Migrations of aphid vectors of barley yellow dwarf virus in Northeast and Northwest Italy - 1990 - Printed

8 ref

The flight activity of aphid species known as vectors of barley yellow dwarf virus (BYDV) was studied in the northwest and the northeast of Italy from 1982 to 1986. The winged, migrating forms were captured daily with two Rothamsted Insect survey suction traps positioned at 12.2 m above ground level, at Carmagnola, near Turin, and at Pozzuolo del Friuli, near Udine. Numbers of individuals captured were compared weekly for Rhopalosiphum padi (L.) (the most frequent species) and for all vectors together. Weekly mean temperature and weekly precipitation were recorded for the two localities. During the last 2 years, data so obtained were used to
