Soybean Insect Loss Calculator

Calculate yield and economic losses due to soybean insects

Search Criteria


**Data from this calculator does not include economic costs associated with insect management, such as field scouting and insecticide application.**

Query multiple types of production and estimated yield loss data by timeframe, insect 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 an insect pest category, which will autofill the relevant insect pests. 
  3. Select one or multiple insect 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 insect pests or states are not selected, the output will include values for all insect pests and states present in the selection boxes. 
  8. NA means data not collected for that year and geographic location.

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

  • These data are expert estimates only.
  • Soybean loss data is available for the following states and years:
    • 2009 and 2010: AR, MS, and TN
    • 2011 through 2016: AL, AR, LA, MS, NC, TN, and VA
    • 2017: AL, AR, DE, GA, IL, IN, LA, MI, MS, NC, OH, OK, SC, TN, TX, VA, and WI
    • 2018 and 2019: AL, AR, DE, GA, IL, KY, LA, MI, MS, NC, OH, OK, SC, TN, TX, VA, and WI
  • Selecting regional or country-wide geographies will return results containing only the data from states and years that estimates are available for.
  • Because data was obtained from differing sources, discrepancies among years and locations may exist that cannot be accounted for.
  • Certain insect pests injure soybean plants in multiple ways. In this loss calculator, insect pests were placed into the category matching their primary feeding or injury activity. For example, bean leaf beetle adults feed on foliage and fruit while larvae feed on roots; however, bean leaf beetle was placed in the “Defoliators and fruit feeders” category. Likewise, stink bugs were placed in the “Defoliators and fruit feeders” category due to injury to pods and developing seeds, even though they feed by consuming plant sap.
  • Losses caused by “Other insects” are included in the “Defoliators and fruit feeders” category.

This information is only a guide. The values in this resoure are not intended to be exact values of yield losses due to diseases or insect pests, and some data are missing for certain years and locations. Contributors and data managers used the most appropriate means available to estimate disease and insect pest losses and assume no liability resulting from the use of these estimates.
