Insect physiology is currently undergoing a revolution with the increased application of molecular biological techniques to investigate the molecular mechanisms underlying the physiological responses to insect cells. Advances in Insect Physiology is commited to publishing high quality reviews on molecular biology and molecular genetics in areas where they provide an increased understanding of physiological processes in insects. Volume 26 of this classic seriescontinues to provide up-to-date reviews on topical subjects of importance to all invertebrate physiologists and neurobiologists and contains increased coverage on the molecular biology of insect physiology.
