# Insect Hormones: The Control of Moulting

Produced by the BBC for the British Open University

Observes the moulting of the tobacco hornworm, a complex process controlled by hormone systems, endocrine glands, and the central nervous system of the insect. Uses animation and close-up photography to document the timing and nature of events that trigger the signal to moult from larva to pupa. Proposes methods and a rationale for regulating hormonal levels in order to control the organism's physiological development. From the Biology: Form and Function series
