Pyrophagus tigrinus Remes Lenicov & Varela (Hemiptera: Delphacidae), nuevo vector del Mal de Río Cuarto virus (MRCV, Fijivirus) en condiciones experimentales

SUMMARY Mal de Río Cuarto virus (MRCV), causal agent of the most important disease that affects maize in Argentina, is spread under natural conditions by Delphacodes kuscheli. 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
