Data: Female-limited responses in remating rate and mating duration in the experimental evolution of a beetle Callosobruchus chinensis

Mating rate optima often differ between the sexes: males may increase their fitness by multiple mating, but for females, multiple mating confers little benefit and can often be costly (especially in taxa without nuptial gifts or mala parental care). Sexually antagonistic evolution is thus expected in traits related to mating rates under sexual selection. This prediction has been tested by multiple studies that applied the experimental evolution technique, which is a powerful tool to directly examine the evolutionary consequences of selection. Yet, the results so far only partly support the prediction. Here we provide another example of experimental evolution of sexual selection, by applying it for the first time to the mating behavior of a seed beetle Callsorobruchus chinensis. We found a lower remating rate in polygamy-line females than in monogamy-line (i.e. no sexual selection) females after 21 generations of selection. Polygamy-line females also showed a longer duration of first mat..., After the experimental evolution of sexual selection (forced monogamy vs. polygamy), remating rates are examined on a seed beetle, Callosobruchus chinensis. In addition, the mating duration of the first mating was observed for the evolutionary line beetles., , # The data underlying \"Female-limited responses in remating rate and mating duration in the experimental evolution of a beetle *Callosobruchus chinensis*\"

This dataset is of mating behaviours of a seed beetle, *Callosobruchus chinensis*. The experimental evolution of sexual selection (three lines of forced monogamy vs. three lines of polygamy) was performed for 21 generations (with some intervening generations with the middle-class-neighbourhood design; see Kyogoku & Sota 2020 J Evol Biol 34, 501-511, DOI:10.1111/jeb.13753 for details). After common garden rearing, the beetles were subjected to mating trials. There are four CSV files.

两性的交尾率最适值往往存在差异：雄性可通过多次交尾提升自身适合度（fitness），但对雌性而言，多次交尾几乎无益处，且通常会带来代价（尤其是在缺乏求偶馈赠（nuptial gifts）或亲代抚育（parental care）的类群中）。因此，在性选择（sexual selection）作用下，与交尾率相关的性状预期会发生性拮抗进化（sexually antagonistic evolution）。已有多项研究借助实验进化（experimental evolution）这一可直接检验选择的进化后果的有力工具，对该预测进行了验证，但截至目前的研究结果仅部分支持该假说。本研究提供了又一个性选择实验进化的案例——首次将该方法应用于种子甲虫Callsorobruchus chinensis的交尾行为。经过21代选择后，我们发现多配制系雌性的再交尾率低于单配制系（即无性别选择）的雌性。多配制系雌性的首次交尾时长也更长……
在对种子甲虫Callosobruchus chinensis开展性选择实验进化（强制单配制vs多配制）后，研究人员对其再交尾率进行了检测。此外，还观察了进化系甲虫的首次交尾时长。

本数据集包含种子甲虫Callsorobruchus chinensis的交尾行为数据。研究开展了21代的性选择实验进化，设置3个强制单配制进化系与3个多配制进化系（部分中间代采用了中邻群体设计，详细方法参见Kyogoku & Sota 2020, Journal of Evolutionary Biology, 34: 501-511, DOI:10.1111/jeb.13753）。经过同质园饲养后，对甲虫开展交尾试验。本数据集包含4个CSV格式文件。
