The influence of female age on male mating preference and reproductive success has been studied using a promiscuous cabbage beetle, Colaphellus bowringi Baly (Coleoptera: Chrysomelidae). In a simultaneous choice test, middle-aged females had significantly greater mating success than young and old females. In single pair trials, when paired with middle-aged virgin males, middle-aged females mated faster, copulated longer, and had greater fecundity and fertility than young or old females, while the longevity of males was not significantly affected by female age. This study on C. bowringi suggests that middle-aged females are more receptive to mating, which can result in the highest male reproductive success.
本研究以拟态盘腹蝇科（Coleoptera：Chrysomelidae）的一种杂食性芫菁（Colaphellus bowringi Baly）为研究对象，探讨了雌性年龄对雄性交配偏好和繁殖成功的影响。在同时选择测试中，中年雌性的交配成功率显著高于年轻和年老的雌性。在单对试验中，与中年处女雄虫配对时，中年雌性交配更快，交配时间更长，产卵数和繁殖力均显著高于年轻或年老的雌性，而雄虫的寿命不受雌性年龄的显著影响。本研究表明，中年雌性对交配的接受度更高，这可能导致雄性获得最高的繁殖成功。
