Ticks transmit a greater variety of pathogenic agents than any other arthropod group, even mosquitoes. In humans, the diseases caused by these agents include Lyme disease, Rocky Mountain spotted fever, human granulocytic anaplasmosis, human monocytic ehrlichiosis, tularemia, Colorado Tick Fever, tick-borne encephalitis, and many others. Th e illnesses involve tens of thousands of cases every year. In domestic animals, the numerous tick-borne disease agents cost the livestock industry billions of dollars. Moreover, many of these diseases have emerged (or re-emerged) within the past 2 or 3 decades (e.g., Lyme disease, human granulocytic anaplasmosis, and others). Despite the use of modern medical and veterinary treatments, the widespread use of pesticides, and sophisticated novel methods for their control, ticks continue to fl ourish. Clearly, detailed and up-to-date knowledge of tick biology and the diseases ticks transmit must be included in medical and veterinary school programs, in the curricula of advanced undergraduate and graduate programs in the biological sciences, and in public health curricula. Th ere is an unquestioned need for a single comprehensive, authoritative, and up-to-date book on the biology of ticks and tick-borne diseases. Th e fi rst edition of the 2-volume Biology of Ticks , published in 1991 and 1993, was written to address this need. However, more than 20 years have elapsed since its publication. Th e fi rst edition met with widespread success, so much so that it is now out of print. In the meantime, numerous scientists, physicians, veterinarians, and other professionals have contacted us to urge the creation of a second edition of Biology of Ticks . However, other treatises on ticks and tick-borne diseases have been published in recent years, especially (1) Ticks: Biology, Disease and Control (2008), A. S. Bowman and P. A. Nuttall (Eds.), published by Cambridge University Press, and (2) Tick-borne Diseases of Humans (2005), J. L. Goodman, D. T. Dennis, and D. E. Sonenshine (Eds.), published by ASM Press. Although there are many excellent chapters on tick biology and diseases, these works are not and never were intended to be fully comprehensive. Many modern aspects of tick biology, such as molecular systematics; tick genetics and genomics; or the molecular basis of blood feeding, digestion, development, reproduction, and innate immune responses, as well as many other aspects of tick biology, ecology, and control, are missing or covered only briefl y.
