Globodera pallida is a species of nematode in the family Heteroderidae. It is well known as a plant pathogen, especially of potatoes. It is one of the most economically important plant parasitic nematodes, causing major crop losses, and is a model organism used to study the biology of cyst nematodes. (Wikipedia, 2024.

Globodera rostochiensis, commonly known as the golden nematode, golden eelworm or yellow potato cyst nematode, is a plant pathogenic nematode.
