Goal: Develop Idaho wheat resistant to wireworms by novel RNA interference technology

Dr. Arash Rashed, Kimberly Andrews, Fangming Xiao

Wireworms are the immature stage of all click beetle species (Coleoptera: Elateridae). In the recent decade, wireworms have been resurging as devastating pests of a wide range of crops in the Pacific Northwest (PNW) region of the United States. Wireworms can stay in the soil for several years (up to 10 years) and infest crops in almost any rotation. Idaho Wheat Commission has funded University of Idaho researchers to study wireworm ecology, management, and the expected yield loss to this pest.

This project was developed to identify vital genes that could negatively impact wireworm survival and confirm the downregulation of those vital genes by injecting the wireworms with laboratory-constructed dsRNA. This information would facilitate developing resistant wheat genotypes, should there be a market for such products.
