Abstract. Moringa (Moringa oleifera Lam.) is a crop that becoming more and more important in Niger, but very little attention gas been devoted to its pest problems. Nematode fauna survey was undertaken in three important Moringa producing sites in western Niger. Soil and root samples where taken from the plant’s rhizosphere at 20-30 cm deep. Nematological analysis of these samples revealed the presence of 11 genera of plant-parasitic nematodes among which the most frequent and abundant where Meloidogyne spp., helicothylencus spp. and Hoplolaimus spp. The average prominence values of these three nematodes where 236.69, 105.25 and 97.93 respectively. In roots, Meloidogyne spp. alone represented up to 90% of the plant-parasitic nematode communities. Its average prominent value was 591.46.
Keywords. Moringa oleifera, vegetable crop, plant-parasitic nematodes, Niger
