The first chapter gives a detail account of methodology used to extract soil nematodes for taxonomical study. All other chapters provide the diagnostic characters of different orders, suborders, families and subfamilies with their keys according tot he systematic of nematodes species reported from Thar Desert of Rajasthan. From the taxonomical point of view, line diagram of anterior end (fig. 1) and different type of female and male reproductive organs (fig.2) of nematodes of each suborders are provided. Few habitats photograph have also been enclosed in the end of the book.

For instance, a square yard of wood land or agricultural habitat may contain several million nematodes. Many species are highly specialized parasites of vertebrates, including humans, or of insects and other invertebrates. Other kinds are plant parasites, some of which can cause economic damage to cultivated plants. Nematodes are particularly abundant in marine, freshwater and soil habitats. Soil is an excellent habitat for nematodes. Because of their importance to agriculture, much more is known about plant-parasitic nematodes than other kinds of nematodes which are present in soil. Most kinds of soil nematodes do not parasitize plants, but are beneficial in decomposition of organic matter. These nematodes are referred as free-living nematodes.
