Abstract
The pharmacological and immunological properties of the venom of Megascolia flavifrons are compared with those of bradykinin and a number of bradykinin analogues. It is postulated that this venom contains a peptide, megascoliakinin, with a bradykinin-like sequence of amino acids, elongated at the C-terminal end with an unknown structure.
