Depending on the species, nematodes may feed on a variety of organisms, including plants, other nematodes and their eggs, fungi, protozoa, bacteria, tardi-grades, enchytraeids, and insect larvae (Freckman and caswell 1985). Nematodes of the genera Trichodorus and Paratrichodorus range from 0.5 to 1.5 mm long. Nematodes are bilaterally symmetrical, worm-like organisms that are surrounded by a strong, flexible noncellular layer called a cuticle.
