This introductory paper to the Rutgers Symposium outlines the background of the development of resistance to insecticides and discusses various aspects of the problem in the context of modern agrochemical practice. Resistance can only be countered by properly mounted management programmes, but the successful design and implementation of these requires a thorough understanding of the fundamental processes involved, and the importance of continuing research into these is stressed.
