This book contains full descriptions of all the stunt, sting and awl nematodes (433 species) reported from everywhere in the world that were considered by Decraemer & Hunt (2006) to belong to the family Dolichodoridae, order Tylenchida. It is amply illustrated with line drawings and some SEM photographs that are based on microscopic and sub-microscopic observations. They are obligate plant parasites living in the soil and so they have an economic importance.
