These viruses are classified in the Bromoviridae family, genus Ilarvirus (ApMV) or Secoviridae family, genus Nepovirus (ArMV).
Species of Xiphinema in addition to the direct root damage caused by their feeding also are known to transmit viral diseases like tomato ring spot nepovirus (Tom RSV), tobacco ringspot nepovirus (Tob RSV) that infects tomato, tobacco, and soybean and has an economically important impact on cucurbits (Fulton, 1962; Imle and Samson, 1937; Brown et al., 1993, 1995).
Este metodo de inoculacion viral a diferencia de los otros, ha reportado eficiencias hasta del 100% (Aebig et al., 2005), ha sido utilizado con exito no solo para inocular Begomovirus (Hernandez et al., 2001; Morilla et al., 2005; Ariyo et al., 2006), sino tambien Potyvirus (Gal-On et al., 1995; 1997), Luteovirus (Yamagishi et al., 2006), Nepovirus (Valat et al., 2003), Cucumovirus (Aebig et al., 2005), Polerovirus (Hoffmann et al., 2001), entre otros.
A nivel mundial, se han identificado doce virus que infectan este cultivo, pertenecientes a los grupos Nepovirus, Potyvirus, Carlavirus, Comovirus, Geminivirus y Caulimovirus (Brunt et al., 1996).

One of the most serious problem is grapevine fanleaf nepovirus, transmitted by Xiphinema index.
En Colombia, las investigaciones sobre enfermedades virales que afectan el cultivo de tomate han sido realizadas por medio de tecnicas microscopicas, serologicas y/o moleculares, identificando a la fecha virus pertenecientes a los generos: Begomovirus, (Tomato yellow mosaic virus--ToYMV), Tobamovirus (Tobacco mosaic virus--TMV y/o Tomato mosaic virus--ToMV), Cucumovirus (Cucumber mosaic virus--CMV), Tospovirus (Tomato spotted wilt virus--TSWV, Impatients necrotic spot virus--INSV), Crinivirus (Potato yellow vein virus--PYVV), Potyvirus (Pepper deforming mosaic virus--PepDMV) y Nepovirus, (Tobacco ringspot virus--TRSV) (Tamayo y Jaramillo, 2006; Uribe-Echeverri, et al.
Species of Xiphinema inaddition to the direct root damage caused by their feeding also are known to transmit viral diseases like tomato ringspot nepovirus (TomRSV), tobacco ringspot nepovirus (TobRSV) that infects tomato, tobacco, and soybean and has an economically important impact on cucurbits (Fulton, 1962; Imle and Samson, 1937; Brown et al., 1993, 1995).
