In 2021, during a survey in the Djelfa region of Algeria, the dagger nematodes Xiphinema index and Xiphinema pachtaicum were found infesting grapevine (Vitis vinifera). These nematodes were identified based on their morphological/morphometric features and then confirmed via molecular analysis of the D2D3 region (26S rRNA). Microscopic assessment of females indicated the occurrence of both X. index and X. pachtaicum on the grapevine. The 28S D2D3 sequences shared more than 98.82% sequence similarity with GenBank references for X. pachtaicum and X. index. To our knowledge, this is the first report of X. index and X. pachtaicum infecting grapevine in Algeria.
En 2021, durante un estudio en la región de Djelfa en Argelia, se encontraron las especies de nematodos daga Xiphinema index y Xiphinema pachtaicum infestando la vid (Vitis vinifera). Las poblaciones de nematodos daga se identificaron en función de sus características morfológicas/morfométricas y luego se confirmaron mediante análisis molecular de la región D2D3 (ARNr 26S). La evaluación microscópica de las hembras indicó la presencia tanto de X. index como de X. pachtaicum en la vid. Las secuencias de 28S D2D3 compartían más del 98.82% de similitud de secuencia con las referencias de GenBank para las dos especies X. pachtaicum y X. index. Hasta donde sabemos, este es el primer informe de X. index y X. pachtaicum que infectan la vid en Argelia.
