摘要：

The midgut of the blood-feeding fly Stomoxys calcitrans contains a specialized enzyme-producing region, the opaque zone, in which digestive enzymes are produced and stored prior to secretion. Evidence is presented which suggests that trypsin-like enzymes are produced as zymogens and stored within the cell in zymogen granules. Activation of trypsin-like enzyme precursor appears to be autocatalytic.
