Japanese beetles have become the primary insect defoliator of soybeans in Illinois over the past several years, but guidelines for their management are outdated. The relationship between defoliation caused by Japanese beetles and components of soybean yield need to be explored to improve decision making for modern soybean production. One of the limitations of making decisions about management of Japanese beetles is a lack of knowledge about the spatial and temporal distributions of Japanese beetles during critical times of soybean development. For example, it is widely reported that Japanese beetles are frequently concentrated along field edges. Because Japanese beetles are so mobile and...
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
