Because the role of Aedes albopictus as an incriminated vector of several viral pathogens, its control is important to human health. To establish appropriate control methods, characterization of the larval habitats is a necessary first step.
Habitats of the immature stages of Ae. albopictus were characterized with respect to physical-chemical parameters and by floral and faunal arrays present.
Leticia is located at the southernmost tip of Colombia on the banks of the Amazon River. In the urban area, 154 houses were inspected in December 2002 and January 2003. Physical-chemical data were collected, including exposure to sunlight, location, container size and material, water conductivity, and dissolved oxygen. Macroinvertebrates and plankton samples were taken at each positive larval site. The results were compared using descriptive analysis, principal component analysis, classification dendrograms, and diversity indexes.
Twenty-one habitats were found positive for Diptera, and 13 were positive for Ae. albopictus larvae. Most of the positive habitats (92%) were located near the houses--they were small or medium size receptacles located in the shade. This water generally had low conductivity and low turbidity, although high values of these parameters were also identified. The habitats had low diversity indexes for macroinvertebrates and high diversity indexes for plankton. In the principal component analysis, significant correlation was found with mites, oligochaetes and hemipterans (the macroinvertebrates) and with bacilarophyceaes, clorophyceaes and cianophyceas (the algal forms).
In Leticia, females of Ae. albopictus were found in newly established habitats with sufficient availability of resources, low conductivity, and turbidity, lower intra-and interspecific competition.
由于白纹伊蚊是多种病毒病原体的公认传播媒介，对其进行控制对人类健康至关重要。为了建立适当的控制方法，描述幼虫栖息地特征是必要的第一步。
对白纹伊蚊未成熟阶段的栖息地进行物理化学参数以及现存动植物群落特征描述。
莱蒂西亚位于哥伦比亚最南端的亚马逊河岸。2002年12月和2003年1月，对市区154所房屋进行了检查。收集了物理化学数据，包括日照情况、位置、容器大小和材质、水电导率和溶解氧。在每个有幼虫的阳性地点采集大型无脊椎动物和浮游生物样本。使用描述性分析、主成分分析、分类树状图和多样性指数对结果进行比较。
发现21个栖息地有双翅目阳性，13个栖息地有白纹伊蚊幼虫阳性。大多数阳性栖息地（92%）位于房屋附近，是位于阴凉处的中小型容器。这些水体的电导率和浊度通常较低，不过也发现了这些参数的高值情况。这些栖息地的大型无脊椎动物多样性指数较低，浮游生物多样性指数较高。在主成分分析中，发现与螨类、寡毛类和半翅目（大型无脊椎动物）以及与硅藻、绿藻和蓝藻（藻类形式）有显著相关性。
在莱蒂西亚，在资源充足、电导率和浊度低、种内和种间竞争较小的新形成的栖息地发现了白纹伊蚊雌蚊。
