研究雄性和雌性交配行为的功能对于我们试图理解交配系统的进化是至关重要的。物种内不同种群之间交配行为的差异为探索行为可能如何共同变化提供了一个有用的机会，尽管比较研究的数量仍然相当少。种群交配行为的差异也可能对生殖隔离的演变、种群内和种群间遗传多样性的分布以及这些种群的相关适应能力产生重要影响。在这里，我们研究了来自英国和俄罗斯的两个种群的雄性和雌性瓢虫的交配行为。我们发现，在雌性拒绝行为的持续时间和交配持续时间方面，雄性和雌性交配行为在种群之间存在差异，并且这种差异与个体交配伴侣来自哪个种群无关。我们的数据证实，在两点瓢虫的不同种群中，性选择和生殖行为的模式可能会有所不同。这种变异在多大程度上是由于当前的生态因素或种群历史造成的，对于该物种和许多其他物种来说，仍有待验证。
Investigating the function of both male and female mating behaviours is essential in our attempts to understand the evolution of mating systems. Variation in mating behaviours among different populations within a species provides a useful opportunity to explore how behaviours may co-vary, although comparative studies are still rather few in number. Population variation in mating behaviour may also have important implications in terms of the evolution of reproductive isolation, the distribution of genetic diversity within and between populations, and the associated ability of those populations to adapt. Here we consider male and female mating behaviour in two populations of the two-spot ladybird, Adalia bipunctata, from the UK and Russia. We find that male and female mating behaviours differ between the populations in terms of the length of female rejection behaviour and the duration of mating, and that this variation is independent of which population an individual's mating partner is from. Our data confirm that patterns of sexual selection and reproductive behaviour are likely to vary across populations in the two-spot ladybird. The extent to which this variation is due to current ecological factors or population history remains to be verified for this species, as for many others.
