Book Description
There are more than 36,000 described species in the family Cerambycidae in the world. With the significant increase of international trade in the recent decades, many cerambycid species have become major plant pests outside their natural distribution range, causing serious environmental problems at great cost. Cerambycid pests of field, vine, and tree crops and of forest and urban trees cost billions of dollars in production losses, damage to landscapes, and management expenditures worldwide. Cerambycidae of the World: Biology and Pest Management is the first comprehensive text dealing with all aspects of cerambycid beetles in a global context. It presents our current knowledge on the biology, classification, ecology, plant disease transmission, and biological, cultural, and chemical control tactics including biosecurity measures from across the world. Written by a team of global experts, this book provides an entrance to the scientific literature on Cerambycidae for scientists in research institutions, primary industries, and universities, and will serve as an essential reference for agricultural and quarantine professionals in governmental departments throughout the world.

Book Description
JOHN G. HILDEBRAND Research on insect olfaction is important for at least two reasons. First, the olfactory systems of insects and their arthropod kin are experi mentally favourable models for studies aimed at learning about general principles of olfaction that apply to vertebrates and invertebrates alike. Detailed comparisons between the olfactory pathways in vertebrates and insects have revealed striking similarities of functional organisation, physiol ogy, and development, suggesting that olfactory information is processed through neural mechanisms more similar than different in these evolution arily remote creatures. Second, insect olfaction itself is important because of the economic and medical impact of insects that are agricultural pests and disease vectors, as well as positive impact of beneficial species, such as the bees and moths responsible for pollination and production of honey. The harm or benefit attributable to an insect is a function of what it does - that is, of its behaviour - which is shaped by sensory information. Often olfaction is the key modality for control of basic insect behaviour, such as ori entation and movement toward, and interactions with, potential mates, appro priate sites for oviposition, and sources of food. Not surprisingly, therefore, much work on insect olfaction has been motivated by long-term hopes of using knowledge of this pivotal sensory system to design strategies for mon itoring and managing harmful species and fostering the welfare of beneficial ones.

Book Description
During his lifetime, W.E. Blatz was so much occupied with the development of the University of Toronto’s Institute of Child Study that he was able to devote little time to writing. This is his first book to appear in twenty-one years, and his first complete exposition of his famous Theory of Security. The Theory of Security is radically different from the theories promulgated by Freudian psychologists. Whereas Freudian personality theory is based on the notion of “unconscious,” an entity that is only indirectly observable, the Theory of Security derives from the observation of the conscious state in all its manifestations. Dr. Blatz thus makes use of both empirical observations and the results of introspection, and, as might be expected, some of his conclusions run counter to those reached in much current psychological discussion. But proof of the forcible influence of the theory and its author may be found in the impressive number of books and articles already published by Dr. Blatz’s associates at the Institute of Child Study, applying the theory to the practical problems of psychological observation and therapy. It is fitting that the man whose work has generated so much fruitful research by others in this field should at last have set down in book form the fundamental principles that guided them.
