Technical Abstract: Several species of sap-sucking, chewing, boring, and soil insects attack barley. The most economical and environmentally safe pest control measure is the production and use of barley cultivars with genetic resistance. The authors have highlighted the establishment and use of the USDA-ARS National Small Grains Collection in developing insect resistance in barley germplasm. This collection, among other national and international collections, has a rich history of providing valuable new sources of resistance to various insect pests of barley. Standardized screening assays have been developed to identify and characterize barley germplasm accessions with resistance to several aphid species, as well as the cereal leaf beetle, Hessian fly, and grasshoppers. The germplasm collection has proved to be an invaluable source of resistance genes for these pests, especially the Russian wheat aphid and greenbug. Several resistance genes for each of the target pests have been identified within Hordeum vulgare and have subsequently been made available to the barley breeding community in the form of improved germplasm releases.
