The establishment of habitats for immature Ae. aegypti is regulated by biotic and abiotic factors and interactions between these factors. This study aimed to determine the effects of physico-chemical variables and planktonic algae on immature Ae. aegypti habitats in 101 water tanks (50 of them containing Ae. aegypti pupae and/or larvae) in Girardot, Colombia. Physical data were collected from the water tanks (volume, capacity, material, detritus, and location), along with the physico-chemical variables (temperature, pH, conductivity, redox potential, dissolved oxygen, percentage of oxygen saturation, nitrates, nitrites, and orthophosphates). The richness and abundance of the planktonic organisms were also measured. A chi-square test showed that the occurrence of detritus was greater and the container volume was smaller in the tanks that were positive for larvae. Only Cyanobacteria had a positive correlation with the abundance of immature-stage Ae. aegypti. The results could be important for understanding the vector ecology and envisaging its probable control in the domestic water tanks of Girardot.
未成熟埃及伊蚊栖息地的建立受生物和非生物因素以及这些因素之间相互作用的调节。本研究旨在确定理化变量和浮游藻类对哥伦比亚吉拉尔多101个水箱中未成熟埃及伊蚊栖息地的影响（其中50个水箱中有埃及伊蚊蛹和/或幼虫）。从水箱收集了物理数据（体积、容量、材质、碎屑和位置），以及理化变量（温度、pH值、电导率、氧化还原电位、溶解氧、氧饱和度百分比、硝酸盐、亚硝酸盐和正磷酸盐）。还测量了浮游生物的丰富度和丰度。卡方检验表明，幼虫呈阳性的水箱中碎屑的出现率更高，而容器体积更小。只有蓝藻与未成熟阶段埃及伊蚊的丰度呈正相关。这些结果对于理解病媒生态学以及设想在吉拉尔多家庭水箱中对其进行可能的控制可能具有重要意义。
