The course is designed to present the organisation of insect systems and metabolic processes. Topics include biochemical molecules and processes specific to insects, such as nature of insect fuel: metabolism; synthesis, storage, mobilisation, transport and utilisation in flight. There will also be discussion on the biochemistry of exoskeleton and regulation of metamorphosis; insect hormones affecting growth and development; insecticides and their modes of action; insecticidal proteins, biopesticide and mechanisms of insecticide resistance. Current trends in the application of molecular tools for the detection of resistance development in insects and approaches to insect control will be examined.
