We study the existence and propagation of approximate travelling waves of generalized KPP equations with seasonal multiplicative white noise perturbations of Ito type. Three regimes of perturbation are considered: weak, mild, and strong. We show that weak perturbations have little effect on the wave-like solutions of the unperturbed equations, while strong perturbations essentially destroy the wave and force the solutions to die down. For mild perturbations, we show that there is a residual wave form but propagating at a different speed to that of the unperturbed equation. In the Appendix, J. G. Gaines illustrates these different regimes by computer simulations.
