CIMMYT. 1990. p. 260-26591-013864Summary: Barley yellow dwarf virus (BYDV) has been causing severe yield losses in autumn-sown cereals in Friuli-Venezia Giulia, northeastern Italy, since 1978. Since 1983, the correlation between migrations of aphid vectors, their natural infectivity, and infection in barley (Hordeum vulgare L.) crops has been studied. An infectivity index was obtained by multiplying the number of the aphids caught in a Rothamsted Insect Survey trap by their infectivity. To evaluate the BYDV incidence in barley fields, one plot of the cv. Astrix was sown in mid-October each year in close proximity to the suction traps. The BYDV presence in both Avena sativa L. test plants and the barley
