Accomplishments

Participants had over 150 research reports and research & extension presentations that informed and educated stakeholders (producers, extension agents, and university and private sector scientists) of ongoing pest insect control issues in corn production.

Participants developed various extension videos on topics impacting corn pest insect control.  This included videos describing Bt resistance development and grain crop management.  Dozens of extension publications were produced or updated, including updates to managing Bt resistance, crop scouting guides, and those relating to western bean cutworm management and resistance to Bt toxins.

The Handy Bt Trait Table, available at www.texasinsects.org/bt-corn-trait-table.html, was updated to include observed field resistance among target pest species and corresponding citations in scientific literature.  This designation was added to alert producers and consultants to potential management problems and to encourage field scouting.

Impacts

  1. The impact of neonicotinoid seed treatments for corn insect control. Neonicotinoid seed treatments remain widely used in corn production. NC246 members conducted a meta-analysis for neonicotinoid efficacy across 2000-2015, and conducted a field studies measuring levels in soil and runoff. Additionally, potential yield benefits of neonicotinoid seed treatments and other management practices on corn yield were evaluated (Del Pozo-Valdivia et al. 2017). A series of review papers were included those from NC246 members that evaluated the risks of economic injuries and the benefits of seed treatments that will inform producer decisions regarding use of neonicotinoids. This information is being used by EPA as part of their benefits review for the neonicotinoid re-registration process.
  2. Emergence of Bt resistance in western bean cutworm. Field failures of Cry1F corn on western bean cutworm (WBC) were reported in Michigan, Nebraska, and Ontario during 2017, and continue to cause wide-spread crop damage and mycotoxin infections that greatly reduce grain quality and producer profits. In 2016, an open letter was sent to seed corn companies from Midwest entomologists that included NC246 participants in which they documented field-failures of Cry1F and stated they were no longer recommending this trait for WBC control. Several NC246 participants met with seed corn industry representatives to discuss methods to encourage the adaption of IPM practices in light of the ongoing resistance issues in WBC and other pest insects, which led to a change in industry recommendations for WBC control. A field screen using laboratory toxin overlay bioassays documented the high degree and broad geographic distribution of Cry1F toxin resistance across WBC populations in the Corn Belt and Great Lakes region. Nebraska Independent Crop Consultants and Michigan State Extension meetings and survey reported increased producer awareness and reports of WBC damage on Cry1F corn. This work demonstrated that a majority of producers will change or adopt new WBC resistance management recommendations, and that the information provided will improve their management decisions.
  3. Expanding international collaborations among corn insect researchers. Six NC246 participants engaged international corn researchers at the International Working Group on Ostrinia and other maize pests (IWGO) conference in Beijing, China. Presentations were given on the evolution of Bt and insecticide resistance, and insect resistance management (IRM) and integrated pest management in lepidopteran and corn rootworm pests. These contacts and information will have impact on the IRM strategies adopted by other national regulatory agencies that are in the process of approving or consider the adoption of transgenic Bt corn.
  4. Distribution and management of Asiatic garden beetle. Asiatic garden beetles (AGB) are invasive grubs that have recently been damaging young corn plants. AGB caused economic damage in many fields across MI, OH, and IN. NC246 participants are researching AGB biology and its distribution, evaluating management strategies, and discussing management options with corn growers in the afflicted regions.
  5. Evaluation of new corn rootworm control. The risk and emergence of resistance to Bt traits by corn rootworms has led to the development of newer technologies for control, including RNA-interference (RNAi) based traits. NC246 researchers have determined efficacy of these traits, as well as evaluated sub-lethal effects on related rootworm species. This research provides important information for corn producers, industry and researchers to develop sustainable practices that extend the durability of these new control tools.
  6. Determining the spread of resistance by corn insect pests. Gene flow via immigration affects rate of evolution of resistance to a pest management tactic, while emigration from a resistant population can spread resistance alleles spatially. Whether resistance detected across the landscape reflects ongoing de novo evolution in different hotspots or spread from a single focal population can determine the most effective mitigation strategy. NC246 researchers evaluated and synthesized of patterns across diverse taxa in this review clarifies the principles involved in how pest dispersal behavior at different spatial and temporal scales affects the evolution, maintenance, and spread of resistance to a control tactic. This information will be used by university, industry, and government scientists in developing effective insect resistance management and mitigation strategies for insect pests of crops, livestock, and humans.
  7. Impacts of rye cover crop on beneficial arthropods. Farmers have expanded the use of cover crops because if the benefits provided to agronomic production and soil conservation. However, there may be some unintended consequences of cover crops in corn fields. NC246 researchers determined that planting a rye cover crop appears to have minimal effects on the abundance of pest arthropods, and, in some cases, increase the number of predatory arthropods. These results means that farmers would have similar, or perhaps greater, suppression of agricultural pests by natural enemies in corn and soybean fields that were planted with a rye cover crop compared to fields without a cover crop.
  8. Monitoring for Western Corn Rootworm Resistance. Rootworms remain the largest insect threat to corn production, especially in the Western Corn Belt. Resistance to Bt traits by rootworms threatens the most widely used control tool, that has previously provided tremendous benefits for farmers. NC246 Participants monitored for resistance to several Bt traits across the corn belt to ensure that these products were performing to expectations.
  9. Survey of Helicoverpa armigera in the Florida Panhandle. The Florida Panhandle, in the Gulf Coast region, is a likely pathway for the introduction of quarantine pests, such as through the immigration flights of moths from South and Central Americans and through the terrestrial traffic of commodities. Helicoverpa armigera, a quarantine pest in the U.S., has been reported in South America since the crop season of 2012/2013. As a result of a meeting held on March 15, 2017, SERA 003 members listed this species as an IPM priority, considering its risk of introduction in the U.S. and potential economic impact. A statewide pest-monitoring network for the early detection of this quarantine pest has been performed and no occurrence of this species was detected in 2017.
