The alpha -glucosidase activity of whole haemolymph was investigated in adult males of Periplaneta americana (L.). Two electrophoretically distinguishable enzymes capable of hydrolysing alpha -glucosidic linkages were present in the serum component of the haemolymph, and one of these hydrolysed trehalose. Trehalase activity was also present in haemocytes, and the haemocyte enzyme shared an identical electrophoretic mobility and similar pH sensitivity with the serum trehalase.
