The importance of the search for pulsating stars of the δ Scuti type in multiple stellar systems is emphasized, in particular for the following objects: the evolutionary status of these systems, the interconnection between multiplicity and pulsation (Frolov et al., 1980), a verification of the theory of the turbulent mixing (Vauclair, 1976). A list of possible pulsating companions in visual and spectroscopic systems with foreseeable period and amplitude is given. Some preliminary results of a spectrophotometric survey begun at the Observatories of Milano - Merate and Bologna - Loiano are also given.
