TY - JA AU - Rochow,W.F. TI - The role of aphids in vector specificity of barley yellow dwarf virus SN - 0032-0811 PY - 1958/// CY - Washington, D.C. (USA) PB - Bureau of Plant Industry KW - AGROVOC KW - Aphidoidea KW - Barley yellow dwarf luteovirus KW - Vectors N2 - Colonies of aphids from New York and from Washington were compared as vectores of live "vector specific" isolates of barley yellow dwarf virus. Tests involved acquisition feeding on detached halfleaves or the rearing of aphids on virus source plants. Virus transmission by apple grain aphids regularly used in New York and by apple grain aphids from Washington was identical in all but 1 of 16 comparisions. Virus transmission by English grain aphids from the two areas was identical in all but 3 of 20 test. These data are considered as evidence that the basis for the observed vector specificity of barley yellow dwarf virus rests with the virus and not with the vector T2 - Plant Disease Reporter ER -
