The paper studies the exponential and non--exponential convergence rate to zero of solutions of scalar linear convolution Ito-Volterra equations in which the noise intensity depends linearly on the current state. By exploiting the positivity of the solution, various upper and lower bounds in first mean and almost sure sense are obtained, including Liapunov exponents.
