Resumen:

Females may choose their male mates. However, both sexes may engage in a kind of dispute not to be coerced into mating (for females) and to be chosen (for males). These two hypotheses (called female choice and sexual conflict, respectively) are currently in vogue in studies of sexual reproduction. This chapter highlights some instances where both can be tested in odonates. These instances are: during copula invitation by males, for the duration of copulation, and during the male post-copulatory displays preceding and during oviposition. There are four other aspects that may be investigated to see the prevalence of each hypothesis: the differences of genitalic diversity across populations, the genitalic complexity at the multiple species level, the female benefits when mating with 'attractive' males, and the costs to evade superfluous matings. © Oxford University Press 2008.
