Host immune responses to ectoparasitic arthropods are critical elements in determining the nature of animal host-arthropod relationships, including transmission of vector-borne pathogens. This is the first book to provide a comprehensive analysis for both the student and specialist of the emerging field of “immunoentomology”. Our fundamental understanding of this topic has increased dramatically in recent years. Chapters prepared by specialists from the USA, UK and Australia provide comprehensive reviews of key subjects. The book concludes with a consideration of the application of fundamental knowledge about the immunology of the host-arthropod interface to the development of anti-arthropod vaccines. It is aimed particularly at medical and veterinary entomologists and acarologists, as well as immunologists.
