If you thought SWD was bad... This invasive is even worse! Feeding en mass, SLF suck the very life juices from plants and shower everything below with their excreted honeydew, favoring a lawn of sooty molds. Ugh. September is the month for dispersing adults — let's get ready!

The ability for the SWD population to explode as summer rolls on was demonstrated last week in several counties where I have research projects. Per trap, 5 to 125 SWD were caught in raspberry, blueberry, and tart cherry in mid-July. The totals for the two to four traps set in the orchards and fields were 14 to 250.

Use this summary as a wake up call! For the weeks ending on the date given:
7/11/2019, Schuyler County, blueberry, 4 traps, 22 SWD (11 males and 11 females)
7/11/2019, Schuyler County, raspberry, 4 traps, 108 SWD (64 males and 44 females)
7/22/2019, Herkimer County, blueberry, 4 traps, 30 SWD (12 males and 18 females)
7/22/2019, Wayne County, tart cherry, 2 traps, 14 SWD (1 male and 13 females)
7/22/2019, Wayne County, tart cherry, 2 traps, 24 SWD (4 males and 20 females)
7/22/2019, Wayne County, tart cherry, 2 traps, 57 SWD (9 males and 48 females)
7/22/2019, Wayne County, tart cherry, 2 traps, 85 SWD (19 males and 66 females)
7/22/2019, Wayne County, tart cherry, 2 traps, 250 SWD (60 males and 190 females)
7/23/2019, Wayne County, blueberry, 2 traps, 131 SWD (53 male and 78 females)
7/23/2019, Wayne County, blueberry, 4 traps, 29 SWD (14 male and 15 females)

In eight of the nine sites a spray program was in place to protect fruit. Fruit is ripe and being harvested – and it’s delicious! Fruit isn’t showing signs of infestation, which means insecticide programs can protect fruit from oviposition, even when SWD numbers are high. Download the Quick Reference Guide to SWD Insecticides at

Photo of the three instars of SWD.
The three instars of SWD will emerge from fruit immersed in a salt solution. The smallest instar is about 0.5 mm long, the largest about 2 mm long.

Salt flotation – What  these numbers also demonstrate is that trap catch numbers aren’t necessarily an indication of whether or not an insecticide program is working. A better indication is to sample fruit and run a salt flotation test. Two berry growers described their success last year using salt flotation to monitor infestations in blueberries, detailed on the blog, Use salt flotation to check for SWD.  A simple method is described in Guidelines for Checking Fruit for SWD Larvae in the Field by Laura McDermott, which can be downloaded from Cornell Fruit Resources SWD Monitoring pages, fruit.cornell.edu/spottedwing/monitoring/. Large scale berry growers will routinely run salt flotation at each harvest, because blueberries, raspberries, and blackberries ripen and are harvested over several weeks. For crops that are harvested all at once, like tart cherry, salt flotation may not be as useful.

Refrigeration – The high populations of SWD, coupled with later ripening of many crops this year, make it even more important to immediately cool fruit after harvest. Cold storage temperatures close to 32°F can greatly inhibit and even kill SWD in fruit. Raspberries, blackberries, blueberries, and tart cherries will all tolerate cold storage temperatures between 32°F to 34°F.

Diversified fruit farms – Protect your crops from SWD, if you’re growing susceptible fruit – June strawberries, day-neutral strawberries, sweet cherries, tart cherries, raspberries, blackberries, elderberries, blueberries, peaches, nectarines, plums, prunes, and thin-skinned grapes. If you have a diversified fruit farm, SWD can spill over from one crop to the next as they are harvested and especially when cull fruit remains in the field. Renovate strawberry fields promptly.

Fruit becomes susceptible to SWD oviposition when it is ripening and is highly susceptible when it is ripe – raspberry, blackberry, blueberry, sweet cherry, tart cherry, elderberry. Fruit that is less susceptible will be attacked when it is at peak ripeness – peach, nectarine, plum, prune, strawberry, grapes. All fruit can serve as a resource for feeding and breeding when it is left for cull in the field. The good news is that, in degraded fruit, SWD doesn't compete all that well with other Drosophilas, like Drosophila melanogaster, our common vinegar fly, which often shows up in our kitchens in late summer or in the winery during press. SWD prefers nice ripe fruit — like we do!

Trent Davis, Dyson School of Applied Economics and Management, and the New York State Berry Growers Association (NYSBGA) want your feedback (Cornell-NYSBGA-Labor-Survey http://bit.ly/Cornell-NYSBGA-Labor-Survey ) on labor and wage rates in berry production. The information you provide will be used to better understand what an increase in the New York State minimum wage rate from the current $11.10/hr to $15.00/hr will have on berry production in New York.

Results will be used to let the New York State government comprehend the direct impacts farmers will face with a minimum wage increase of this magnitude. Our survey is meant specifically for farmers who produce blueberries, strawberries, or raspberries.

We need to know — for 2018 — about how long certain berry production practices take, the compensation those working on these practices receive, the types of employment utilized on your farm, and potential future changes you plan for your farm.

You don't need to be a member of NYSBGA to take the survey! The more respondents the better!

The survey will take roughly 7-10 minutes. We suggest before starting the survey that you gather, or think about, the hourly wage rates you paid berry production workers in 2018.

Please complete the survey by Friday, July 12thClick this link to access the survey. Thank you so much for your participation!

Laura McDermott has coordinated an extensive network across 14 counties with the Eastern NY Commercial Horticulture Program (ENYCHP). She, along with Natasha Field, will be monitoring in Albany, Columbia, Montgomery, Rensselaer, Saratoga, Schenectady, Schoharie, and Washington counties. Collaborating on the ENYCHP are Elisabeth Hodgdon and Andy Galimberti in Clinton and Essex counties; Nat Mengaziol Orange county; Mike Principe in Putnam county; and Peter Jentsch, Hudson Valley Research Laboratory, in Dutchess and Ulster counties. Jim O'Connell, Ulster County CCE, will be monitoring in Ulster County.

In other parts of the state, Shona Ort will be monitoring in Chemung County; Dave Thorp in Livingston County; Don Gasiewicz in Wyoming County; Sharon Bachman in Erie County; and Faruque Zaman in Suffolk County, Long Island. On the Lake Ontario Fruit Program, Elizabeth Tee will monitor farms in Niagara and Orleans counties. Along with Ryan Parker, I (Juliet Carroll) will monitor SWD traps in Cayuga, Onondaga, Schuyler, and Wayne Counties.

Funding to support this effort comes from CCE County Associations and Regional Programs, the NYS IPM Program, and the NYS Berry Growers Association.

Growers monitoring their fruit plantings, researchers, and others can alert me of their findings, jec3@cornell.edu, and I'll report those on this blog.

I will also be monitoring SWD in seven tart cherry orchards in the Lake Ontario region.

SWD findings will be reported on this blog and posted to the SWD NY distribution map. Given the mild winter (except for two cold snaps...wasn't one a polar vortex?), it might be an early year for SWD arrival and build up.

Stay tuned!

A tiny blueberry stem gall wasp on a blueberry twig (magnified). Actual size about 2 mm long.

The blueberry stem gall wasp is a native insect of the Northeastern United States. While traditionally it was rarely seen in commercial blueberry production, recently increased numbers of galls have been observed in Michigan on older varieties especially 'Jersey', 'Pemberton' and 'Northland'. The increases in blueberry stem gall are likely due to a combination of changes in management.

Researchers at Michigan State University are studying control strategies, along with breeding new varieties for resistance to gall formation. To achieve this, they are looking for gall samples from across the Northeastern US.

A blueberry stem gall on 1-year-old wood as seen in late summer or early fall. After winter, by early spring, galls will have turned brown.

If you find the galls on blueberry bushes in your field, or on non-cultivated blueberry bushes around your farm, please collect them. Prune them off. Collect fresh galls on last year's wood. These are typically on small diameter twigs and are about the size of a penny.

Don't collect galls that have exit holes in them. These are usually gray, on older, dead twigs and have black exit holes about 1 mm in diameter. The tiny adult gall wasps cut their way out of the galls, around bloom time, leaving the exit holes.

Now's the best time to prune your blueberry bushes. So, while you're out there, trim off any stem galls to send to MSU. Contact Dr. Phil Fanning at fanning9@msu.edu or by phone at (517) 432-9445. Ship the galls to him at the following address:

Center for Integrated Plant Systems
578 Wilson Rd., Rm. 201
East Lansing, MI, 48824

You'll be helping minimize damage from this insect in your blueberries AND helping scientists develop better blueberry varieties.

During the Blueberry Intensive workshop in Dutchess County, we collected galls from 'Duke' and I sent them to Dr. Fanning. Thanks in advance for your help with this project!  And, no, they don't sting.

Blueberry nutrition
Feeding blueberries correctly — important and challenging: learn about crucial soil acidity (pH) and irrigation. Healthy plants better resist insects and diseases.

Post-harvest handling — reduce SWD, maintain quality
Get chill with your berries — remove field heat fast with forced air cooling. Maintain quality with modified atmosphere packaging and tools like a CoolBot.

Pruning correctly throughout the life of the planting
Like nutrition, good pruning builds an overall vigorous and pest durable plant. Learn how pruning tactics change as the plant moves through its juvenile period into the fruiting years.

Field Demonstrations!

Pest scouting and weed management 
Your top priority, season-long! At early pre-bud-break, learn what and how to look for: scale, mummyberry, and galls. Plus, weeds — timing herbicides and adding mulch.

Pruning demonstration
Hands-on opportunity! We’ll address cultivar differences in pruning approaches that will become obvious as we look at plants. Use a pneumatic pruner, as well as more traditional tools.

The Blueberry Intensive Workshop starts at 8:30 AM and ends at 4:30 PM. Lunch and breaks are included. DEC re-certification credits provided. Take home a resource packet of workshop materials you can refer back to every year.

This attractive insect sucks the life out of plants, almost literally. And, it has a broad host range, preferring trees and other woody plants - grapes and apples are of concern, but we don't know if blueberry might be at risk. Not to mention the infestations that could develop on the shade trees in your yard.

Known distribution of spotted lanternfly, as of December 2018.

New York State has external quarantines in place to try to prevent its spreading into the state from Pennsylvania and New Jersey.

Learn more about this invasive species on the NYS IPM Program's Spotted Lanternfly webpage. And don't miss one of these opportunities to learn about this insect and get your questions answered.

A wild pollinator feeding on a fall raspberry flower.

Native, non-weedy, shrub willow blooms in early spring, a time that is critical for pollinators because of the low availability of food sources.  Shrub willow supports a large diversity of pollinators that feed on its abundant pollen.  Research has shown that wild bees can be an important component of crop pollination.  Also, diversified landscapes that can provide a continuous availability of food sources best support this community of wild pollinators.

With the decline of native bees, honey bees, and managed bumble bees, pollinator services provided by the agricultural landscape are increasingly important in the production of crops, like berries, that depend on pollination.  By managing pollinator-friendly plants next to berry crops, you can enhance the services of wild pollinators and ensure adequate pollination of your berry crops, maximizing yield.

Proposed research in Horticulture and Entomology at Cornell University will involve planting and managing shrub willow next to berry crops to attract wild pollinators and then measuring the spillover effect of pollinators on berry yield — quantity and quality.  As a preamble to this promising work, the scientists want to gather grower feedback on:

  • the use of managed bees (honey bees and bumble bees) for pollination services in berries in NY
  • the need for improving pollination services for berries in NY
  • the likelihood of your adopting vegetation management strategies in non-crop areas to increase pollination.

Berry growers in NY — Please answer 10 questions in this brief, confidential Berry Pollinator Survey. No information will be shared without your permission.

The direct link to the Berry Pollinator Survey is: cornell.qualtrics.com/jfe/form/SV_2fuycOLqpAxuRVP

Want to try out the shrub willow to feed your pollinators in early spring and be a part of this research effort?  The research is currently focusing on strawberry production in NY State.  Contact Eric Fabio, esf56@cornell.edu, to find out what's possible!
