We find that the indirect effect of sterilizing pathogens on mortality of the infected hosts, mediated by a fecundity-longevity trade-off, may cause hosts to attain densities higher than when there is no effect of pathogens on host mortality. As a consequence, using sterilizing pathogens as agents of pest control may actually be less effective than previously thought. We even suggest that if sexual selection acts on the host species then the presence of sterilizing pathogens may even enhance host densities above the levels achieved without infection.
