Physiological Entomology broadly considers “how insects work” and how they are adapted to their environments at all levels from genes and molecules, anatomy and structure, to behaviour and interactions of whole organisms. We publish high quality experiment based papers reporting research on insects and other arthropods as well as occasional reviews. The journal thus has a focus on physiological and experimental approaches to understanding how insects function. The broad subject coverage of the Journal includes, but is not limited to: -experimental analysis of behaviour-behavioural physiology and biochemistry-neurobiology and sensory physiology-general physiology-circadian rhythms and photoperiodism-chemical ecology
