The presence of other delphacid species in areas infected with this vi- rus suggests that those species could have a function in the epidemiology of di- sease. Pyrophagus tigrinus was first found by chance in 1997 in Jesús María (Cór- doba) in triticale crops affected by MRCV. The aim of this work was to demons- trate the capacity of P. tigrinus to transmit the MRCV to triticale under experimental conditions. The culture of P. tigrinus under controlled conditions was initiated and

Typical witches′-broom symptoms were observed in diseased alfalfa plants from fields of the ‘Cuyo’ region in the Andean midwest. Pleomorphic bodies were observed by electron microscopy in sieve tubes of the diseased plants. The results obtained from the sequence homology, similarity coefficients derived
