The study of the biological aspects of spp., strengthens the entomological surveillance.
To determine biological aspects and behavior of adult mosquitoes in the urban area of Puerto Carreño municipality, Vichada, Colombia.
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 Carreño. The biting rate activity, the natural infection by and 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.
In order of abundance the species found were i (n=1,166), (n=152), (n=59), F (n=25), (n=16), (n=3) and (n=2). 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 VK210 and its annual entomological inoculation rate was 2. Natural infection of with 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.
Transmission of malaria in the urban area of Puerto Carreño, Vichada, can occur by and s. s.
对疟蚊属物种生物学特性的研究有助于加强昆虫学监测。
确定哥伦比亚比查达省卡雷尼奥港市区成年疟蚊的生物学特性及行为。
在卡雷尼奥港市区，连续8个月，每月选取两个连续夜晚，于18:00至06:00期间，每小时采集50分钟落在室内和室外人体上的野生按蚊。测定每种按蚊的叮咬率活动、使用酶联免疫吸附测定法检测间日疟原虫和恶性疟原虫VK247及VK210的自然感染情况，以及年昆虫学接种率。通过聚合酶链反应扩增白色基因来确定阿尔比塔西斯复合体的成员。
按数量多少排序，发现的物种依次为i（n = 1166）、（n = 152）、（n = 59）、F（n = 25）、（n = 16）、（n = 3）和（n = 2）。在室外，于21:00至22:00以及05:00至06:00出现两个活动高峰；在室内，于21:00至22:00以及04:00至05:00出现两个活动高峰。该物种被检测出感染恶性疟原虫VK210，其年昆虫学接种率为2。检测出感染间日疟原虫，年昆虫学接种率为5，在室内和室外18:00至19:00期间出现叮咬活动高峰。
在比查达省卡雷尼奥港市区，间日疟原虫和恶性疟原虫可通过特定按蚊传播。
