Globodera pallida is absent from Argentina
In 2005, during an inspection of a potato-growing area in North-Western Argentina, cysts belonging to the genus Globodera were detected on Andean potato roots in a field, in the province of Salta (Lax et al., 2005). At that time, the nematode population was identified as Globodera pallida (EPPO A2 List) based on morphological and morphometric characters. This was considered to be the first report of G. pallida in Argentina. However, molecular studies (comparison of ITS-rRNA gene sequences) were conducted and showed that the species found in Salta was not G. pallida but G. ellingtonae (Lux et al., 2014). Therefore, G. pallida is considered as absent from Argentina.
