Receptive females mitigate costs of sexual conflict.

摘要: Males typically gain fitness from multiple mating, whereas females often lose numerous potentially leading to sexual conflict over mating. This is expected favour the evolution of female resistance However, may incur male harassment if they refuse copulate; thus, greater increase costs imposed by males. Here, I show that mating raises disadvantages interacting with males when harmful in adzuki bean beetles, Callosobruchus chinensis. Females were artificially selected for higher and lower remating propensity evolved accept resist remating, respectively. Compared it suffered continuous exposure The a single measured effect on longevity did not differ among selection line females. study indicates receptive rather than resistant mitigate loss resulting conflict, suggesting even though harmful, can evolve additional
