Virasoro constraints for orbifold Gromov-Witten theory are described. These constraints are applied to the degree zero, genus zero orbifold Gromov-Witten potentials of the weighted projective stacks P(1, N), P(1, 1, N), and P(1, 1, 1, N) to obtain formulas of descendant cyclic Hurwitz-Hodge integrals.
