A manual of acarology.

In the thirty years since the last edition of this indispensable reference work was published, acarologists have discovered a multitude of new taxa, made major modifications in classification of acarines, and profoundly altered their understanding of the Acari. Now the completely revised and updated third edition is available to researchers, teachers, students, and plant and animal scientists wishing to explore the complex and often astonishing world of mites.
