几年来，在哥伦比亚，Urabá-Bajo考卡和阿尔托Sinú地区是该国疟疾病例最多的地区。疟疾病媒的定罪和昆虫学参数的表征将有助于更好地了解该地区的疟疾传播动态和设计有效的病媒控制策略。2008年11月至2010年6月期间，我们对哥伦比亚主要疟疾流行地区Urabá-Bajo考卡和Alto Sinú的三个地区（La Capilla、Juan Jose和El Loro）进行了纵向调查，量化昆虫学（丰富度和叮咬活动）和传播参数，包括感染率（IR）和昆虫学接种率（EIR），以确定潜在的疟蚊媒介。共采集按蚊7种5316只。以努氏按蚊（69.5%）和达林按蚊（22.2%）数量最多，其次为伪喙按蚊（4.5%）、阿尔比特按蚊（2%）、西北三环按蚊（1.8%）、点状按蚊和银纹按蚊（均< 1%）。其中3种自然感染间日疟原虫；nuneztovari,。darlingi （IRs < 1%）和An。triannulatus （IR = 1.5%）。这些物种的年感染叮咬率为每年3.5至4.8次。这些结果表明，安。nuneztovari和An。达林蝇仍然是本地区最重要的疟疾病媒。在其他南美国家发现一种具有地方重要性的三环按蚊自然感染间日疟原虫VK247；因此，应进一步开展工作，以了解该物种是否在该地区的疟疾传播中发挥作用。
In Colombia for several years, the Urabá-Bajo Cauca and Alto Sinú region has registered the highest numbers of malaria cases in the country. Malaria vector incrimination and the characterization of entomological parameters will allow for a better understanding of malaria transmission dynamics and the design of effective vector control strategies for this region. We conducted a longitudinal survey between November 2008 and June 2010 to quantify entomological (abundance and biting activity) and transmission parameters, including infection rate (IR) and entomological inoculation rate (EIR), to incriminate potential anopheline vectors in three localities of a major Colombian malaria endemic region, the Urabá-Bajo Cauca and Alto Sinú: La Capilla, Juan Jose and El Loro. A total of 5,316 anopheline mosquitoes corresponding to seven species were collected. Anopheles nuneztovari (69.5%) and Anopheles darlingi (22.2%) were the most abundant species, followed by Anopheles pseudopunctipennis (4.5%), Anopheles albitarsis s.l. (2%), Anopheles triannulatus lineage Northwest (1.8%), Anopheles punctimacula and Anopheles argyritarsis (at < 1%, each). Three species were naturally infected with Plasmodium vivax, An. nuneztovari, An. darlingi (IRs < 1%) and An. triannulatus (IR = 1.5%). Annual EIRs for these species ranged from 3.5 to 4.8 infective bites per year. These results indicate that An. nuneztovari and An. darlingi continue to be the most important malaria vectors in this region. Anopheles triannulatus, a species of local importance in other South American countries was found naturally infected with Plasmodium vivax VK247; therefore, further work should be directed to understand if this species has a role in malaria transmission in this region.
