The temporal abundance and percent insemination of newly-emerged adult female Psorophora columbiae were investigated in riceland sites near Anahuac, TX. Pre- and postmating nights were characterized by low numbers of females and little mating activity (no significant increase in percent insemination) occurring in the study site. Mating nights were characterized by high female abundance in the study site before sunset then steadily decreased until a stable, low level of abundance was reached approximately 2 to 2.5 hr after sunset. On mating nights, percent insemination of female mosquitoes in the study site remained low until sunset, after which it steadily increased until a maximum was reached about 2 hr after sunset. On each mating night, approximately 2 to 2.5 hr after sunset, a mass exodus from the site by primarily mated females with some males was observed.
在得克萨斯州阿纳胡阿克附近的稻田地点，对新羽化的成年雌性哥伦比亚骚蚊的时间丰度和受精百分比进行了调查。交配前和交配后的夜晚，研究地点的雌性数量较少，交配活动也很少（受精百分比没有显著增加）。交配的夜晚，日落前研究地点的雌性数量很多，然后稳步下降，直到日落后约2至2.5小时达到稳定的低丰度水平。在交配的夜晚，研究地点雌性蚊子的受精百分比在日落前一直很低，之后稳步上升，直到日落后约2小时达到最大值。在每个交配的夜晚，日落后约2至2.5小时，观察到主要是已交配的雌性蚊子和一些雄性蚊子大量离开该地点。
