Project Summary

The subject of this proposal is research and outreach on soybean entomology in the North Central Region. This is a Year 3 renewal proposal for a 3-year proposal submitted in FY19. Year 2 is currently underway, as we prepare for the second field season of the project (Summer 2020). 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); management of 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; 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 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 yield improvement that honey bees may provide in soybean production. This proposal also has objectives looking at the role of cover crops in pest management; 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).

Final Project Results

Benefit to Soybean Farmers

The soybean team in this proposal is multi-disciplinary, with researchers in the fields of entomology, agronomy, and plant pathology. 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. 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.
