This book uses an interdisciplinary perspective, encompassing the political, social, and economic dimensions of pest problems, as well as their agronomic, ecological and technological features. The authors provide a working manual, including relevant concepts and tools, covering problem definition, the use of computers - including modelling, database and decision support systems - and implementation. A major feature of the book is the emphasis on case studies, illustrating the value of the "decision tools" approach for practical pest management. Consequently it is aimed at research scientists, students, practitioners and all concerned with applying current knowledge to improving pest management.
