Neuromuscular Mechanisms of Insect Flight

  • Ann E. Kammer
  • Mary B. Rheuben


The stringent requirements for successful flapping flight have resulted in remarkable adaptions of the skeleton, muscles and nervous system of animals capable of this means of locomotion. The wings have a large surface area but are lightweight to reduce the inertial costs of flapping. The flight muscles can contract and relax repeatedly and rapidly. Their high metabolic rate is adequately supported by sufficient fuel and oxygen that in many species flights lasting for hours are possible. The central nervous system produces the motor output that coordinates the contractions of the flight muscles and integrates information from a variety of receptors to adjust the motor pattern as required by environmental stimuli and the behavior of the insect. Some of these aspects of insect flight are discussed in other chapters of this volume. In this chapter we consider three topics: (1) flight muscles and their innervation, (2) motor patterns and their possible usefulness as an indicator of metabolic costs, and (3) putative roles of octopamine in flight.
