New theoretical instability strips for δ Sct and γ Dor stars are presented. These results have been obtained taking into account the perturbation of the convective flux following the treatment of Gabriel (1996BASI...24..233G). For the first time, the red edge of the δ Sct instability strip for non-radial modes is obtained. The influence of this time-dependent convection (TDC) on the driving of the γ Dor gravity modes is investigated. The results obtained for different values of the mixing-length parameter α are compared for the γ Dor models. A good agreement with observations is found for models with α between 1.8 and 2.0.
