"In the thirty years since the second edition of A Manual of Acarology was published, acarologists have discovered a multitude of new mite taxa, made major modifications in acarine classification, and profoundly altered their understanding of this vast group, inspiring new and innovative approaches to resolving many basic and applied acarological problems. Now, this completely revised and updated reference, the most comprehensive and recent in the discipline, is available to researchers, teachers, students, and plant and animal scientists wishing to explore the complex and often astonishing world of mites.
