We present a fitting formula for the non-linear evolution of the bispectrum
in CDM models, obtained from measurements in high resolution numerical
simulations. The formula interpolates between the perturbative and highly
non-linear regimes, and generalizes previous results obtained for scale-free
initial conditions.
