Description A host suitability study of the important and widely distributed species (Scutellonema clathricaudatum, Xiphinema parasetariae, Tylenchorhynchus spp. and Paralongidorus bullatus) was conducted in the Sahelian zone of West Africa. Thirteen crop species: bamabara groundnut (Voandzeia subterranea), cowpea (Vigna unguiculata), groundnut (Arachis hypogaea), maize (Zea mays), pearl millet (Pennisetum glaucum), pigeonpea (Cajanus cajan), sesame (Sesamum indicum), sorghum (Sorghum bicolor), stylo (Stylosanthes fruticosa, S. hamata), sunflower (Helianthus annuus), Vigna aconitifolia and Vigna radiata. All the plant species tested were host of S. clathricaudatum; pearl millet was an excellent host whereas sorghum and Stylosanthes hamata were poor hosts. Based on the nematode densities in soil at harvest, sorghum and maize were the two preferred hosts of Tylenchorhynchus. Populations of Xiphinema parasetariae were greatest on sesame and pigeonpea. Stylosanthes spp. had the lowest infestation by this species and were poor hosts. Paralongidorus bullatus populations increased on pearl millet, groundnut, cowpea, sunflower, bambara groundnut, pigeonpea, maize and sesame. The total number of plant parasitic nematodes at harvest was greatest in plots planted to pigeonpea. Maize was another crop conducive to increase in their populations. S. hamata was the least suitable crop for reproduction of the identified plant parasitic nematodes.
