Inequalities of the form parallel to uK f parallel to(q) <= C(parallel to rho f parallel to(p) + parallel to vH f parallel to(p)), f >= 0, are considered, where K is an integral operator of Volterra type and H is the Hardy operator. Under some assumptions on the kernel K we give necessary and sufficient conditions for such an inequality to hold.
