Soil samples were collected over a 21/2-year period from microhabitats in fields planted to soybeans in Chambers County, TX, to study the oviposition behavior of Psorophora columbiae. An analysis of egg collection data gathered from the processing of 1,098 soil samples suggested that, during wet years, Ps. columbiae eggs tend to be scattered throughout soybean fields. During dry years, a greater abundance of eggs occur in the low areas of these types of fields. The data also suggested that oviposition by Ps. columbiae is concentrated in soil near the base of soybean plants rather than in open furrows between the rows of plants.
在得克萨斯州钱伯斯县种植大豆的田地微生境中，历时两年半采集土壤样本，以研究哥伦比亚库蚊的产卵行为。对从1098份土壤样本处理中收集到的虫卵数据进行分析表明，在湿润年份，哥伦比亚库蚊的卵往往散布在大豆田各处。在干旱年份，这类田地的低洼区域会出现更多虫卵。数据还表明，哥伦比亚库蚊的产卵集中在大豆植株基部附近的土壤中，而非植株行之间的开阔沟中。
