2006年，在佐治亚州亚特兰大市的一条城市河流Tanyard Creek中进行了一项蚊子生态学的纵向研究，该河流接收来自亚特兰大联合污水溢流系统的雨水和废水。致倦库蚊是优势种，但在春季也有大量的休养生息库蚊，也收集到数量有限的黑须库蚊和点翅按蚊。蚊子密度的显着差异与较大的密度与侧池的水和死水。蚊子的数量主要是由超过15公斤/分钟的污水排放的流洪水调节。这些洪水与显着的立即减少，但不完全消除，蚊子从坦亚德溪。洪水过后5-10天内，苔藓数量会反弹，并迅速达到高密度。
A longitudinal study of mosquito ecology in Tanyard Creek, an urban stream in Atlanta, GA, that receives combined storm and waste water effluent from the Atlanta combined sewage overflow system, was undertaken in 2006. Culex quinquefasciatus was the dominant species found, but Culex restuans was also abundant during the spring with limited numbers of Culex nigripalpis and Anopheles punctipennis also collected. Significant differences in mosquito densities were found with Greater densities associated with side pools of water and stagnant water. Mosquito numbers are regulated largely by flooding of the stream by effluent discharges exceeding 15 kgal/min. These floods are associated with significant immediate reductions, but not complete elimination, of mosquitoes from Tanyard Creek. Mosquito numbers rebound within 5-10 days after such floods and rapidly reach high densities.
