A Langevin equation for charged particles in a plasma with electrostatic turbulence is developed from first principles and in consistency with the kinetic theory in polarization approximation. For the case of ion‐acoustic and electrostatic lower‐hybrid‐drift turbulence approximate expressions for the space‐time spectral density of the wave energy are given and estimates of the intensities of the stochastic wave forces are made. The application is done for the plasmas of the earth's magnetosphere, the solar wind and solar flares. It seems, that ion‐acoustic and electrostatic lower‐hybrid‐drift waves can contribute to electron chaotization in different regions of the space plasma.
