Natural infectivity of migrating aphid vectors of barley yellow dwarf virus in Northern Italy - 1990 - Printed

13 ref

The infectivity of winged migrating aphid vectors of barley yellow dwarf virus (BYDV) was investigated from 1981 to 1986 in two localities in northwestern and northeastern Italy (Carmagnola, Turin, and Pozzuolo, Udine) by using two types of suction traps that capture live aphids. Flying aphids were captured, identified, and tested individually for bydv transmission on either barley or oats, which were then checked for virus presence by both observation of symptoms and ELISA. Of nine aphid species collected near Turin, five transmitted BYDV to the indicator plants, namely: Anoecia corni (Fabricius), Rhopalosiphum insertum (Walker), R. maidis (Fitch), R.
