Yellow fever is a serious illness public health importance and is transmitted by mosquitoes of the genera Haemagogus and Sabethes in the rural and forest environments, and by Aedes aegypti in the urban setting. In Colombia, Haemagogus janthinomys and H. equinus are considered efficient vectors of this viral disease.
The presence of the mosquito Haemagogus equinus was recorded over an 8 year period, in the periurban areas of the Soledad and Malambo municipalities (Atlantico Province) of northern Colombia.
The data was obtained from records of the entomological collections from two collection sites: (1) 14 larva traps located at the Erneasto Cortissoz airport in the municipality of Soledad between 1997--2005 and (2) 10 larva traps located at Vergara and Velasco Batallion in the municipality of Malambo in 2005.
Haemogogus equinus was reported for the first time in Soledad in 1998. In the following 8 years, 197 larvae were reported. The individuals were found sharing the trap with Aedes aegypti, Culex nigripalpus and Uranotaenia lowii. In Malambo, the first discovery of H.equinus occurred in 2005, with a total of 641 larvae. No other Culicidae were associated with it.
The presence of H. equinus in larvitraps located near the urban zone, shows adaptation to the use of artificial containers as larval habitats, Urbanization of this species in zones with a high Ae. aegypti infestation index increases the potential introduction of sylvan yellow fever virus and constitutes a risk for re-emergence of urban cycles of yellow fever.
黄热病是一种具有重要公共卫生意义的严重疾病,在农村和森林环境中由嗜血蚊属和萨氏蚊属的蚊子传播,在城市环境中由埃及伊蚊传播。在哥伦比亚,詹氏嗜血蚊和马氏嗜血蚊被认为是这种病毒性疾病的有效传播媒介。
记录哥伦比亚北部大西洋省索莱达德和马拉姆博市城郊地区8年间马氏嗜血蚊的存在情况。
数据来自两个收集地点的昆虫学收集记录:(1)1997年至2005年期间位于索莱达德市埃尔内斯托·科尔蒂索斯机场的14个幼虫诱捕器,以及(2)2005年位于马拉姆博市韦尔加拉和贝拉斯科营的10个幼虫诱捕器。
1998年在索莱达德首次报告发现马氏嗜血蚊。在随后的8年里,报告了197只幼虫。发现这些个体与埃及伊蚊、黑足库蚊和罗氏蓝带蚊共用诱捕器。在马拉姆博,2005年首次发现马氏嗜血蚊,共有641只幼虫。未发现其他蚊科与之相关。
在城市区域附近的幼虫诱捕器中发现马氏嗜血蚊,表明其适应使用人工容器作为幼虫栖息地。在埃及伊蚊感染指数高的地区,该物种的城市化增加了森林黄热病毒潜在引入的可能性,并构成黄热病城市传播周期再次出现的风险。
