Última Indigenous and introduced species of the Bemisia tabaci complex in sweet potato crops from Argentina Agriscientia (Córdoba) Alemandri,V; Martino,J.A; Di Feo,L; Truol,G. Sweet potato (Ipomoea batatas (L.) Lam) is one of the most important crops worldwide. Recently, the appearance of severe viral symptoms has been observed in sweet potato crops in the pampas region of Argentina and both begomovirus and crinivirus, exclusively transmitted by whiteflies, have been identified. The aim of this study was to identify B. tabaci species from sweet potato crops in Colonia Caroya by analysing mitochondrial cytochrome c oxidase subunit I (mtCOI) sequences. Two previously described haplotypes were identified: New World2 (indigenous species) and MEAM1 (introduced species). The results indicate the presence of both species, which are potential vectors of begomovirus and crinivirus in Argentina.

In Argentina, wheat fields have exhibited virus-like symptoms, such as chlorotic streaking, dwarfing, yellowing and empty ears since 2007. Symptomatic plants and leaves samples were collected in Marcos Juárez (2007) and Río Cuarto (2008 and 2013), both of them in Córdoba province. The virus was experimentally transmitted from symptomatic wheat plants to wheat cv. Baguette 10 and cv. BioINTA 3005 using the vector Delphacodes kuscheli Fennah (Delphacidae); symptoms of chlorotic streaking, dwarfing and yellowing appeared in the inoculated cereals at 10-15 days post-inoculation. Virus presence was confrmed by electron microscopy and RT-PCR using degenerated primers, which amplified a conserved region of the plant rhabdovirus polymerase (L) gene. Sequence...
