A survey for root-knot nematodes (Meloidogyne spp.) was undertaken in the central and western parts of Ethiopia during the 1998-2000 cropping seasons. Eight hundred twenty eight samples were collected from different vegetable crops during both the rainy and off-seasons. The major crops grown in the areas are tomato, pepper and onion while other vegetables assessed included snap bean, cabbage, beetroot, carrot and potato. Three root-knot nematode species namely Meloidogyne incognita, M. Javanica and M. Ethiopica were found. Out of 192 field samples in all vegetables, 119 (62%) were found to be infested with Meloidogyne species. M. Incognita was the dominant species with total incidence of 55.3% and 57.7% in 1998-99 and 1999-2000 season next to M. incognita with an incidence of 32.7%. Pepper and tomato were the most seriously affected crops and should receive precedence in future research endeavors.
