Great Lakes Urban Agriculture Working Group 2024 Achievements

This was a busy year for the Great Lakes Urban Agriculture Working Group! The team published 15 pest cards focused on mammals and insects that can cause problems when growing crops in urban areas. Three virtual urban farm tours were also produced, including a photograph tour and video summaries. Maggie Rivera and Dr. Laura Ingwell promoted the team’s activities during the May Pests and Progress webinar, and an annual meeting was held to promote networking and information sharing. Learn more and get involved with these additional details!

Teaching Biocontrol of Invasive Species

The North Central School IPM Working Group recently used two new invasive species curricula in Chicago-area schools. Todd Breitenfeldt, biological weed control expert and retired science teacher, taught students about phragmites, spotted knapweed and Asian jumping worms. Learning activities were tailored to the ages of the students and included participants from both elementaries and high schools. The full jumping worm and phragmites curricula will be available via the online Pest Defense classes.

US Fish & Wildlife Service Update

Here’s the latest news from the US Fish and Wildlife Service.

Fish and Wildlife Service Proposes Endangered Species Act Protection for Monarch Butterfly

The U.S. Fish and Wildlife Service has proposed listing the monarch butterfly as a threatened species under the Endangered Species Act. The “threatened” designation allows species-specific protections that would apply in both public and private lands within the contiguous United States, Puerto Rico and the U.S. Virgin Islands. Hawaii and other U.S. territories are not included because they are outside of the historical range of the species.

Under the proposed “threatened” status, these activities would still be allowed:

  • Maintenance, enhancement, removal or establishment of milkweed and nectar plants within the monarch’s breeding and migratory range
  • Implementation of conservation plans developed by state or federal agencies
  • Maintenance or improvement of monarch overwintering habitat in the United States when following an approved plan
  • Non-lethal collection, possession, captive-rearing, and release of 250 or fewer monarchs per year
  • Non-lethal scientific research and educational activities involving 250 or fewer monarchs per year
  • Possession of dead monarchs
  • Sale of 250 or fewer captive-reared monarchs

The proposed listing is open for public comment for 90 days, which ends on March 12, 2025. The USFWS is particularly interested in comments about the need to include an exception for impact on monarchs associated with the use of pesticides.

Two public sessions are scheduled:

  • Tuesday, January 14, 2025, from 6:00 to 8:30 p.m. ET (5:00 p.m. to 7:30 p.m. CT)
  • Wednesday, January 15, 2025, from 8:00 to 10:30 p.m. ET (7:00 to 9:30 p.m. CT)

IPM Highlights

Here’s interesting stories related to progress in integrated pest management.

ESA Monarch Listing Decision Toolkit

Now that the monarch is proposed for listing as threatened under the Endangered Species Act, you may wonder how these changes affect farmers and landowners. Fortunately, the Farmers for Monarchs organization has resources available to help you understand what the proposed listing means and how you can provide feedback about the proposed rules related to the threatened status. These resources are available in the ESA Listing Decision Toolkit.

Can Genetic Engineering Reverse Insecticide Resistance?

Is resistance reversible? Typically, when resistance to a pesticide develops in a pest population, the trait is retained even if it is no longer needed. Recent research in Drosophila flies shows potential as researchers are able to perform lab trials where the wild-type allele becomes more common despite the presence of a  resistance gene.  This may allow wild-type alleles to increase in the Drosophila population so the flies remain vulnerable to insecticide as a control method.

Help with Bulletins Live! Two is Available in Michigan

Pesticide labels now require applicators to check the Bulletins Live! Two website before spraying. Michigan State University Extension is offering six free, hands-on training sessions to help you learn how to use the new website. These sessions will include 50-minute presentations along with personalized, one-on-one training using the Bulletins Live! Two website.

Sessions are free, but space is limited so be sure to register.

Spotted-Wing Drosophila Impact Survey

Small fruit grower expertise is needed! What are the impacts of spotted-wing drosophila (SWD) on your farm? How have these impacts changed in the last decade? Please fill out this short survey (which will take 15 minutes or less) or share this survey with your contacts. The deadline is late February.

A national team of entomologists is working to understand where challenges still exist for SWD management and what improvements have been made over the last 10 years. Insights will be used to develop new research goals as part of a USDA Specialty Crop Research Initiative proposal. Results will also be shared in extension and research publications.

Agronomy & Farm Management Podcast: Dealing with DON

Deoxynivalenol (DON) is a vomitoxin produced by a fungus that grows on corn ears. Levels of this toxin are tested at grain elevators before corn is sold, and its presence can affect profits (and even whether the crop can be sold). This is your chance to go behind the scenes of grain operations to look at testing, grain flow and market impacts of DON. Tips for DON management are also included.

Tool From The SCN Coalition Reveals the Pest’s Financial Toll

Soybean cyst nematode (SCN) is considered the most yield-limiting disease of soybean in the U.S. and Canada, but do you know how much it is affecting your profits? This calculator can help you estimate how much SCN is impacting your bottom line based on a few basic details you provide, such as an SCN egg count, the sand content of the soil and soil pH.

Integrated Pest Management in Swine Production Facilities

Insect bites can have large impacts on market swine health and thus profits. The bites can cause skin lesions that can result in as much as $6-$15/head trim loss in packing plants in the upper Midwest. Learn how to set up your facility and maintain the grounds to keep insect populations low. Other strategies for control, such as ventilation and insecticides, are included.

Plant Risk Evaluator Tool

The Plant Risk Evaluator Tool is an online database that describes the potential for ornamental and horticultural plants to become invasive weeds in different areas and environments. The goal of this tool is to prevent new weed pests by helping landscapers and garden centers avoid species with invasive potential.

Identification of the Pan-Allergen Tropomyosin from the Common Bed Bug

Tropomyosin is a protein that exists in all animals, but the tropomyosin in invertebrates is especially allergenic to humans. This recent study, published in Scientific Reports, demonstrates that common bed bugs (Cimex lectularius) contain tropomyosin and that infestations could lead to allergic reactions. Levels of tropomyosin were measured in bed bug bodies, feces, and exuviae (cast skins). Levels were measured over time to see if levels increased or declined. Finally, bed bug treatments were trialed to determine whether they effectively remediated tropomyosin levels as well.

Using Fungi to Control Soybean Cyst Nematode

This project explored the symbiotic relationships between soybean cyst nematodes and the fungi they carry. Some of these fungi were found to infect soybean cyst nematode eggs or reduce movement of the juvenile worms. Other fungi may help control the soybean cyst nematode by preventing the nematode from infecting a plant or inhibiting its development inside the plant.

Meet Amblyseius swirskii (Acari: Phytoseiidae): A Commonly used Predatory Mite in Vegetable Crops

The predatory mite, Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae), is a biological control agent that has been commercially available since 2005. This predatory mite has become one of the most popular biocontrol predators worldwide because it is an effective generalist predator that feeds on multiple soft-bodied insects and mite pest species. It can be used to suppress whitefly populations (Hemiptera: Aleyrodidae), thrips (Thysanoptera), and spider mites. The presence of this mite can benefit vegetables like peppers, eggplants, cucumbers, and squash and ornamentals like roses and chrysanthemums in fields and greenhouses.
