Physiological Entomology is designed primarily to serve the interests of experimentalists who work on insects and other arthropods. It thus has a bias towards physiological and experimental approaches to understanding behaviour, but it also retains the Royal Entomological Society's interest in the general physiology of arthropods. The broad subject coverage of the Journal includes:

• experimental analysis of behaviour;
• behavioural physiology and biochemistry;
• neurobiology and sensory physiology;
• general physiology;
• circadian rhythms and photoperiodism.
• chemical ecology
