Survey on Globodera pallida and G. rostochiensis in Algeria
In Algeria, potato cyst nematodes (Globodera pallida and G. rostochiensis, both EPPO A2 List) are known to be present in the regions of Algiers and Aïn Defla (EPPO RS 2017/100). Soil samples from potato (Solanum tuberosum) fields taken between 2013 and 2016 showed that potato cyst nematodes also occur in the southern regions. Globodera pallida occurred predominantly in the northern region (Algiers, Blida, Tipaza and Boumerdès), whereas G. rostochiensis occurred predominantly in the southern regions (El Oued and Bechar). No mixed populations were observed during this study.
