尽管已经在昆虫中研究了雄性交配史对雌性生殖产量和寿命的影响，但在蜘蛛中进行的此类研究很少。在雌性一夫多妻而雄性一夫多妻的交配系统中，雌性可能会因与经历过连续交配的成功雄性交配而遭受精子和/或相关射精可能耗尽的风险。在这里，我们研究了雄性狼蛛的交配历史对雄性求偶和交配持续时间、雌性生殖适应性和雌性成年狼蛛寿命的影响。结果表明，雄性交配频率对其随后的交配成功率影响不大，在接受测试的 35 只雄性中，大约一半的雄性能够以 24 小时的间隔连续与 5 只处女雌性交配。雄性的交配史对其求爱持续时间影响不大。然而，雄性交配史显着影响雄性交配持续时间、雌性成年寿命和繁殖产量。交配更频繁的雄性交配时间更长，更有可能无法让其配偶产下一窝，尽管无论是第一窝还是第二窝，产卵数量和孵化数量没有显着差异。雄性黄芪的多次交配导致雌性成虫寿命显着缩短。我们的结果表明，单性雌性与多次交配的雄性交配可能会产生巨大的健康成本。
Although the effects of male mating history on female reproductive output and longevity have been studied in insects, few such studies have been carried out in spiders. In a mating system in which females are monandrous while males are polygynous, females may incur the risk by mating with successful males that have experienced consecutive matings and suffer from the possible depletion of sperm and/or associated ejaculates. Here, we examine the effects of male mating history on male courtship and copulation duration, female reproductive fitness, and female adult longevity of the wolf spider, Pardosa astrigera. Results indicated that male mating frequency had little effect on their subsequent copulation success, and of 35 males tested, about half of the males were able to copulate with five virgin females successively at an interval of 24 h. Male mating history had little effect on their courtship duration. However, male mating history significantly affected male copulation duration, female adult longevity, and reproductive output. Males that mated more frequently copulated longer and more likely failed to cause their mates to produce a clutch, although there was no significant difference in the number of eggs laid and the number of eggs hatched regardless of the first clutch or the second one. Multiple mating of male P. astrigera resulted in significant reduction in female adult longevity. Our results indicate that monandrous females mating with multiple-mated males may incur substantial fitness costs.
