Although usually treated as unified subject, in many respects the two components of what is broadly described as 'medical and veterinary is usual, the term entomology is entomology' are clearly distinct. As used loosely here to refer to both insects and arachnids. In medical entomology blood-feeding Diptera are of paramount importance, primarily as vectors of pathogenic disease. Most existing textbooks reflect this bias. However, in veterinary entomology ectoparasites such as the mites, fleas or dipteran agents of myiasis assume far greater prominence and the most important effects of their parasitic activity may be mechanical damage, pruritus, blood loss, myiasis, hypersensitivity and dermatitis, in addition to vector-borne pathogenic disease. Ectoparasite infestation of domestic and companion animals, therefore, has clinical consequences necessitating a distinct approach to diagnosis and control. The aim of this book is to introduce the behaviour, ecology, pathology and control of arthropod ectoparasites of domestic animals to students and practitioners of veterinary medicine, animal husbandry and applied biology. Since the book is directed primarily at the non-entomologist, some simplification of a number of the more involved entomological issues has been deemed necessary to improve the book's logical structure and comprehensibility, and keep its length within limits. A reading list is presented at the end of each chapter to act as a stepping-stone into the specialist literature.

The threat of long-range missile proliferation has been growing since the end of World War II. Today some 28 countries possess long-range missiles and this number is expected soon to grow by one-third. Throughout the Cold War, the U.S. viewed the missile threat in an East-West context. However, beginning with the 1980's Iran-Iraq "War of the Cities" the U.S. view of the missile threat began to change. Third World rogue states such as Iran, Iraq, Libya, and North Korea gained access to long-range missiles and demonstrated a willingness to use them. The proliferation of missiles to these states added to the growing concern over the proliferation of nuclear, biological, and chemical weapons. Together, missiles and unconventional warheads created the potential of rogue states using weapons of mass destruction. In response to these particular problems (and others), the U.S. and its partners in the G-7 announced the formation of the Missile Technology Control Regime (MTCR) in 1987. The purpose of the MTCR was to prevent the proliferation of missiles capable of delivering nuclear weapons.
