Two invasive mosquitoes, Aedes aegypti and Aedes albopictus, have been interacting during the course of a rapid range expansion by A. albopictus. We investigated the potential for interspecific feeding interference by male mosquitoes interacting with females within and between these species. A. aegypti feeding on both sugar and blood was suppressed when females of this species were exposed to A. albopictus males, but no change was observed when exposed to conspecifics. A. albopictus feeding was not affected by males of either species. The potential consequences of these behaviors are discussed within the context of other known interspecific effects, all of which appear to favor the displacement of A. aegypti by A. albopictus.
两种入侵性蚊子，埃及伊蚊和白纹伊蚊，在白纹伊蚊快速扩张分布范围的过程中相互作用。我们研究了在这些物种内部以及不同物种之间，雄性蚊子与雌性交配时种间取食干扰的可能性。当埃及伊蚊的雌性个体接触到白纹伊蚊的雄性个体时，以糖和血液为食的埃及伊蚊的取食行为受到抑制，但当接触到同种雄性时未观察到变化。白纹伊蚊的取食行为不受这两个物种中任何一个物种雄性个体的影响。我们在其他已知种间效应的背景下讨论了这些行为的潜在后果，所有这些效应似乎都有利于白纹伊蚊取代埃及伊蚊。
