  CCD observations of 68 eclipsing binary systems, candidates for containing
{\delta} Scuti components, were obtained. Their light curves are analysed using
the PERIOD04 software for possible pulsational behaviour. For the systems QY
Aql, CZ Aqr, TY Cap, WY Cet, UW Cyg, HL Dra, HZ Dra, AU Lac, CL Lyn and IO UMa,
complete light curves were observed due to the detection of a pulsating
component. All of them, except QY Aql and IO UMa, are analysed with modern
astronomical softwares in order to determine their geometrical and pulsational
characteristics. Spectroscopic observations of WY Cet and UW Cyg were used to
estimate the spectral class of their primary components, while for HZ Dra
radial velocities of its primary were measured. O - C diagram analysis was
performed for the cases showing peculiar orbital period variations, namely CZ
Aqr, TY Cap, WY Cet and UW Cyg, with the aim of obtaining a comprehensive
picture of these systems. An updated catalogue of 74 close binaries including a
{\delta} Scuti companion is presented. Moreover, a connection between orbital
and pulsation periods, as well as a correlation between evolutionary status and
dominant pulsation frequency for these systems, is discussed.
