To assess how a grate covering a catch basin impacts oviposition by mosquitoes, a field study was conducted in south Florida using containers with two types of covers, with openings of equal area, but different configurations. One opening mimicked a catch basin grate with 16 small openings, while the other cover had just one large opening. The number and presence of egg rafts in six of each container and cover combination was recorded over 18 nights at two field sites, consisting of a wastewater management facility area and residential subdivision. Three mosquito species, all belonging to the subgenus accounted for more than 99% of total egg rafts collected: ( = 1766), ( = 754) and ( = 526). Approximately 90% of and Cx. egg rafts were deposited in the containers with the large opening cover; whereas more egg rafts were laid in the containers with small opening covers than those of and combined. Similar patterns of egg laying activity were noted at each sampling stations. These results suggest that for locating oviposition sites may rely more on olfactory clues, while other species depend more on visual clues.
为评估覆盖集水池的篦子对蚊子产卵的影响，在佛罗里达州南部进行了一项实地研究，使用带有两种类型盖子的容器，两种盖子开口面积相等，但形状不同。一种开口模仿有16个小开口的集水池篦子，而另一种盖子只有一个大开口。在两个实地地点，包括一个废水管理设施区域和一个住宅小区，在18个晚上记录了每种容器和盖子组合的六个容器中卵块的数量和存在情况。三种蚊子，均属于该亚属，占收集到的总卵块的99%以上：（ = 1766），（ = 754）和（ = 526）。大约90%的和库蚊属卵块产在有大开口盖子的容器中；而在有小开口盖子的容器中产卵的埃及伊蚊卵块比和库蚊属的总和还多。在每个采样站都注意到了类似的产卵活动模式。这些结果表明，对于寻找产卵地点，埃及伊蚊可能更多地依赖嗅觉线索，而其他种类则更多地依赖视觉线索。
