We consider the Al-Omari and Gourley non-local reaction–diffusion population model with distributed maturity. Existence of monotone wavefronts for some particular probability distribution of maturity that permits the linear chain trick was previously obtained; here, we consider the most general form of such a distribution using some comparison arguments for abstract functional differential equations with infinite delay and a fixed point approach combined with the upper and lower solutions technique.

Keywords: non-local distribution; reaction–diffusion equation; infinite distributed maturity; monotone travelling front.
