    Recent theory predicts that personality traits
    contributing to resource intake rates could reflect the
    individual’s condition-dependent capacity to resist parasites
    and pathogens. Since females often prefer mates with strong
    immune defence, females could potentially gain fitness
    benefits by using male’s behavioral type (BT) as one mate
    choice criteria. We studied if female field crickets base their
    mate choice on male boldness and if the boldness would
    predict survival under challenge to opportunist pathogen
    Serratia marcescens. In addition, we tested if three different
    females would prefer the same males. Boldness did not
    explain individual’s lifespan in experimental infection.
    All the three females preferred one male within pair over
    the other male in 26.9% of the mate choice tests, but the
    preferred male varied between the females. Our results
    suggest that females show preferences for bold BTs, but
    that male boldness may not reflect his capacity to resist
    bacterial pathogens
