A new kinetic integral equation for the study of the ion temperature gradient driven mode in toroidal geometry is developed that includes the ion toroidal (curvature and magnetic gradient) drift motion {omega}{sub D}, the mode coupling from finite {kappa}{sub {parallel}} due to the toroidal feature of the sheared magnetic configuration. The integral equation allows the stability study for arbitrary {kappa}{sub {parallel}} {upsilon}{sub i}/({omega} {minus} {omega}{sub D}) and {kappa}{perpendicular}{rho}{sub i}. A systematic parameter study is carried out for the low {beta} circular flux surface equilibrium. Possible correlations between the unstable mode characteristics and some experimental results such as fluctuation spectrum and anomalous ion transport measurements are discussed.
