Aedes albopictus has been found in 53 of the 67 Florida counties. The initial discoveries in 11 of these counties were made in cemeteries. At several locations, Ae. albopictus became well-established in cemeteries before appearing in nearby accumulations of waste tires. The recycling of plastic floral baskets may be aiding the spread of Ae. albopictus. Mosquitoes were commonly found in all types of flower-holding containers in cemeteries, except bronze vases. In the laboratory, most Aedes aegypti eggs laid in bronze vases hatched, but larvae subsequently died. The spread of Ae. albopictus in cemeteries seems to occur at the expense of Ae. aegypti populations. At one cemetery immature Ae. albopictus and Ae. aegypti were found in about 70% of the Aedes-positive containers at the start of a monitoring program. In subsequent collections from this site, Ae. albopictus was found in nearly all Aedes-positive containers, whereas there was a progressive decrease in containers with Ae. aegypti. This trend did not appear to be the result of any seasonal pattern because in a nearby cemetery where Ae. albopictus was absent, Ae. aegypti did not show a similar decline. Limiting flower-holding containers to those with drain holes or to bronze vases would greatly limit mosquito production.
在佛罗里达州67个县中的53个县发现了白纹伊蚊。其中11个县最初是在墓地发现的。在几个地点，白纹伊蚊在墓地中大量繁殖后才出现在附近堆积的废旧轮胎中。塑料花篮的回收利用可能有助于白纹伊蚊的传播。在墓地中，除了青铜花瓶外，各类插花容器中都普遍发现有蚊子。在实验室中，大多数产在青铜花瓶里的埃及伊蚊卵孵化了，但幼虫随后死亡。白纹伊蚊在墓地中的传播似乎是以牺牲埃及伊蚊种群为代价的。在一个墓地，在监测项目开始时，约70%的伊蚊阳性容器中发现了未成熟的白纹伊蚊和埃及伊蚊。在该地点随后的采集过程中，几乎所有伊蚊阳性容器中都发现了白纹伊蚊，而含有埃及伊蚊的容器数量则逐渐减少。这种趋势似乎不是任何季节性模式导致的，因为在附近一个没有白纹伊蚊的墓地中，埃及伊蚊并没有出现类似的减少情况。将插花容器限制为有排水孔的容器或青铜花瓶，将极大地限制蚊子的繁殖。
