Abstract Evolution of increased immune defence is often limited by costs: correlated changes in other traits (viz. life‐history traits) that otherwise reduce the fitness host organisms. Experimental evolution studies are useful for understanding function and traits. We experimentally evolved replicate Drosophila melanogaster populations to better survive infection challenges with an entomopathogenic bacteria, Enterococcus faecalis . Within 35 generations directional selection, selected showed a marked increase post‐infection survival than ancestrally paired controls. next measured various these populations. Our results show do not differ from control larval development time body weight at eclosion. No difference also observed case fecundity longevity (following acute phase infection), either when flies were subjected or uninfected, although infected all die much earlier uninfected flies. Selected equally good occasionally as surviving abiotic stressors (starvation desiccation), more susceptible stress Therefore, we conclude (a) D. can rapidly evolve be E. , (b) against entails no cost hosts (c) evolving biotic threat (pathogen) does make stressors.
