Abstract

The morphlogy of a population of Cactodera thornei (Golden et Raski, 1977) Krall et Krall, 1978 found in cereal fields in China is illustrated by light microscope micrographs and drawings. This is the first report of this cyst nematode not known previously to occur in Asia. The morphology and morphometrics of juveniles and cysts of the chinese population correspond with previously published literature. However the range of the cyst length is relatively shorter than in the American population (364-633 µm vs 485-806 µm). There is also a small variation in juvenile stylet length (23.5-26.1 µm vs 25-28 µm) and DGO (2.6-3.9 µm vs 5-7 µm).
