Abstract. We investigate the link of cyclic behavior between a bounded operator and its Generalized Aluthge transforms. As an application, we characterize $\omega $-hyponormal operators for which the adjoint is hypercyclic or supercylic in terms of analytic spectral spaces. This extends a recent result of N. Feldman, V. G. Miller and T. L. Miller given for hyponormal operators.
