Summary
In preparations of crushed whole spider mites (Tetranychus urticae Koch), the enzymes capable of hydrolyzing carbohydrates were identified. The products of the enzymic hydrolysis were detected by paper chromatography. The following substrates were hydrolyzed: Starch, maltose, sucrose, trehalose, melibiose, lactose, melezitose and raffinose. Not attacked were: Cellobiose, cellulose, pectin and pectic acid. In the homogenates there must be present an amylase, an α-glucosidase, a β-h-fructosidase, an α- and β-galactosidase. There is no indication for the presence of a β-glucosidase, a cellulase, a pectinase and polygalacturonase.
