Brief Project Summary:

Damage severity of the soybean stem borer has in Kansas counties but management strategies remain limited. RNAi gene silencing in soybean stem borer larvae is a new viable way to create borer-resistant plants, and promising results of previous experiments suggest this may be possible. Results demonstrate that adult colonization patterns vary between fields and through time and need to be better predicted. Objectives of this project include creating soybeans resistant by inserting borer RNA into the plants to interfere with genes necessary for borer survival; and improve insecticide efficacy by using host plant and other environmental conditions to adjust application timing and placement.

We continue to seek workable solutions to reduce yield losses from the current major soybean insect pests in Kansas: the soybean stem borer, which causes stem lodging; and the soybean pod worm, which feeds on leaves and pods. Insecticides and conventional genes for insect resistance are not feasible for borer control, so we are continuing to develop a transgenic technique that kills larvae. Many factors affect the efficacy of insecticides that control soybean pod borer. Experiments continue to determine factors that promote the severity of podworm damage in the field ignorer to avoid yield losses.

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.
