“…Unfortunately, grapes have been susceptible to various pathogens, among them the dagger nematode, Xiphinema index (Hewitt et al 1958). This migratory ectoparasitic nematode is considered a major pest in grape-growing countries in Mediterranean environments and temperate climates where grapevine grows (Hao et al 2012;M'rabet Samaali et al 2022). Xiphinema index is a nematode vector of nepovirus Grapevine fanleaf virus (GFLV), which is the causal agent of grapevine fanleaf degeneration disease (Belin et al 2001;Hewitt et al 1958).…”

Grapevine fanleaf virus (GFLV) is one of the most severe virus diseases of grapevines, causing fanleaf degeneration that is transmitted by Xiphinema index. This paper aims to isolate Xiphinema species from Tunisian vineyard soil samples and assess their ability to acquire and transmit GFLV under natural and controlled conditions. Based on morphological and morphometric analyses, Tunisian dagger nematodes were identified as X. index and Xiphinema italiae. These results were confirmed with molecular identification tools using species-specific polymerase chain reaction primers. The total RNA of GFLV was extracted from specimens of Xiphinema and amplified based on real-time polymerase chain reaction using virus-specific primers. Our results showed that X. index could acquire and transmit the viral particles of GFLV. This nepovirus was not detected in X. italiae, under natural conditions; however, under controlled conditions, this nematode was able to successfully acquire and transmit the viral particles of GFLV.
