Structure and ultrastructure of the insect midgutthe subject is neither appropriate nor necessary here. Rather, we aim to describe the structural components of the midgut, introduce some terminology, and provide a framework for the subsequent chapters. Studies on midgut structure are probably the least topical of all those covered in this text and

The peritrophic matrix health. The insect midgut has pivotal roles in both of these aspects of the relationship between humans and insects (see also Chapters 6–8 and 16). In particular, the functions of the peritrophic matrix (PM) which lines the gut of most insects, is intimately associated with the digestive process in

Digestive enzymesve attracted the attention of researchers for centuries (Wigglesworth, 1972). Perhaps one significant factor for their success is the ability of insects to exploit a wide range of organic material in their nutrition. These materials extend from refractory wood, humus, wool and wax to the more digest

Compartmentalization of digestion This spatial and temporal separation is a result of morphological features of the gut tract combined with fluid fluxes that occur within the midgut. These features effectively compartmentalize buffering mechanisms responsible for pH and redox potential, enzymatic activity, absorption of nutrients,
