Abstract

On the occurrence of vectors of barley yellow dwarf virus on various host plants in the Aschersleben area during 1985 to 1987.

Abstract

Results of fortnightly catches of aphids in yellow traps from mid-Jun. to mid-Nov., simultaneous inspection of cereal and grass hosts of BYDV for aphid infestation and serological diagnosis of BYDV infection in these hosts showed Macrosiphum [Sitobion] avenae and Rhopalosiphum maidis to be the most important vectors of BYDV to winter barley in the GDR, and R. padi to be less important. Winter wheat, volunteer winter barley, oats, Echinochloa crus-galli and Festuca pratensis were found to be important aphid and virus reservoirs; maize was of less importance.
