Abstract
1. 1. A cathepsin D-like proteinase has been identified in the posterior midgut of species from 6 families of Hemiptera. 2. 2. Identification was based on maximal haemoglobin hydrolysis at either pH 2.5 or pH 3.0, pepstatin inhibition and decreased hydrolysis of albumin compared to haemoglobin. 3. 3. The occurrence of catheptic digestive proteinases in Hemipteran insects is discussed in relation to the evolution of this insect order.
