With new data on stellar opacity and equation of state, we computed the theoretical blue edges of the classical instability strip in the vicinity of the main sequence. The results were compared with observational data on δ Scuti variables using various diagrams (HR, log g – log Teff, Mv – (b – y)0 and so on). An example of these diagrams is shown in Fig. 1. Detailed results can be found in Pamyatnykh (2000).
