A Look Back at our Beneficial Habitat Events

Photo of Betsy Lamb, Amara Dunn and Brian Eshenaur during twilight meetingOn Wednesday September 25th, Dr. Amara Dunn, Dr. Betsy Lamb, and Senior Extension Educator Brian Eshenaur hosted a Beneficial Habitat Open House. Guests could compare establishment methods, see some of the insects caught in our plots, or just enjoy the flowers.

Thursday September 26th was the Planting for Beneficial Habitat Twilight meeting. Attendees learned how habitat for pollinators and other beneficial insects show good stewardship of the land. Dr. Dunn explained several methods of establishment, the benefits of hosting pollinators and other beneficial insects, and their impact as biological control.

Revisiting wild parsnip

Wild parsnip sap can cause painful, localized burning and blistering of the skin. – New York State Department of of Environmental Conservation

Wild parsnip going to seed. The sap form this widely spreading invasive plant can cause severe burns.

Wild parsnip going to seed. The sap in this widely spreading invasive plant can cause severe burns.

A few weeks ago we discussed the invasive wild parsnip as a hidden danger for weekend weedwackers. Now it is much more obvious with its bright yellow flowers, but if you are looking to control it now, straight mowing is off the table. Some of the heads are going to seed and mowing will simply distribute those seeds, ensuring a new crop of wild parsnip next year.

Whether you choose to dig out the root, cut the root an inch or two below the soil, or mow, first cut the seed head off with clippers and put it in a plastic bag. The bag can then be left in the sun to rot the seeds before disposal. And don’t forget to wear protective clothing to prevent any sap from reaching exposed skin or eyes.

Use a boot brush to clean mud and seeds off your boots.

Use a boot brush to clean mud and seeds off your boots. Remember to check the tread!

This is also the time of year when seeds of this and other invasive species can be accidentally transported by hikers and dog walkers. Avoid brushing against plants. Check shoes, clothing, and gear after leaving an area. Remove any seeds that are found and seal them in a plastic bag. (This can double as a tick check!)

For more information on preventing the spread of invasive species while hiking, biking, camping, and, well, any outdoor play, a great resource is PlayCleanGo. And consider taking their pledge to Stop Invasive Species in Your Tracks.

Let’s stay safe out there!

Local Girl Scouts Troop Hosts Dr. Betsy Lamb of NYS IPM to Learn About Pollinators

Today’s Post is by Jaime Cummings

Girl scouts troop 40001 in Trumansburg, NY is working on their Bronze Award, which involves planning and establishing a pollinator-friendly community garden for raising awareness about the importance of pollinators in agriculture, our landscape, and community.  The girls have spent nearly 20 hours preparing for their garden, including researching the best flowers to grow, planning the layout of the garden, learning about the more than 500 species of pollinators in NY, planting seeds of many perennial flowers that benefit pollinators, and writing letters to community leaders requesting a site for the garden to raise awareness in the community.

On Earth Day, Dr. Betsy Lamb of the NYS Integrated Pest Management Program was invited to share her horticultural expertise and passion for pollinators with the girl scouts.  Dr. Lamb shared examples of the many bees, flies, butterflies, moths, bats and hummingbirds who pollinate our native, ornamental and agricultural crops in NY.  The girls learned how bees see in the ultraviolet spectrum and that many flowers are specifically designed with their particular pollinators in mind to maximize reproduction.  Dr. Lamb provided many samples of fresh flowers for the girls to dissect and to learn about flower anatomy and biology as it pertains to the various methods of pollination, which was a big hit with the girls!  She also gave some tips on garden establishment to ensure success.

The girls shared their plans for the garden with Dr. Lamb, who was impressed by the knowledge of the girls and the wide range of beneficial blooms they had selected to plant.  The garden will include 13 different types of flowers, selected with different bloom types and flowering times to feed and support pollinators from spring to fall, along with an informational sign on the benefits of pollinators and beneficial insects to our community.  The garden will be established this summer for the Trumansburg community to enjoy for years to come.  This sort of hands-on learning, fostered by Dr. Lamb, will not soon be forgotten by these girl scouts!

Thanks to Dr. Betsy Lamb, NYSIPM Ornamental IPM Coordinator

***NYSIPM staff are looking forward to photos of this pollinator garden so we hope to share them with you all as well!

Comments Off on Not Too Early to Start Planning for Pollinator Habitat

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.

Treatment Fall 2017 Spring 2018 Summer 2018 Fall 2018
A Herbicide Herbicide, transplant  Weed 2x Replace dead plants
B Herbicide Till, transplant, mulch Weed 2x Replace dead plants
C Herbicide Till, direct seed Mow 3x Mow 1x
D Herbicide Till, plant buckwheat Mow 1x, till, plant buckwheat Mow 1x, transplant
E – control Herbicide Herbicide Mow 3x Mow 1x
F Herbicide Till, lay plastic Continue solarization Remove plastic, direct seed
G Herbicide Herbicide/till 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).

Treatment Supply costs

Time

(person hrs)

A – Spring transplant $417.12 13.2
B – Spring transplant and mulch $539.29 20.4
C – Spring seeding $17.75 4.4
D – Buckwheat & fall seeding $390.55 10.3
E – Control $2.32 2.6
F – Solarize & fall seeding $148.02 10.2
G – Herbicide/tillage & fall seeding $22.04 6.3

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:

  1. Spend 2019 controlling weeds. Even where we transplanted, weed pressure was a challenge, and investing in weed control before you plant is worth it!
  2. 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.

Thanks to Betsy Lamb and Brian Eshenaur who are working on this project with me, and to Bryan Brown for doing a weed assessment for us. You can read more about this project and see more pictures from 2018 at Biocontrol Bytes. Subscribe to make sure you don’t miss future updates!

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 Unwanted Holiday Guests

Unwanted Holiday Guests

So far, the few New York state sightings of SPOTTED LANTERNFLY, a highly invasive and potentially devastating invasive insect, have been linked to their propensity to hitchhike from the quarantined areas in Pennsylvania, Maryland, Delaware and Virginia.

Our SPOTTED LANTERNFLY Fact Sheet

These discoveries have been adults thought to have traveled on vehicles or shipping materials and resulted in a quick and thorough survey of the area to locate and destroy any chance of additional insects.

This time of year, gravid adult females have probably finished laying eggs and covering them. They aren’t that fussy–they will lay eggs on any inflexible object (preferably tree bark) but it could be your vehicle, utility trailer, firewood, and more.

The responsibility to reduce the chance of infestation in New York state also lies with travelers and shippers. While the DEC does do periodic spot checking along major federal roadways, short of placing a guard station at every entry point, this means a lot of potential influx of this pest. Share the information, learn to recognize these pests and, yes, check for hitchhikers in the form of adults, nymphs and egg masses.

Once the egg mass covering has dried down from white to dull gray or grayish brown, it becomes highly camouflaged on certain surfaces like bark where its cracking mimics the surface.

Ask your friends and relatives coming in for the holidays if they are aware of this pest and refer to the many online sources:

Sorry, I Can’t Help You [grow that horribly invasive plant].

Today’s post is from Matt Frye. FYI: (He didn’t just show up on our door talking ticks or rats! And we’re glad he escaped the vines to join our program.)

Kudzu is an invasive vine that was introduced from Japan to the United States in 1876. In its heyday, kudzu was planted extensively throughout the southeastern US, where it was touted for its ability to prevent soil erosion on embankments, restore soil nitrogen (it’s a legume), and provide high quality forage for livestock. Unfortunately, like many invasive organisms introduced outside of their native range, kudzu became a pest species due to its rapid growth rate and the ability to shade out existing vegetation.

Kudzu was planted extensively on slopes for erosion control.

Based on the detrimental effects of this plant and the cost of management, kudzu is listed as a noxious weed in several states. It has also been the subject of extensive research by the US Forest Service, including my graduate research at the University of Delaware, which examined the potential for biological control of kudzu using insect natural enemies.

Kudzu vines grow up trees, over bushes, and create a dense cover of foliage that kills other plants.

In 2014 I published a slide set describing my work and experience with kudzu: why it’s a pest, some of its ecological impacts, common misconceptions, how it was grown, and how it can be killed. Since publishing this document, I have received dozens of requests for more information about the plant. What do most people want to know? How to grow it! This has been for art installations, research on allelopathy, a test to determine if kudzu can grow in zero gravity (yes, kudzu literally will be sent to space), genetic studies and for use as wildlife forage.

The last request for information to grow kudzu in New York was most alarming, and led to communication with colleagues at the New York State Department of Environmental Conservation. As it turns out – there is a regulation (6 NYCRR Part 575) that prohibits the possession, transport, importation, sale, purchase, and introduction of kudzu and other prohibited and regulated invasive species in New York (thank goodness!). And while there is a loophole for permits to be issued, these are strictly for “research, education or other approved activities.”

Can I help you to manage the plant, and offer suggestions for what to do in spaces where kudzu has been cleared? You bet! Can I help you to grow the plant for research purposes? Sure. But if your interest in growing kudzu is for non-academic purposes –I can’t help you. Sorry (not sorry).

Spotted Lanternfly: A Foe You Should Know

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. Photo by Chuck Bargeron, University of Georgia, Bugwood.org

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:

Photo by Lawrence Barringer, PA Dept. of Agriculture, Bugwood.org.

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.

 

 

Mass of lanternflies on tree. Photo by Lawrence Barringer, Pennsylvania Department of Agriculture, Bugwood.org

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.

Spotted lanternfly egg mass. Photo credit: Emelie Swackhamer, Penn State University.

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.   

DEC Press Release: Think You Found a Spotted Lanternfly in New York?

Anyone that suspects they have found SLF is encouraged to send a photo to spottedlanternfly@dec.ny.gov. 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/
