Surveys were conducted in three neighbourhoods of Barranquilla, the main seaport of Colombia, to identify, using counts of pupae in water containers during the wet and dry seasons, the most productive Aedes aegypti breeding sites. Overall, 3,433 premises were investigated in the wet season and 3,563 in the dry, representing, respectively, 82.3% and 84.6% of the total numbers of premises in the study areas. Despite a reasonably reliable supply of piped water, there were still some large storage containers for domestic water (cement ground tanks and plastic, metal and cement drums) in the area. Although such containers represented only 1.8%-16.3% of the total number of containers observed, they contributed 72.0%-78.2% and 65.0%-95.8% of the total Ae. aegypti pupal population in the three study neighbourhoods during the wet and dry seasons, respectively. In contrast, bottles represented 23.0%-88.9% of the total number of containers but produced no more than 0.1% of the total Ae aegypti pupal populations in these neighbourhoods. Other containers (tyres, vases, 'other discarded' and 'other used') generally produced only low numbers of pupae. In some settings, however, containers in the 'other discarded' category could contribute up to 19% of the total pupal population, and in one survey of one neighbourhood a single container in this category held 9.1% of all the pupae collected. These results, from a city where dengue fever is endemic, will help to focus local campaigns for Ae. aegypti source-reduction on the most productive categories of container.
在哥伦比亚主要海港巴兰基亚的三个社区进行了调查，通过在雨季和旱季对水容器中的蛹进行计数，以确定埃及伊蚊繁殖最活跃的场所。总体而言，雨季调查了3433处房产，旱季调查了3563处，分别占研究区域内房产总数的82.3%和84.6%。尽管有合理可靠的自来水供应，但该地区仍有一些用于储存生活用水的大型容器（水泥地水箱以及塑料、金属和水泥桶）。虽然这些容器仅占观察到的容器总数的1.8%-16.3%，但在雨季和旱季，它们分别占三个研究社区埃及伊蚊蛹总数的72.0%-78.2%和65.0%-95.8%。相比之下，瓶子占容器总数的23.0%-88.9%，但在这些社区产生的埃及伊蚊蛹总数不超过0.1%。其他容器（轮胎、花瓶、“其他丢弃物”和“其他用品”）通常产生的蛹数量较少。然而，在某些情况下，“其他丢弃物”类别的容器可贡献高达蛹总数的19%，在对一个社区的一次调查中，该类别中的一个容器容纳了所收集蛹总数的9.1%。这些来自登革热流行城市的数据，将有助于集中开展针对埃及伊蚊的本地防控活动，重点减少最易滋生蚊虫的容器种类。
