Aedes aegypti is a vector for the dengue virus in Colombia. Its productivity can be estimated using pupal counts.
To determine Ae. aegypti productivity in households and public spaces in Girardot (Colombia) during both wet and dry seasons.
The amount of Ae. aegypti pupae was evaluated in 20 randomly selected clusters in Girardot, each consisting of 100 households and public spaces. Inspections were performed during the rainy (February-May, 2011), and dry (August-September, 2011) seasons. House, container, Breteau, person and hectare pupae indices were estimated.
During the rainy season households contributed 94% to the total number of pupae (n=7,098) while only 6% (n=482) were found in public spaces. In the dry season, 98% (n=9,138) of pupae were found in households and 2% (n=223), in public spaces. Low water-storage tanks and tanks for washing purposes provided >87% of pupae in households, whereas jars, tires and sinks contained most pupae in public spaces. High pupal densities were observed in public spaces during the rainy season and in streets and schools in the dry season. There were no significant differences in the index per person (rainy season=1.0; dry season=1.3) or per hectare (rainy season=0.96, dry season=0.45) between seasons.
High Ae. aegypti pupal densities were found inside households in low water-storage tanks and tanks for washing purposes during both the dry and rainy seasons. Public spaces provided more aquatic habitats during the rainy season. Vector control strategies targeting these containers could allow a more rational use of resources and increase efficiency.
埃及伊蚊是哥伦比亚登革热病毒的传播媒介。其繁殖率可通过蛹计数来估算。
确定哥伦比亚吉拉尔多市雨季和旱季家庭及公共场所的埃及伊蚊繁殖率。
在吉拉尔多市随机选取20个群组，每个群组由100户家庭和公共场所组成，评估埃及伊蚊蛹的数量。在雨季（2011年2月至5月）和旱季（2011年8月至9月）进行检查。估算房屋、容器、布雷托、人均和每公顷蛹指数。
雨季期间，家庭贡献了蛹总数的94%（n = 7098），而公共场所仅占6%（n = 482）。旱季，98%（n = 9138）的蛹出现在家庭中，2%（n = 223）出现在公共场所。家庭中，低水箱和洗涤用水箱提供了超过87%的蛹，而公共场所中，罐子、轮胎和水槽包含了大部分蛹。雨季在公共场所以及旱季在街道和学校观察到高蛹密度。两季之间人均指数（雨季 = 1.0；旱季 = 1.3）或每公顷指数（雨季 = 0.96，旱季 = 0.45）无显著差异。
旱季和雨季期间，家庭内低水箱和洗涤用水箱中埃及伊蚊蛹密度较高。雨季公共场所提供了更多水生栖息地。针对这些容器的病媒控制策略可使资源得到更合理利用并提高效率。
