Abstract
Necessary and sufficient conditions are obtained for all solutions of a class of linear scalar neutral-integrodifferential equations to have at least one zero. An application to an "equilibrium level-crossing" of a logistic integrodifferential equation with infinite continuously distributed delay is briefly discussed.
