Within weeks of its identification in the United States in 1986, the aphid was found in the five states and across several million hectares. D. noxia is reported to vector several small grain viruses including brome mosaic virus (BMV) and barley yellow dwarf virus (BYDV). Nonpersistent and persistent modes of transmission were tested with a Texas clone of D. noxia and a Nebraska isolate of BMV on Baart wheat (Triticum aestivum L.) and Henry barley (Hordeum vulgare L.). No symptoms were observed on any test seedling following insect feeding. After 28 days the leaf tips T2 - Burnett, P.A. (ed.). World perspectives on barley yellow dwarf. Proceedings.
