Technical Abstract: Soybeans [Glycine max] are the second largest cash crop in US Agriculture, but the soybean yield is compromised by infections from Heterodera glycines, also known as Soybean Cyst Nematodes [SCN]. SCN are the most devastating pathogen or plant disease soybean producers confront. This obligate parasite requires nutrients from the plant to complete its life cycle. To date, SCN nutritional requirements have not been clearly defined. Growth media which are currently used to support SCN growth contain soy products. Understanding the SCN nutritional requirements and how host plants meet those requirements should help lead to the control of SCN infestations. The nutritional requirements of SCN are reviewed in this chapter and are compared to those of other nematode species. Carbohydrates, vitamins, amino acids, lipids, and other nutritional requirements are discussed. Survival of parasitic nematodes requires adequate nutritional sources. Essential nutrients are at least partially supplied by the host. But, availability of nutrients may not alone be sufficient for survival and reproduction. The parasite must also be able to establish a feeding site. Both the establishment of the feeding site and the presence of adequate nutrients for the soybean cyst nematode [SCN] are discussed.
