Resumen:
Postcopulatory sexual selection has shaped the ornaments used during copulatorycourtship. However, we know relatively little about whether these courtship ornamentsare costly to produce or whether they provide indirect benefits to females.We used the mealworm beetle, Tenebrio molitor, to explore this. We challenged malesusing an entomopathogenic fungus and compared their courtship (frequency of legand antennal contacts to the female), copulation duration, number of eggs laid, andhatching rate against control males. Infected males copulated for longer yet they reducedtheir leg and antennal contacts compared to control males. However, therewas no obvious relation between infection, copulation duration, and courtship withegg production and hatching success. In general, our results indicate that the ornamentsused during postcopulatory courtship are condition-dependent.Moreover,such condition dependence cannot be linked to male fitness.
