ABSTRACT Satyrization, a form of asymmetric reproductive interference, has recently been shown to play a role in competitive displacements of Aedes aegypti (L.) by Aedes albopictus (Skuse). Furthermore, female Ae. aegypti from populations in sympatry with Ae. albopictus have evolved reproductive character displacement and changes in mating behavior to reduce interspecific mating. In this article, we examine evolutionary responses of males to interspecific mating and show that satyrization has also evoked reproductive character displacement in males. We demonstrate that the presence of heterospecific females negatively influences conspecific mating success in male Ae. aegypti, most likely due to misdirected courting or mating efforts, and that males of this species from populations in sympatry with Ae. albopictus have evolved to be less influenced by the presence of heterospecific females than their allopatric counterparts. Conversely, we suggest that the presence of conspecifics may, in some circumstances, increase interspecific mating. This study demonstrates that co-occurrences of these two invasive species may lead to evolution and adaptation of reproductive behaviors to changing circumstances. Understanding the processes driving development of mate choice preferences or avoidance mechanisms may help predict future changes in the distribution and abundance of insect vectors or pests.

种间求偶对埃及伊蚊和白纹伊蚊（双翅目：蚊科）雄性交配成功的影响


摘要 饱和化是一种不对称生殖干扰形式，最近已被证明在白纹伊蚊 (Skuse) 竞争性取代埃及伊蚊 (L.) 中发挥作用。此外，女性Ae。埃及伊蚊来自与伊蚊同源的种群。白纹伊蚊进化出了生殖特征的位移和交配行为的变化，以减少种间交配。在本文中，我们研究了雄性对种间交配的进化反应，并表明萨蒂化也引起了雄性生殖特征的位移。我们证明，异种雌性的存在会对雄性伊蚊的同种交配成功产生负面影响。埃及伊蚊，很可能是由于错误的求爱或交配努力，并且该物种的雄性来自与伊蚊同族的种群。与异域同类相比，白纹伊蚊已经进化到较少受异种雌性存在的影响。相反，我们认为，在某些情况下，同种动物的存在可能会增加种间交配。这项研究表明，这两种入侵物种的共存可能会导致生殖行为的进化和适应不断变化的环境。了解驱动配偶选择偏好或回避机制发展的过程可能有助于预测昆虫媒介或害虫的分布和丰度的未来变化。
