疟疾媒介按蚊（双翅目：蚊科）在波多黎各卡雷诺市，比查达，哥伦比亚介绍。对按蚊属的生物学方面的研究，加强昆虫监测.研究哥伦比亚维查达省卡雷诺港市城区按蚊成虫的生物学特征和行为。在Puerto Carreno市区连续两个晚上/月，在18：00和06：00之间以50分钟/小时的速度收集了在室内和室外降落在人类身上的野生按蚊，持续8个月。测定了各虫种的叮虫率、自然感染率、年接种率、间日疟原虫VK 247和VK 210的ELISA测定值。通过聚合酶链反应扩增白色基因，确定了该复合体的成员。发现的物种数量依次为安。darlingi（n= 1，166）、南方古猿An. marajoara sensu stricto（n=152），An. braziliensis（n=59）、巴西拟步行虫An. Albitarsis F（n=25），An.宽感白跗按蚊（An. albitarsis lato，n=16）、南方按蚊（An.银跗线螨（n=3）和南方按蚊（An.广义Oswaldoi（n=2）。一个. darlingi在室外21：00 - 22：00和05：00 - 06：00以及室内21：00 - 22：00和04：00 - 05：00之间显示出两个活动高峰。间日疟原虫VK 210对该虫有自然感染，年接种率为2。恶性疟原虫在严丝毛圆线虫中有自然感染，年接种率为5，在18：00 ~ 19：00为室内外叮咬高峰期。在维查达的卡雷尔港城市地区，疟疾的传播可能由安。darlingi和An.马拉霍阿拉湾S.
Anopheles (Diptera: Culicidae) vectors of malaria in Puerto Carreno municipality, Vichada, ColombiaIntroduction. The study of the biological aspects of Anopheles spp., strengthens the entomological surveillance.Objective. To determine biological aspects and behavior of adult Anopheles mosquitoes in the urban area of Puerto Carreno municipality, Vichada, Colombia.Materials and methods. Wild anophelines were collected landing on humans both indoors and outdoors between 18:00h and 06:00h for 50 min/h during two consecutive nights/month for eight months in the urban area of Puerto Carreno. The biting rate activity, the natural infection by Plasmodium falciparum and P. vivax VK247 and VK210 using ELISA, and the annual entomological inoculation rate were determined for each species. The members of the Albitarsis complex were determined by amplificacion of the white gene by polymerase chain reaction.Results. In order of abundance the species found were An. darlingi (n=1,166), An. marajoara sensu stricto (n=152), An. braziliensis (n=59), An. albitarsis F (n=25), An. albitarsis sensu lato (n=16), An. argyritarsis (n=3) and An. oswaldoi sensu lato (n=2). An. darlingi showed two activity peaks between 21:00 to 22:00 and 05:00 to 06:00 hours outdoors and between 21:00 to 22:00 and 04:00 to 05:00 indoors. Natural infection of this species was found with P. vivax VK210 and its annual entomological inoculation rate was 2. Natural infection of An marajoara sensu stricto with P. falciparum was found, with an annual entomological inoculation rate of 5 and a peak biting activity between 18:00 to 19:00 hrs both indoors and outdoors.Conclusion. Transmission of malaria in the urban area of Puerto Carrel:), Vichada, can occur by An. darlingi and An. marajoara s. S.
