Entomology as a branch of biological science has undergone rapid expansion and development in recent decades. Greater emphasis is now placed on topics such as modelling and biochemical techniques, with new approaches to the study of insect behavior and insecticide efficacy making inroads into traditional approaches. Aimed at advanced undergraduate and postgraduate students in entomology and pest management, this book aims to integrate the new approaches and technologies with traditional and well-proven methods. It provides a critical analysis and evaluation of methods available, through reference to general principles, but emphasis is also placed on providing detailed descriptions of methods and their applications.
