埃及伊蚊Aedes aegypti和Ae.白纹伊蚊是入侵性蚊子，能够传播虫媒病毒，如登革热、基孔肯雅热、黄热病和寨卡病毒。最近的空间分布变化表明，有一个复苏的Ae。佛罗里达某些地区的埃及人。在缺席26年后，Ae。2019年11月，在佛罗里达盖恩斯维尔市中心的一个街区收集了埃及伊蚊幼虫。随后的调查证实，Ae。白纹伊蚊完全被Ae.埃及在这个社区，而Ae。albopictus和Ae.埃及共存围绕这个社区的重点，和Ae。自20世纪90年代以来，仅在该市和该县的其他地方发现了白纹伊蚊。调查显示，Ae。埃及人在盖恩斯维尔市中心地区死灰复燃，并积极向邻近地区扩散。因此，Ae。Aegypti可能会取代Ae。正如最近在佛罗里达东北部沿海城市报道的那样，在佛罗里达中北部的盖恩斯维尔市，白纹伊蚊在更多的地区出现。
Aedes aegypti and Ae. albopictus are invasive mosquitoes, capable of vectoring arboviruses such as dengue, chikungunya, yellow fever, and Zika. Recent shifts in spatial distribution indicate there is a resurgence of Ae. aegypti in certain regions of Florida. After a 26-year absence, Ae. aegypti larvae were collected in a downtown neighborhood in Gainesville, Florida, in November 2019. Subsequent surveys confirmed that Ae. albopictus was completely displaced by Ae. aegypti in this neighborhood, whereas Ae. albopictus and Ae. aegypti coexisted around this community focus, and Ae. albopictus alone has been found elsewhere in the city and county since the 1990s. Field surveys revealed that Ae. aegypti is resurging in the downtown area of Gainesville and is actively dispersing to adjacent neighborhoods. Thus, Ae. aegypti could potentially replace Ae. albopictus across more of urban Gainesville in north-central Florida, as reported recently in coastal cities of northeastern Florida.
