The vector mosquitoes Aedes aegypti (L.), native to Africa, and Aedes albopictus (Skuse), native to Asia, are widespread invasives whose spatial distributions frequently overlap. Predictive models of their distributions are typically correlative rather than mechanistic, and based on only abiotic variables describing putative environmental requirements despite extensive evidence of competitive interactions leading to displacements. Here we review putative roles of competition contributing to distribution changes where the two species meet. The strongest evidence for competitive displacements comes from multiple examples of habitat segregation where the two species co-occur and massive reductions in the range and abundance of A. aegypti attributable to A. albopictus invasions in the southeastern U.S.A. and Bermuda (U.K). We summarize evidence to support the primacy of asymmetric reproductive interference, or satyrization, and larval resource competition, both favoring A. albopictus, as displacement mechanisms. Where evidence of satyrization or interspecific resource competition is weak, differences in local environments or alternative ecologies or behaviors of these Aedes spp. may explain local variation in the outcomes of invasions. Predictive distribution modeling for both these major disease vectors needs to incorporate species interactions between them as an important process that is likely to limit their realized niches and future distributions. Experimental tests of satyrization and resource competition are needed across the broad ranges of these species, as are models that incorporate both reproductive interference and resource competition to evaluate interaction strengths and mechanisms. These vectors exemplify how fundamental principles of community ecology may influence distributions of invasive species.

传染媒介在哪里碰撞：塑造已实现的生态位的机制对入侵伊蚊的范围建模的重要性。

非洲原产的媒介蚊埃及伊蚊（L.）和亚洲原产的媒介白纹伊蚊（Skuse）是广泛的入侵者，其空间分布经常重叠。它们分布的预测模型通常是相关的而不是机制的，并且尽管描述了竞争相互作用导致位移的大量证据，但仅基于描述假定的环境要求的非生物变量。在这里，我们回顾了竞争在两个物种相遇时对分布变化做出贡献的假定角色。竞争性流离失所的最有力证据来自多个生境隔离的例子，其中两种物种同时发生，而埃及白纹伊蚊的分布范围和数量则大量减少，归因于美国东南部和百慕大（英国）的白纹伊蚊的入侵。我们总结了证据，以支持不对称生殖干扰或讽刺化和幼虫资源竞争的优势，两者均偏爱白纹曲霉作为置换机制。在讽刺或种间资源竞争的证据薄弱的地方，这些伊蚊属物种在当地环境或替代生态或行为上的差异。可以解释入侵结果的局部差异。这两种主要疾病媒介的预测分布模型都需要将它们之间的物种相互作用纳入其中，这是一个重要的过程，很可能会限制其已实现的生态位和未来的分布。需要对这些物种的广泛范围进行讽刺和资源竞争的实验测试，结合生殖干扰和资源竞争以评估相互作用强度和机制的模型。这些媒介例证了社区生态学的基本原理如何影响入侵物种的分布。
