This book contains full descriptions of all the root-lesion or meadow nematodes, burrowing nematodes, rice root nematodes and false root-knot nematodes reported from everywhere in the world that were considered by Decraemer & Hunt (2006) to belong to the family Pratylenchidae, order Tylenchida. It also contains the subfamily Nacobboderinae belonging to the family Meloidogynidae. All these nematodes are obligate plant-parasitic nematodes, most of them showing a migratory, endoparasitic way of life but some are sedentary root-gall inciting parasites. This book is amply illustrated with line drawings and some SEM-photographs that are based on microscopic and sub-microscopic observations.
