1. 1. The properties of β-acetylglucosaminidase, acid phosphatase, aminopeptidase, cathepsin B-like proteinase, α-galactosidase, α-glucosidase, detergent-solubilized membrane-bound α-glucosidase, β-glucosidase, α-mannosidase and detergent-solubilized membrane-bound α-mannosidase from posterior midgut of Rhodnius prolixus adults were determined by density-gradient centrifugation and kinetic methods. 2. 2. The posterior midgut hydrolases from R. prolixus adults and nymphs were found to be very similar. 3. 3. The results lend support to the hypothesis that digestive enzymes are, in contrast to holometabolous insects, identical in young and adult forms of hemimetabolous insects.
