Effects of β (plasma pressure/magnetic pressure) and Te/Ti (ratio of electron temperature to ion temperature) on the slab ion temperature gradient modes are studied locally for any β value in anisothermal hydrogenic plasmas with no impurities or fast ions. The stabilizing mechanism of finite β on the modes is investigated in detail. It is shown that increasing Te/Ti destabilizes the modes and that βi stabilizes the modes mainly by decreasing Te/Ti, while βe does so directly. βe is the dominant stabilizing factor for a fixed Te/Ti. The numerical results also indicate that the critical β(βc) for mode stabilization decreases as Te/Ti decreases. Ion heating favors the suppression of the ion temperature gradient modes in anisothermal plasmas for any β value.
