting), face flies (non-biting), horse flies (biting) and deer flies (biting).

Photo of public area in front of North Country Creamery

Barn Flies: Both house and stable flies reproduce and develop in moist, rotting organic matter. This includes moist hay, straw, manure, feed or any rotting material in contact with the ground (soil or concrete). Stable flies need to take blood meals to reproduce. These flies like to bite the legs of the animals. Houseflies do not bite but can occur at high numbers. They annoy the animals and can transmit various diseases.

Keeping areas around the barn clear of this organic matter reduces barn fly issues dramatically. BUT…Even while keeping barns clean, these flies can still become problematic as the summer progresses.

The use of biological control can help keep populations lower if you start in the early summer. Releasing specific parasitoids around the barns works like smart bombs by laying eggs inside of the pupa of stable and house flies. They hatch and will eat the pupa before it can an adult fly. There are many types of fly traps that can be employed to control barn flies. You can purchase parasitoids for weekly releases from IPM Labs .

We have set up several fly traps for demonstration to aid in controlling these flies in or around the barns to monitor fly populations and efficacy of the various traps for the summer.

PRO SERIES SPIDERWEB™ FLY GLUE TRAP (AKA Giant Glue Trap) (house flies and some possible stable flies)

Olsen Biting Fly Trap  (stable flies are attracted to a blue spectrum of light that is reflected)

Photo shows a large round cylinder up right like a large water pipe. The surface is sticky and many flies are stuck to it. It's placed outside on the ground.

Insecticides can be used in the barn if threshold levels have been met or exceeded. Place 3 by 5-inch spot cards in different areas of the barn where flies congregate. When houseflies rest they regurgitate their food and leave a spot on the wall, or in this case the card.  If a card receives 100 spots per card per week, it has reached the action threshold. Make every attempt to find where the flies are breeding and reproducing and eliminate the moist organic matter. If there is still a problem, and only as a last resort, an insecticide can be used.  (Make sure you read and follow the insecticide label before use)

Pasture Flies: While stable flies breed in moist organic matter horn and face flies reproduce in fresh cow pats. Within a minute or so, after a cow defecates, the flies lay eggs in the pat. Horn flies live 90 percent of the time on cattle and need blood to reproduce. Each fly can take 20 blood meals a day. That is a lot of biting on the animals. Face flies feed on secretions from the animal around the eyes and nose.  They will also feed on a wound or cut. Face flies also transmit pink eye and infect animals with a nematode eye worm (Thelasia sp.). Horn flies can be controlled with a walk through trap (Bruce Trap) or a Cow Vac. A second method is to drag a light harrow to spread out the manure pat and make it thin and dry out. This will kill the fly maggots in the manure pat.

Walk through trap (Bruce Trap)

This photo shows a screened in passageway outside, large enough for cattle to pass through. Text on the photo says Horn and faceflies do not like enclosures and fly off toward lights near the outer netting and are trapped.

Cow Vac

Photo shows a sturdy passageway with a motor on top that acts as a vacuum as cows pass through the enclosed passageway.

The flies can also be controlled with insecticides if certain thresholds have been met.  The threshold for face fly is an average of 10 flies per face across the herd and horn fly is an average of 50 per side of the animal. Note that horn flies are ½ the size of the house fly, and feed on the back, side or belly of the cattle.  The threshold for stable flies in the barn or on pasture is an average of 10 flies per 4 legs. You will need to monitor about 15 animals in the herd to determine thresholds.

This photo shows another angle of the cow vacuum passageway.

There are also horse and deer flies (both biting flies) that can feed on cattle. While they occur to a lesser degree that other cattle flies they do take blood meals and are very painful. They reproduce in wet areas in and around forests. They will land on the cattle, take blood and leave in seconds. This is why insecticides do not work on these two biting flies, because there is not enough exposure to the insecticide. We set up two traps that catch stable, horse and deer flies on each farm.

H-Trap

This photo shows an outdoor trap that is suspended on a curved pole. The trap is a very large black ball with a netted, peaked canopy over it. Flies are attracted to the black ball and then fly up into the netted trap.

Horse Pal Trap

This photos shows the Horsepal trap. Similar to the H trap, it is set outdoors and consists of a large black ball covered with a tented canopy that traps flies as they fly up from the ball.

We will host field meetings in association with the demonstrations during which we will demonstrate and discuss IPM for flies on cattle and general pasture management. Meeting dates will be posted soon.

An #IPM Field Trip

Recently, our Livestock & Field Crops IPM Extension Area Educator, Ken Wise did a guest lecture in the Cornell IPM class taught by Dr. Toni DiTomasso and Dr. John Losey.  But Ken didn’t only stand in front of the chalkboard (or white board); he did a hands-on lecture on fly pest management at the new teaching dairy facility near campus.

Forty or so student were present for the educational tour which happened to coincide with a very recent birth.

Livestock & Field Crops Coordinator Jaime Cummings was along: “Ken shared his 20 years of experience in livestock IPM education with Cornell undergrads on identifying and managing fly pests. Students showed their interest with many good questions and were excited at the opportunity to tour the teaching dairy facility, where the calves were a big hit in drumming up interest in NY dairy production!”

For more on Dairy fly management, the NYSIPM Program has a full list of video playlists including LIVESTOCK IPM.

2018’s Best of NYS IPM

“None of us is as smart as all of us.” –Ken Blanchard

2018 has been quite the year and we have been busy blogging, tweeting, videoing, and Facebooking about it. Here’s a recap of some of our more popular 2018 offerings:

ThinkIPM – our catchall blog and a great way to keep a pulse on what’s happening in New York State IPM.

Our most popular blog post was actually a guest blog by Paul Hetzler, CCE St. Lawrence County, Move Over, Medusa: Pretty? Poisonous! in the Caterpillar Clan. We’re big fans of his writing and this post on a venomous caterpillar caught a lot of your attention as well. (photo credit: Wikimedia Commons)

 

Are you safe now?

Ticks in February?

Ticks in the cold was also a popular topic. And relevant to now! Check out these two blog posts, Ticks don’t care what month it is and Ticks and the freezing weather. Hopefully they both convince you to keep up your daily tick checks.

While visiting our blog, you have also been checking out older posts. Our second most popular post viewed in 2018 was a 2014 post, Identifying Your Pest – with Poop?. There are a lot of budding scatologists out there.

Other IPM Blogs – Besides ThinkIPM, we have more dedicated blogs, and you don’t need to be a specialist to subscribe to them. Here are some of the more popular posts:

The Spotted Wing Drosophila blog has an obvious focus, but the post Spotted lanternfly found in two counties in NY captured the most views.

 

Biocontrol Bytes was begun at the end of 2018 and many of you have been enjoying the updates on the Creating habitat for beneficial insects project.

 

We saw a number of news reports about bed bugs in schools, so we wrote Bed bugs in schools aren’t going away in The ABCs of School and Childcare Pest Management blog. And you read it. We just wish the news reporters and commenters did too.

 

The 2017 NEWA Survey: IPM impact includes such gems as “93% agreed or strongly agreed that NEWA pest forecast information enhances IPM decision-making for their crops”.

 

Gypsy moths on Christmas trees? Check out the Tree Integrated Pest Management blog and see how it’s now a thing in the Gypsy Moth Caterpillars -Scout for them now post.

 

Facebook

When it comes to Facebook, video rules. Our most popular Facebook post was our claymation video, Life Cycle of the Blacklegged Tick (and Lyme Disease Prevention!). And, by the way, this claymation was part of a large Don’t Get Ticked NY campaign launched in 2018!

Our new Spotted Lanternfly video, Have YOU Spotted Lanternfly Egg Masses was just posted, but it has already reached the number two spot. This invasive insect is getting a lot of attention and we need your help to keep track of it in New York.

 

Twitter

We’re not surprised that our most popular Tweet of 2018 was about spotted lanternfly. Follow us on Twitter to keep up with the latest information.

 

 

 

Annual Report

This might be cheating, because it was just released and we have no data to show its popularity, but our 2017-2018 annual report is a 2019 calendar and everyone we have shown it to has been pretty excited.

Here’s a picture of the spotted lanternfly you have been hearing about.

 

 

 

 

 

 

 

So, as we raise our glasses to 2018 and look forward to 2019, include keeping up with NYS IPM Program amongst your resolutions.

Happy New Year!

Comments Off on Seed Selection for Resistance to Insects and Diseases

Seed Selection for Resistance to Insects and Diseases

Today’s post is authored by  Jaime Cummings, NYS IPM Field Crops and Livestock

Whether planting a home garden or a one hundred acre soybean field, it’s important to consider all the pest, weed and disease issues that may occur during the growing season.  We have many tools in the IPM toolkit to help us manage these issues, including crop rotation, hand weeding, reliance on natural predators, and use of exclusion barriers, insect traps and pesticides.  But one of the most important cultural practices everyone should consider as a first line of defense against pests and diseases is genetic resistance in the varieties you select to grow.

Selective breeding, or genetic modification, for improved harvests has been occurring since the beginning of agriculture, and all modern crops have been modified in some way from their wild ancestor plants.  Think about corn, also known as maize, as one familiar example.  All modern corn was derived from the ancestral grass called teosinte through selective breeding by our ancestors (Figure 1).  Many advancements in breeding methods and technologies have developed in recent decades, but the goal is the same:  To develop elite varieties that are well-adapted to specific regions with resistance to common diseases and pests to achieve high yields.  We now have a wide range of corn varieties and hybrids with different maturities, different colored and sized kernels, and different levels of resistance to a wide variety of pests and diseases (Figure 2).  Some modern corn hybrids even have specific traits or genes that enable them to tolerate certain herbicides or to ward off some insect pests.  All these breeding advancements have resulted in improved yields and decreased pesticide use.  And there are many other disease resistance genes that have been discovered and integrated into many corn varieties.  These too have significantly reduced farmers’ reliance on pesticides for managing diseases and the harmful mycotoxins produced by some pathogenic fungi.

Figure 1. 

Teosinte is the wild plant that all modern corn originated from 8,700 years ago.  (Image from National Geographic)

Figure 2. 

Diversity in corn varieties developed through selective breeding efforts.  (Image from USDA)

Corn is just one example among all the crops we grow with options for genetic resistance to numerous pests and diseases.  We have similar opportunities when selecting varieties for our fruits, vegetables and grains (Figures 3 and 4).  Choose wisely and consider the advantages of selecting varieties with resistance.  Many insects and diseases plague our crops that are challenging to manage, with or without the natural or synthetic pesticides used in organic or non-organic agricultural systems.  To improve your chances of success in minimizing losses, consider all the strategies of integrated pest management, starting with the seeds you select to plant.

Figure 4.

Soybean varieties that are susceptible (left) and resistant (right) to aphids.  (Image from University of Minnesota)

Whether developed through traditional selective breeding methods or high-tech genetic engineering, all of our crops have been modified from their original form to provide us with improved feed, fiber and fuel yields.  When selecting varieties to plant in your garden or on your farm, take advantage of these breeding advancements, and consider choosing varieties with resistance to the pests and diseases that are commonly problematic in your area.  You’ll be glad you did when you have fewer bugs chomping on your crops and fewer losses to those unsightly molds and mildews.

Comments Off on An Exotic Tick Could be Very Bad News

An Exotic Tick Could be Very Bad News

Some scientists consider the epidemic of tick-borne disease in the Northeast one of the region’s greatest natural disasters. As if the risks were not bad enough already, there is a newly emerging concern. In the fall of 2017, officials in New Jersey confirmed the discovery of a new species of tick on a sheep farm in Hunterdon County. This tick, known as the longhorned tick or East Asian tick, has now been discovered in New Jersey, Virginia, West Virginia, North Carolina, Arkansas and, recently, New York. Native to China, Korea, Japan and Pacific islands and nations, the longhorned tick has only been known to science for about nine years and is thought to have been in the United States since at least 2010.

So what is the risk? The longhorned tick feeds on a wide range of mammals and birds, including cattle, sheep pigs, chickens as well as bear, deer, fox, rabbits, smaller mammals and wild birds. It also feeds on dogs, cats and humans. This tick spreads quickly through herds of domestic and wild animals. It may have arrived in the US through human travel or the transport of animals, as the USDA has intercepted specimens at inspection points in US ports. Wild migratory birds can carry these ticks, and so can animals that move great distances, such as coyotes. Even though it has been discovered in just a handful of states, the longhorned tick is likely much more widespread.

An interesting aspect of the biology of longhorned ticks is that females can reproduce asexually through a process known as parthenogenesis. Females do not need to seek a mate and can reproduce quickly and spread rapidly into new areas. It is a cold-tolerant species that can overwinter, and therefore it is expected to spread northward.

The longhorned tick is capable of transmitting diseases to livestock animals, including horses, sheep and cows. This means a significant risk to the dairy and livestock industry from tick-borne theileriosis, a malaria-like disease that results in anemia and possible death of cattle and sheep.

This exotic tick can also carry a few serious disease organisms that affect humans but we still do not know if it can transmit those pathogens to people. In one recent case, a child in New Jersey found a longhorned tick crawling on her body, but was not bitten. That tick tested negative for known pathogens.  However, a single tick specimen cannot define the disease risk that we might face, so we need more information.

Anyone who encounters a tick is encouraged to have the tick identified by a professional. This is especially true for ticks that seem out of the ordinary. Longhorned ticks are difficult to identify, especially in the younger stages. Adults are plain brown but look similar to brown dog ticks. You can submit ticks for identification to one of the tick ID services listed at the bottom of this webpage: http://www.neregionalvectorcenter.com/ticks.

Prevent tick bites to minimize the risks of becoming infected. Learn more about tick bite prevention and tick management at the NYS IPM Program’s Tick webpage: www.dontgettickedny.org.

For more details about the exotic longhorned tick, see the Northeast Regional Center for Excellence in Vector-Borne Diseases fact sheet: http://neregionalvectorcenter.com/longhorned-tick
