Corn Invertebrate Pest Loss Calculator

Calculate yield and economic losses due to corn invertebrate pests

Search Criteria

Query multiple types of production and estimated yield loss data by timeframe, invertebrate pest, and geographic area*

  1. Select desired start year and end year. For a single year of data choose the same year for both start and end. 
  2. Select a pest category, which will autofill the relevant pests. 
  3. Select one or multiple pests.
  4. Further define geographic area by country, region, or select one or multiple states.
  5. Click on Search and results will display. 
  6. Further details are available by clicking on Production and Losses within results. 
  7. If specific pests or states are not selected, the output will include values for all pests and states present in the selection boxes. 
  8. NA means data not collected for that year and geographic location.

*Not all data categories may be available for all locations and all years, as outlined in the following notes.

  • These data are expert estimates only. Because data was obtained from differing sources, discrepancies among years and locations may exist that cannot be accounted for.
  • Corn loss data is available for the following states/provinces and years:
    • 2021: AL, AR, CO, DE, GA, IA, IL, KS, KY, LA, MD, MI, MN, MS, NC, ND, NE, NY, OH, SC, SD, TX, TN, VA, WI, and Ontario, Canada
    • 2022: AL, AR, CO, DE, GA, IA, IL, KS, KY, LA, MD, MI, MN, MO, MS, NC, ND, NE, NY, OH, SC, SD, TX, TN, WI, and Ontario, Canada
    • 2023: AL, AR, CO, DE, GA, IA, IL, IN, KS, KY, LA, MD, MI, MN, MO, MS, NC, ND, NE, NY, OH, SC, SD, TX, TN, VA, WI, and Ontario, Canada
    • Note: data is not available for MO in 2021 and VA in 2022.
  • Selecting regional or country-wide geographies will return results containing only the data from states and years that estimates are available for.
  • Certain invertebrate pests injure corn in multiple ways. In this loss calculator, pests were placed into the category matching their primary feeding or injury activity. For example, corn rootworm adults feed on foliage and silk while larvae feed on roots; however, corn rootworm was placed in the “Root and belowground feeders” category because it causes injury primarily to corn roots.
  • Inflation has NOT been accounted for in reported USD values.
