It has been shown that sheared pair-ion flows can generate low frequency electrostatic waves in a nonuniform dust pair-ion magnetoplasma. Linear analysis shows that the electrostatic driftlike waves can become unstable due to shear flow. The conditions of modes instability are given. These excited modes gain large amplitudes and start interacting among themselves. The interaction is governed by the nonlinear equations containing the vector nonlinearities. Stationary solutions of the nonlinear mode coupling equations can be represented in the form of a vortex chain and a dipolar vortex. The relevance of the work to laboratory plasmas are pointed out.
