The current book takes a unique integrated approach combining both ectoparasite biology and veterinary dermatology. As to the latter concept, ectoparasitic infestations of domestic animals have overt clinical consequences requiring a distinct approach for diagnosis and treatment. Thus, the diagnostic techniques of skin disorders in domestic animals have been presented here. Since the book is directed primarily at the non-entomologists, to improve its logical structure and comprehensibility, it has been deemed appropriate to abridge some of the more involved entomological databases, particularly in relation to arthropod classification and phylogenetics and ecology of arthropod ectoparasites. The book aims to introduce the phylogeny, ecology, biology, epidemiology, dermatology, pathology, diagnosis, and control of arthropod ectoparasites of domestic animals. In addition, a brief morphological description of these parasites is also presented. This book is of importance for the students and practitioners of veterinary medicine, animal husbandry, and applied animal sciences.
