Acquisition Through Artificial Membranes and Transmission of Oat Blue Dwarf Virus by Macrosteles fascifrons. Donna L. Long, Graduate Research Assistant, Plant Pathology Department, North Dakota State University, Fargo 58102; R. G. Timian, Research Plant Pathologist, Plant Science Research Division, USDA, North Dakota State University, Fargo 58102. Phytopathology 61:1230-1232. Accepted for publication 19 May 1971.

Oat blue dwarf virus (OBDV) was transmitted by Macrosteles fascifrons (aster leafhopper) after an acquisition feeding on clarified plant sap through Parafilm M membranes. Transmission was successful only if the plant sap was refrigerated during feeding. OBDV acquisition and transmission through membranes was slightly less efficient than acquisition and transmission from infected plants.
