Adult males of Periplaneta americana (L.) that had been starved for 24 h were allowed to feed for 20 min on banana paste to which 1% by weight of sodium arsenate or sodium arsenite had been added. In tests 20 h later, more alkaline phosphatase was detected in the mid-gut epithelial cells of these cockroaches than in those of others that had been fed on banana paste alone.
