We present an influence of mass loss, element diffusion and convective overshooting on instability areas of SPBsg stars with masses of 13 - 18 M⊙. Evolutionary phases before and after helium core ignition are considered. We discuss how these effects affect the structure of the blue loops and hence a coverage of instability areas.
