Aphelenchoides arachidis Bos, 1977
A. arachidis was found in Arachis hypogagea L. ( Fabaceae Lindl.) (Minton & Baujard 1990) as an endoparasite of groundnut testa in Nigeria (Bos 1977a) and more recently in Egypt and South Africa (Montasser et al. 2008, Lesufi et al. 2015). Although the symptoms have only been described on Arachis, roots of some Poaceae Barnhart species ( Oryza sativa L., Saccharum officinarum L., Sorghum sp., Pennisetum glaucum (L.) R. Br. and Zea mays L.) had high quantities of this species and were reported as hosts (Bos 1977b, CABI 2010, Escuer & Bello 2000). This nematode was also found on roots of non-specified wild grasses (Bos 1977b, CABI 2010). According to Bos (1977b) two biotypes, one on cereals and the other on cereals and groundnuts, may be occurring in fields.
