Project Summary

The subject of this proposal is research and outreach on soybean entomology in the North Central Region. This is a Year 2 renewal proposal for a 3-year proposal submitted in FY19. Year 1 progress to date encompasses October 2018 to May 2019, and we are preparing for our first field season on the project (Summer 2019). Soybean insect pests not only reduce yield, but can also reduce grain quality, altering oil and protein content (Rupe and Luttrell 2008). Thus insect pests can affect soybean value by affecting both yield and composition. In addition, inefficient pest management adds to the expense of farm production, cutting into farmers’ bottom lines. This proposal involves collaborative research among 25 researchers in 13 states, working on four main program areas encompassing I.Extension/outreach and farmer feedback, II. Insect management and profitability, III. Aphid resistant varieties and virulence management, and IV. Insect monitoring. The objectives within these programs address the efficient, cost-effective management of defoliating (chewing) insects; the role of cover crops relative to insects in soybean production; aphid resistance to insecticides (a documented and growing problem in the region); a new objective focusing on soybean stem borer (Dectes); the ability of honey bees to improve soybean yield; a public-private partnership with Corteva (formerly Pioneer Hi-Bred International) to advance aphid resistant soybean varieties for wide scale commercialization; advances in soybean breeding for aphid resistant varieties; regional monitoring programs for pest and beneficial insects; and a survey program to assess farmer priorities and needs to inform future research and extension. In addition, we have an extension objective with a dedicated budget line to produce deliverables and disseminate project results.

This project builds on past NCSRP research and investment in several important ways. Previous work on the potential for insecticide resistance in aphids and tools to measure this resistance are now being used because the insecticide-resistant soybean aphids have been found in four states, with the problem spreading each year. NCSRP research to develop aphid resistant soybean lines is nearing fruition as a major seed distributor (Corteva/Pioneer) is moving towards commercialization; the collaborative work with industry described in the current proposal will advance this effort. NCSRP research on pollinators in soybean has advanced to the point where we are ready to assess the value that honey bees may provide in soybean production (with some preliminary studies documenting the potential for substantial yield improvement). This proposal also incorporates new objectives including the role of cover crops in pest management (whether for good for for ill); the spreading problem of soybean stem borer; and maximizing the efficiency of scouting and management of defoliating insects (such as Japanese beetle, clover worm, bean leaf beetle.

The soybean team in this proposal is multi-disciplinary, with researchers in the fields of entomology, agronomy, and plant breeding. Several of our objectives are coordinated multi-state efforts making our results applicable to a broad geographic area and creating greater research efficiencies through collaboration. Finally, this proposal incorporates several new researchers in the region (new faculty at the University of Nebraska, University of Illinois, University of Missouri) and also includes established researchers who are new to the project from the University of Wisconsin, University of Kentucky, and Michigan State University – all of which increases our collaborative power and the reach of our results. The benefit for soybean farmers is that coordinated, collaborative research and outreach is the most efficient way to address insect pest problems that affect their production and profitability.
