The effect of organic enrichment of the larval habitat on mosquito oviposition was determined in 2 replicated field experiments. In the first study, Culex stigmatosoma and Culex quinque-fasciatus oviposition (as measured by the number of early instar larvae) reached a maximum peak soon after flooding and then declined to a substantially lower equilibrium level. A group of ponds that later received supplemental organic matter had a significant increase in oviposition soon after the additional organic matter was added. In the second experiment, a similar ovipositional pattern was noted by the sampling of egg rafts along transects and determining larval abundance by the dipping technique. In the second experiment a mixture of Culex stigmatosoma and Culex tarsalis larvae was collected.
在两项重复的田间实验中，确定了幼虫栖息地的有机富集对蚊子产卵的影响。在第一项研究中，尖音库蚊和致倦库蚊的产卵量（以早期龄期幼虫数量衡量）在洪水过后不久达到最大峰值，然后下降到显著更低的平衡水平。一组后来添加了补充有机物的池塘，在添加额外有机物后不久产卵量显著增加。在第二项实验中，通过沿样带对卵块进行采样并用浸渍技术确定幼虫丰度，观察到了类似的产卵模式。在第二项实验中，收集到了尖音库蚊和跗斑库蚊幼虫的混合物。
