The presence of nematodes was evaluated in the skin and underlying parenchyma of several varieties of Andean tubers (Andean potato, ‘Oca’ and ‘Papalisa’) from Argentina and Bolivia. Nacobbus aberrans was widely distributed in the Andean region. Other phytophagous nematodes detected were Meloidogyne incognita, M. javanica, Globodera sp. and Pratylenchus sp. Two different species of the Family Anguinidae, Hexatylus sp. and Aphelenchus avenae, were also found. Furthermore, results of two different methods usually used to evaluate tuber sanitation were analyzed: processing of skin and underlying parenchyma and closed bag bioassays, the former appearing as the most efficient.
