This book is designed primarily as a textbook for graduate and postgraduate courses in Medical, Public Health and Veterinary Entomology. Its uniqueness is that its emphasis is on disease as opposed to arthropods. It includes general discussions of epidemiology, transmission, disease control, vector control and disease surveillance. In addition, it contains chapters oriented towards the many specific arthropod-borne diseases. Furthermore, the book discusses the many direct impacts that parasitic insects have on human and animal health. The arthropods themselves are dealt with in two introductory chapters.

From economics and business to the biological sciences to physics and engineering, professionals successfully use the powerful mathematical tool of optimal control to make management and strategy decisions. Optimal Control Applied to Biological Models thoroughly develops the mathematical aspects of optimal control theory and provides insight into t

This book may be regarded as consisting of two parts. In Chapters I-IV we pre sent what we regard as essential topics in an introduction to deterministic optimal control theory. This material has been used by the authors for one semester graduate-level courses at Brown University and the University of Kentucky. The simplest problem in calculus of variations is taken as the point of departure, in Chapter I. Chapters II, III, and IV deal with necessary conditions for an opti mum, existence and regularity theorems for optimal controls, and the method of dynamic programming. The beginning reader may find it useful first to learn the main results, corollaries, and examples. These tend to be found in the earlier parts of each chapter. We have deliberately postponed some difficult technical proofs to later parts of these chapters. In the second part of the book we give an introduction to stochastic optimal control for Markov diffusion processes. Our treatment follows the dynamic pro gramming method, and depends on the intimate relationship between second order partial differential equations of parabolic type and stochastic differential equations. This relationship is reviewed in Chapter V, which may be read inde pendently of Chapters I-IV. Chapter VI is based to a considerable extent on the authors' work in stochastic control since 1961. It also includes two other topics important for applications, namely, the solution to the stochastic linear regulator and the separation principle.

Diptera, or true flies, are of considerable economic importance, as these flies have a valuable role as scavengers, parasitoids and predators of other insects, pollinators, food for predators, bio-indicators of water quality, and tools for scientific research. In nine chapters, this book examines various aspects of flies of the order Diptera as well as some types of mosquitos and midges. Topics covered include taxonomy, phylogeny, life cycle, feeding habits, population control strategies, and more. A unique chapter on forensic entomology is particularly interesting. Beautifully illustrated and expertly researched, this volume will appeal to entomologists, biologists, and naturalists.

The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]

This book provides examples of the most likely pests and diseases affecting man and animals in Europe, with emphasis on ecological factors favouring these diseases and methods for prevention and intervention.

This guideline defines ventilation and then natural ventilation. It explores the design requirements for natural ventilation in the context of infection control, describing the basic principles of design, construction, operation and maintenance for an effective natural ventilation system to control infection in health-care settings.
