Larval ecology is an important aspect of the population dynamics of anopheline mosquitoes (Diptera: Culicidae), the vectors of malaria. Anopheles larvae live in pools of stagnant water and adult fitness may be correlated with the nutritional conditions under which larvae develop. A study was conducted in Mbita, Western Kenya, to investigate how properties of the soil substrate of Anopheles gambiae breeding pools can influence development of this mosquito species. An. gambiae eggs from an established colony were dispensed into experimental plastic troughs containing soil samples from a range of natural Anopheles larval habitats and filtered Lake Victoria water. The duration of larval development (8-15 days), pupation rate (0-79%), and adult body size (20.28-26.91 mm3) varied among different soil types. The total organic matter (3.61-21.25%), organic carbon (0.63-7.18%), and total nitrogen (0.06-0.58%) levels of the soils were positively correlated with pupation rate and negatively correlated with development time and adult body size.
幼虫生态学是疟蚊（双翅目：蚊科）种群动态的一个重要方面，疟蚊是疟疾的传播媒介。冈比亚按蚊幼虫生活在积水池中，而成蚊的健康状况可能与幼虫发育时的营养条件相关。在肯尼亚西部的姆比塔进行了一项研究，以调查冈比亚按蚊繁殖池土壤基质的特性如何影响这种蚊子的发育。将来自一个已建立种群的冈比亚按蚊卵放入装有一系列天然按蚊幼虫栖息地土壤样本和过滤后的维多利亚湖水的实验塑料槽中。幼虫发育持续时间（8 - 15天）、化蛹率（0 - 79%）和成蚊体型（20.28 - 26.91立方毫米）在不同土壤类型中有所不同。土壤中的总有机质（3.61 - 21.25%）、有机碳（0.63 - 7.18%）和总氮（0.06 - 0.58%）水平与化蛹率呈正相关，与发育时间和成蚊体型呈负相关。
