This book is a n exploration of what we mean when we say that an animal is 'hungry'; it analyzes the concepts of motivation and drive as tested in extensive and elegant experiments on blowflies. The fly, then, is incidental; concepts and experimental techniques for evaluating them are the main subject.
Few creatures are as universally despised as flies. Blamed for pestilence and plagues, they were publicly excommunicated from the medieval church. Beelzebub, “the lord of the flies,” was said to be the embodiment of evil, and, for centuries, flies were considered the result of spontaneous generation—the unnatural consequence of rotting meat. Fly explores the history of this much-maligned creature and then turns to examine its newfound redemption through science. The secrets of the fly’s versatile powers of flight, Steven Connor reveals, are only beginning to be understood and appreciated. Its eyes and wings, for instance, have evolved so perfectly that they provide inspiration for some of today’s most daring technological and scientific innovations. And the humble fruit fly, Connor demonstrates, stands at the center of revolutionary advances in genetic research. Connor delights in tracking his lowly subject through myth, literature, poetry, painting, film, and biology. Humans live in close and intimate quarters with flies, but Fly is the first book to give these common creatures their due.
Originally published in 1985, this book was an attempt at a comprehensive review of the psychology of action in various areas of psychology. It is also an attempt to bridge two languages and traditions in psychology: German and Anglo-American. Although Anglo-American psychology had had an enormous influence on German psychology, the influence had not gone the other way around – at least not in recent years. Therefore, this book attempts to get the two traditions to speak with each other. The main article, from one language area, and the following discussion, from the other language area, together result in an extensive treatment of an action-theoretic approach in the respective psychological area; thus, both the main article and "discussion" should be read together.
The topic of animal motivation deals with how and why animals engage in particular activities: what mechanisms inside the animal generate behaviour, how stimuli from the external environment in fluence these mechanisms, and how this behaviour is beneficial to the animal. The topic is thus central both to academic studies in psychology and zoology and to applied matters in domestic species. Motivation has not been an area of great emphasis in the past 10-15 years but there is now a growing realization that it should receive greater attention. Drawing on concepts and observations from a number of areas, this book provides an overview of the motiva tional processes which determine the choices, timing, and sequencing which are characteristic of animal behaviour. Data and theory from ethology, psychology, and evolutionary biology are synthesized into a contemporary framework for analysing such central features of behaviour as persistence in activities and goal orientation. Principles of motivational analysis are discussed and illustrated with specific case studies. The successive chapters deal with ethological, phy siological, and ecological approaches involving experimental work on a diversity of vertebrate and invertebrate species. Ethological topics include the interaction of external stimuli and internal states, mechanisms of choice, quantitative models of motivation, conflict between tendencies for different activities, and behavioural homeos tasis. The review of physiological research focuses on hunger, the activating roles of nerves and hormones, and the examination of animals with small nervous systems.
As we follow the path of a giant water bug or peer over the wing of a gypsy moth, we glimpse our world anew, at once shrunk and magnified. Owing to their size alone, insects’ experience of the world is radically different from ours. Air to them is as viscous as water to us. The predicament of size, along with the dizzying diversity of insects and their status as arguably the most successful organisms on earth, have inspired passion and eloquence in some of the world’s most innovative scientists. A World of Insects showcases classic works on insect behavior, physiology, and ecology published over half a century by Harvard University Press. James Costa, Vincent Dethier, Thomas Eisner, Lee Goff, Bernd Heinrich, Bert Hölldobler, Kenneth Roeder, Andrew Ross, Thomas Seeley, Karl von Frisch, Gilbert Waldbauer, E. O. Wilson, and Mark Winston—each writer, in his unique voice, paints a close-up portrait of the ways insects explore their environment, outmaneuver their enemies, mate, and care for kin. Selected by two world-class entomologists, these essays offer compelling descriptions of insect cooperation and warfare, the search for ancient insect DNA in amber, and the energy economics of hot-blooded insects. They also discuss the impact—for good and ill—of insects on our food supply, their role in crime scene investigation, and the popular fascination with pheromones, killer bees, and fire ants. Each entry begins with commentary on the authors, their topics, and the latest research in the field.
This second volume of Flies and Disease spans the recorded history of synanthropic flies, from earliest Sumerian writings to contemporary research on their biology and involvement in the transmission of disease agents. Geographically, its coverage is worldwide. Biologically, it provides an in-depth view of the community in the fly and the fly in the community. The exhaustive evaluation of fly involvement in more than sixty human and animal diseases is drawn against a background that gives careful balance to other modes of dissemination. The opening chapter is a survey of attitudes toward flies through recorded history. The second chapter deals with the life history, breeding, distribution, dispersal, and overwintering habits of common synanthropic flies. Chapter 3 looks at the fly as a host and examines its micro-ecology from the viewpoint of the microbe intent on colonizing the fly. The final two chapters examine the evidence for the specific involvement of flies in human and animal diseases. The result is the most complete portrait ever drawn of these ancient pests and a rational basis for new programs of research. This book should prove invaluable to the public health worker, epidemiologist, medical entomologist, microbiologist, and parasitologist. Together with Volume I, it is a monumental work on the complex subject of flics and disease and will remain the definitive work for years to come.

The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
