A nematological analysis was conducted in the peridermis and underlying parenchyma tissue of different tuber varieties of Andean crops from Argentina and Bolivia. Plant-parasitic nematodes were detected most frequently. Nacobbus aberrans was the most widely distributed in the sampled localities and associated with tubers of numerous potato varieties. Nematodes of other trophic groups were also detected, including bacterial and fungal feeders, insect parasites, predators, and omnivores. Representatives of several trophic categories were detected within the same sample. Tubers were a suitable medium for nematode development and dissemination.
