Aphelenchoides fragariae (Ritzema Bos, 1890) Christie, 1932

The most striking augmentation in the number of reported plant associations of Aphelenchoides spp. belongs to A. fragariae . Escuer & Bello (2000) and Fu (2012) quote Siddiqi (1975) and mention 250 plant species belonging to 47 families, but as shown in Table 1 and Fig. 1, at least 621 plant species and varieties from 287 genera are associated with A. fragariae, most of them (84%) within flowering plants. A. fragariae is also the species that is reported on the highest number of ferns followed by A. ritzemabosi and A. besseyi, 162, 7 and 4 species respectively (Fig. 1). To date, it is also the only Aphelenchoides species reported on Marchantiophyta (Kohl 2008). Several hosts are shared with other Aphelenchoides species (Fig. 2).
