Satyrization, a form of asymmetric reproductive interference, has recently been shown to play a role in competitive displacements of (L.) by (Skuse). Furthermore, female from populations in sympatry with 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 , most likely due to misdirected courting or mating efforts, and that males of this species from populations in sympatry with 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.
“拟态化”是一种不对称生殖干扰形式，最近研究表明它在（L.）被（Skuse）竞争性取代的过程中发挥了作用。此外，与（Skuse）同域分布种群中的雌性（L.）已经进化出繁殖特征替代以及交配行为的变化，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“拟态化”也在雄性中引发了繁殖特征替代。我们证明，异种雌性的存在对雄性（L.）的同种交配成功率有负面影响，这很可能是由于求偶或交配努力的方向错误，并且与（Skuse）同域分布种群中的该物种雄性相比，其异地种群的雄性受异种雌性存在的影响较小。相反，我们认为在某些情况下，同种个体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导致繁殖行为随着环境变化而进化和适应。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未来分布和数量的变化。
