攻击性特征的偏侧化（即大脑左右侧的功能和/或结构专门化）已经在许多脊椎动物中进行了研究，而无脊椎动物的证据很少。苔藓虫雌性对不受欢迎的雄性表现出攻击性反应，用后腿进行排斥踢。在这项研究中，我们研究了亚洲虎蚊，白纹伊蚊的女性踢行为的偏侧化。我们发现了一个右偏的人口水平侧踢行为。对雌性蚊子的四个重复测试阶段证实了优先使用右腿。然而，当使用左腿时，每次排斥事件的平均踢腿次数与使用右腿时没有差异。左踢和右踢行为都能成功地取代不受欢迎的伴侣。这是关于蚊子行为偏侧化的第一份报告。
Lateralisation (i.e. functional and/or structural specialisations of left and right sides of the brain) of aggressive traits has been studied in a number of vertebrates, while evidence for invertebrates is scarce. Mosquito females display aggressive responses against undesired males, performing rejection kicks with the hind legs. In this research, we examined lateralisation of kicking behaviour in females of the Asian tiger mosquito, Aedes albopictus. We found a right-biased population-level lateralisation of kicking behaviour. Four repeated testing phases on mosquito females confirmed the preferential use of right legs. However, when left legs were used, the mean number of kicks per rejection event was not different to that performed with right legs. Both left and right kicking behaviour lead to successful displacement of undesired partners. This is the first report about behavioural lateralisation in mosquitoes.
