Occurrence of Globodera pallida in Hungary

Golden potato cyst nematode, Globodera rostochiensis , has been known to occur in Hungarian potato fields for more than 20 years. The Hungarian NPPO has been carrying out a country-wide Globodera monitoring programme since 1995 and has inspected 16 000 samples. Until 2000, all records were of G. rostochiensis . However, in 2001, three localities in Pest county were found to be infested with Globodera pallida . This was the first official record of G. pallida in Hungary. The two species have been found together in five fields. Unmixed populations of G. pallida have not been found. Identification was based on morphometric data, as well as on biochemical methods (ELISA technique).
