Title: Creating a Regional Trapping Network for Corn Rootworm Adults
Abstract: Corn rootworm is a serious economic pest of corn throughout the North Central region, and this pest can be persistent, especially in areas with continuous corn production. Management continues to be challenging as corn rootworms readily adapt to limited management strategies. In 2021, a network was established that included university, industry, and government personnel from 12 states and 5 provinces to provide a unified message about corn rootworm management and develop a shared protocol for monitoring corn rootworm adults across our wide geography. The goals of the trapping network were to increase scouting efforts in corn, understand changes across years, and identify any trends across the region. This trapping effort is ongoing, but highlights from the 2021 trapping network will be shared.

Title: IPM Extension Educator & IPM Co-coordinator
Organization: University of Minnesota
Title: Region-wide Surveys and Pest Forecasting for Advancing Minnesota IPM
Abstract: Efficient pest management revolves around understanding what’s actually developing in individual fields. Are specific pests even present? Is it even the right time of year to be looking? Are there actually high enough populations to be concerned about? Keeping these questions in mind is vital for any integrated pest management program while determining when to scout. While scouting your own fields is the gold standard for insect management decisions, region-wide surveys and pest forecasts can help growers stay aware of pest threats as they happen in order to determine when focused scouting is needed. This session will introduce tools available to growers through University of Minnesota Extension that aid scouting efforts in the state and region, such as the spring and summer western MN IPM survey for small grains and soybeans, the fall European corn borer survey, and degree-day maps for forecasting pest development and critical scouting time. Minnesota’s cold winters also play a role in reducing insect populations.

Title: Adapting the Wisconsin IPM Program to the “New Normal” in Outreach Delivery: Successes, Challenges and a Balanced Way Forward
Abstract: The University of Wisconsin Integrated Pest Management (UW IPM) Program has a long history of providing stakeholder-driven educational programming efforts since its inception in 1979. Given the long history, we’ve developed and continue to deliver foundational programs that are highly anticipated by clientele, such as hands-on Scout Schools and the experiential learning Custom Applicator Program. However, in the past 1.5 years of IPM programming during COVID-19 in-person restrictions we’ve “test driven” several new outreach delivery mechanisms. While we certainly won’t abandon in-person programs, the recent need to move programming online has revealed significant opportunities to deliver efficient, timely and impactful outreach to diverse and broad audiences. In addition, this modernized delivery pairs well with the current succession to the next generation of farmers and recent investments in improved statewide rural broadband access.
Moving forward, we look to strike a balance between continuing traditional outreach programs that are expected and valued by stakeholders and developing and delivering interactive and engaging online programming. In this presentation I will share recent successes, challenges and ideas for IPM extension in the “new normal” of outreach programming.

Title: Illinois IPM program Highlights and Future Directions
Abstract: The EIP-funded IPM program supports surveys, demonstrations, and education focused on invasive species, pest management, and pollinator protection in Illinois. The University of Illinois Extension and the Natural History Survey have been major components of past IPM grants and continue to play a key role in education and outreach for this program. Focusing on pollinator protection, bee numbers and species diversity were compared across nature preserves and former farmland which had been converted into conservation habitats to get a better idea of what species are present in Illinois and in what numbers, and to determine if conservation habitats support similar bee populations as native ecosystems. A youth pollinator education program was also developed from this project, while a website focused on pollinator education and protection in collaboration with University of Illinois Extension educators is in development. Field crop scouting schools focused on pest identification and damage and threshold evaluations were postponed due to the pandemic but are planned for the future, along with new and updated agronomic pest factsheets.
The IPM program works closely with other pest management programs at the University to provide support and dissemination of their work. Surveys in cooperation with the Illinois Cooperative Agriculture Pest Survey are conducted every year to monitor the presence and numbers of invasive pests in agronomic and specialty crops. Educational materials are produced about these pests, including identification aids and management recommendations. The IPM program also supports the University of Illinois Plant Clinic which processes samples from across Illinois and the United States, identifying pests and pathogens and providing research-based management recommendations for these issues. Plant Clinic personnel also provide education about plant health management for invasive and endemic pests and pathogens to the general public, agronomic producers, and green industry professionals. The IPM program uses newsletters, social media, field days, presentations, and workshops to broadcast information about effective, economical, and environmentally-friendly pest management. Future goals include expanding the pollinator website, producing a handbook of pests and pathogens of hemp in Illinois, surveying corn rootworm populations, and continuing education about invasive species and pest management in Illinois.

Title: Missouri IPM Highlights
Abstract: With its central location, Missouri is a keystone state for pest invasion from all directions, and wide-ranging environmental conditions within a single season challenge even the best plant growers. Research and curriculum developed by MU faculty in the Missouri IPM Program, which is shared with the public through MU Extension, is designed to aid in plant production to maximize benefit to society while avoiding detriments caused by unnecessary inputs. This project focuses mainly on management of weeds, diseases and insects in agriculture. Recent issues with synthetic auxin drift damage have spurred several research and associated outreach efforts to understand the symptoms and various reactions of plant species to drift damage. A wide reaching “Scouting Schools” program provides on-farm demonstrations of pathogen identification, with emphasis on fungicide resistance management and assessment of the distribution of emerging disease issues. Research involving a novel system for using impregnated netting for insect control instead of spray applications could reduce insecticide exposure for our critical pollinator species. Binding this all together is the framework of the MU IPM program, with a social media presence and broad website that hosts a pest monitoring network, three newsletters, various other publications, web applications and services.

Title: Developing a Novel Mechanical Strategy for Control of Billbug
Abstract: Billbug damage to turf in many parts of the United States has become more problematic in recent years due to the emergence of a nation-wide collage of billbug species. Novel species interactions have resulted in the development of regional billbug pest complexes, with poorly understood seasonal biology. The lack of a decision-making tool, both for larval and adult populations, has resulted in heavy reliance on prophylactic and often misguided insecticide applications. This unprejudiced insecticide application not only resulted in poor control of billbug populations, but also increased risk of environmental safety to humans, natural enemies, and beneficial species like pollinators, as well as an elevated economic burden for professional turfgrass managers. This collaborative project among turf specialists and entomologists from three states seeks to develop innovative and sustainable approaches for the management of billbug in the urban environment using a mechanical tactic. In this presentation, we will report our progress made on three objectives: 1. develop a Degree-Day model that predicts the biofix of billbug adults; 2. validate and utilize a genetic tool that allow identification of billbug larvae; and 3. develop innovative and sustainable IPM tactics by using a turf sweeper, which was initially designed for synthetic turf surfaces.

Title: Using Research-Based Solutions for Integrated Management of White Mold in Soybeans
Abstract: White mold, caused by the fungus Sclerotinia sclerotiorum is one of the most important diseases of soybean in the Midwest U.S. In the last five seasons, white mold has resulted in more than 36 million bushels of yield loss in the North Central IPM Center states alone. Management of white mold is complicated and requires a multi-pronged approach. Researchers in the Midwest U.S. have been working to refine the integrated management strategy for white mold, which includes using resistant varieties, modifying row spacing and planting population, crop rotation, biological controls, and fungicide applications. To assist in making fungicide application decisions, researchers have also developed innovative smartphone prediction tools. The smartphone application (app) Sporecaster is freely available and can be used specifically to predict white mold at a specific location. This presentation will outline the latest white mold research-based tools and showcase how these tools have been integrated together to improve white mold management of soybeans.

Title: A Push-Pull Strategy to Manage Stable Flies
Abstract: Stable flies are global pests of cattle and in the U.S. are estimated to cause economic losses of 2.2 B USD annually. Although early researchers designed and tested various stable fly trap designs relying on visual attraction to panels, cloths, or cylinders of various materials they have not been widely used. Instead, stable fly management has largely relied on insecticides in a few modes of action classes. Because of concerns about developing or potential development of insecticide resistance there is a need for alternative control products. This study investigated the use of a biopesticide with repellent and contact toxicity to stable flies as a push tactic coupled with stable fly traps that are visually and olfactorily attractive as a pull tactic. In two years of field testing, the Push-Pull strategy was compared to positive (permethrin) and negative (untreated) control treatments using a six-week, repeated measures design. We found that the Push-Pull treatment performed the same as the permethrin treatment when measured seasonally, by study weeks, and by days in a week and in all cases differed from the untreated control. Stable fly trap improvements have also been tested by varying attractant concentration, release methods, and placements. Results have been inconsistent and additional trap trials will be done in the 2021 fly season. The Push-Pull strategy offers cattle producers a low-impact, alternative to standard insecticides to control stable flies in large pasture systems common to the Great Plains and elsewhere.

Title: When invasive pests disrupt IPM - responding to gall wasp outbreak in highbush blueberries
Abstract: The western region of Michigan is a prime location for production of highbush blueberries, with over 22,000 acres of this crop being produced for the fresh, frozen, and processed food markets. Due to the market expectation for perfect fruit, growers employ intensive IPM programs to prevent economic loss from insects, with primary focus on those that directly reduce yields and contaminate harvested fruit. High quality blueberries are achieved through a combination of cultural controls, monitoring, biological control, and insecticides. Implementation of blueberry IPM programs focused on blueberry maggot, fruitworms, and Japanese beetle led to a significant reduction in insecticide use during the early part of this century, but arrival of spotted-wing Drosophila caused a disruption of established IPM programs with many unintended consequences. This presentation will discuss some of those changes that happened to berry IPM programs over the last decade, and how research, extension, and grower communities have responded. As an example, I will highlight our work to address blueberry stem gall wasp, a native insect that has become more abundant over the past decade and the multi-disciplinary team that has been seeking solutions to this pest.
Biography: Dr. Isaacs is a Professor and Extension Specialist at Michigan State University where he leads the Berry Crops Entomology laboratory in the Department of Entomology (College of Agriculture & Natural Resources).

Title: Diversifying IPM after harvest: The promise of implementing insecticide netting to protect stored product
Abstract: Globally, $100 billion USD in postharvest commodities are lost due to insect feeding and damage. Control of these insects has historically relied on fumigation, but there are increasing regulatory, consumer, and biological constraints on the use of fumigants. As a result, there has been a push to diversify integrated pest management (IPM) after harvest. In our project, we have quickly assessed and supported adoption of long-lasting insecticide-incorporated netting (LLIN) in stored product IPM programs. We have found that exposure to deltamethrin netting results in a 2–3-fold reduction in movement and 95–100% reduction in dispersal after contact by multiple species and life stages of stored product insects compared to controls. Moreover, we have found that direct mortality ranged from 73–98% for 5 of 8 stored product species after brief 5-minute exposures to the insecticide netting. Further, deployment of insecticide netting via one of three methods in pilot-scale warehouses resulted in a 93% reduction in infestation and 99% fewer progreny produced in commodities after releasing thousands of insects compared to control warehouses containing netting with no insecticide. We found the netting can be successfully incorporated into an attract-and-kill trap to intercept stored product insects on the perimeter of facilities. Importantly, we found that multiple brief exposures to the net result in the same effects on stored product insects as longer, continuous exposures. We have worked with the producer of LLIN label it for use in postharvest settings in the US. Finally, there has been robust interest by stakeholders in adopting netting at food facilities across the Great Plains. Taken together, our project has successfully demonstrated the ability for insecticide netting to act as an effective novel tactic, while diversifying IPM programs at food facilities across the US to protect our commodities as they make their way to the end consumer.
