Fundamentals of Plant-Parasitic Nematode Diagnostics, Systematics and Classification offers a comprehensive and authoritative resource for researchers, students, and professionals engaged in nematode biosystematics. Their microscopic size, morphological plasticity, and broad ecological diversity have long complicated efforts to accurately identify nematode species and reconstruct their evolutionary relationships. Unlike many other animal groups, the full extent of nematode species richness remains largely unknown, and aside from rare fossilized specimens preserved in amber, paleontological evidence is minimal.
This book confronts these challenges by integrating recent advances in molecular systematics with traditional taxonomic frameworks to build a unified reference dataset. It critically surveys historical classification models and establishes a solid foundation for advancing research on nematode evolution and identification. Rather than concentrating on isolated taxa, it presents a broad conceptual toolkit—encompassing diagnostic techniques, hierarchical organization, and evolutionary analysis—that directly supports the management of character data and the development of robust taxonomic publications. With its interdisciplinary scope and emphasis on both theory and practical diagnostics, this book is posed to become an essential reference for those working in agriculture, plant science, and nematology.

He joined the Department of Crop Protection at the Centre for Agricultural Research and Formation in Granada from the regional government of Andalusia in 1989. In 1990 he was recipient of the Phytopathological Research Award ‘Antonio Ciccarone’, from the Mediterranean Phytopathological Union, and in 1992 moved to Córdoba (Spain) to the Department of Crop Protection at the Institute for Sustainable Agriculture belonging to the Spanish Council for Scientific Research, where he is now a research scientist. Castillo’s research has focused primarily on plant-nematode and nematode-soilborne fungi interactions, as well as diagnosis of nematode diseases, host-parasite relationships and nematode control by means of strategies compatible with sustainable agriculture. He has produced more than 280 peer reviewed research articles and co-authored several comprehensive monographs of the plant-parasitic nematode genera Rotylenchus, Pratylenchus and Meloidogyne.
