Résumé:

Foliar nematodes represent a minor feeding group within the genus Aphelenchoides Fischer, 1894. The facultative plant parasitic species A. blastophthorus can cause crinkling of leaves, reduced vigor, and stunting of agricultural and ornamental plants. Here we report the first finding of A. blastophthorus in leaves, crowns, and roots of strawberry plants collected in Switzerland in 2018. Species identification was confirmed by morphological and morphometric characterization supported by molecular barcoding of 18S ribosomal RNA (18S), 28S ribosomal RNA (28S), and cytochrome c oxidase I (COI) gene fragment analyses. Phylogenetic analysis of 18S indicated that A. blastophthorus was grouped within close distance to A. fragariae, a well-known foliar nematode affecting strawberry plants. Furthermore, the newly generated molecular barcodes of the partial 28S and COI of A. blastophthorus will support species identification in the future.
