Abstract- In this paper, the instability of Dust-Ion-Acoustic waves in the presence of the dust charge fluctuations in a collisionless unmagnetized dusty plasmas is investigated by kinetic theory. We consider Maxwellian distribution for plasma particles in the equilibrium and negatively charged dust grains. It is shown that dust-ion-acoustic wave instability can exist even if the drift speeds of the plasma particles are equal to zero. The results of kinetic theory are compared with those of fluid theory.
