Many people are familiar with animal parasitic nematodes such as Ascaris and Trichinella because they are relatively large and easily visible. Other kinds of nematodes parasitize insects and are used in management of insect pests. Most plant parasitic nematodes however, are not visible with a naked eye and require special equipment and training for their recognition. Plant parasitic nematodes may be categorized based on their feeding behavior and their hosts. Most plant parasitic nematodes feed on root systems of plants while some are able to feed on the above ground parts. Some of the plant parasitic nematodes, e.g., soybean cyst nematode, are important economic pests. Some nematodes can cause significant economic losses without any visible symptoms on the plants. Some nematodes, e.g., root knot nematodes, have broad host ranges and are widespread around the world, whereas others, like soybean cyst nematode, are relatively host specific. In Indiana, soybean cyst nematode is the most important plant parasitic nematode in soybean and needle nematode is the most important nematode in corn.
