🦠 Taxonomy of Plant Parasitic

Taxonomy provides a common framework to identify and classify plant-parasitic nematodes. This lesson summarizes diagnostic characters used in higher-level grouping and practical identification.

---

Basis of Nematode Taxonomy

Taxonomy integrates morphology, anatomy, and increasingly molecular evidence to place nematodes into systematic groups. In practical plant pathology, structural characters remain foundational.

Diagnostic Characters of Major Groups

Classical distinctions between major groups rely on sensory structures, cuticle/body-wall characters, reproductive morphology, and foregut organization.

Consistent use of these characters supports reliable classification in routine diagnosis.

Practical Relevance in Plant Pathology

Accurate taxonomy is essential for predicting host range, pathogenic behavior, and management options. Closely related taxa can differ in biology and control response.
