The study of the landscape ecology, biological microhabitat, and epidemiological implications for the distribution of the main vectors Aedes aegypti and Aedes albopictus contribute to the prevention and control actions regarding the diseases they transmit.
This study sought to assess data on positive properties of the vector control program activities from 1998 to 2010. An entomological survey was also carried out on a sample of buildings collecting larvae and pupae from containers between October and April (spring / summer) from 2002 to 2005. We assessed the physico-chemical data of the water in 20% of positive containers. The vegetation and urbanization were assessed with the aid of satellite images and microenvironments were classified as urbanized, woods, and shrubs. The data were analyzed using statistical and geoprocessing software.
Ae. aegypti and Ae. albopictus colonized all types of microhabitats and microenvironments, predominantly in the urbanized area, in isolation and in coexistence. The microhabitat of Ae. aegypti showed a temperature gradient greater than that of Ae. albopictus, and there was an association with urbanized areas for the first species and wooded areas for the last species.
Landscape ecology and intra-urban differences favor different microclimates, which contribute to the coexistence of species in the urban environment in an area close to the forest, raising the risk of other arbovirus infections in urban areas. The ecological niche should be considered for Ae. albopictus. Entomological and virologic monitoring are suggested as arbovirus surveillance actions in urban infested centers near preserved forests.
对景观生态学、生物小生境以及主要病媒埃及伊蚊和白纹伊蚊分布的流行病学意义的研究有助于预防和控制这些病媒传播的疾病。
本研究旨在评估 1998 年至 2010 年期间病媒控制计划活动的阳性特性数据。还于 2002 年至 2005 年期间在 10 月至 4 月（春季/夏季）对建筑物样本进行了蚊虫调查，从容器中收集幼虫和蛹。我们评估了 20%阳性容器中水中的理化数据。利用卫星图像评估了植被和城市化情况，并将微环境分为城市化、林地和灌木丛。使用统计和地理处理软件分析数据。
埃及伊蚊和白纹伊蚊已在所有类型的小生境和微环境中定殖，主要在城市化地区，孤立或共存。埃及伊蚊的小生境的温度梯度大于白纹伊蚊，并且与城市地区的第一物种和林区的最后一个物种有关。
景观生态学和城市内部差异有利于不同的小气候，这有助于在靠近森林的城市环境中共同存在物种，增加了城市地区感染其他虫媒病毒的风险。生态位应考虑白纹伊蚊。建议进行昆虫学和病毒学监测，作为城市受感染中心靠近保护区森林的虫媒病毒监测行动。
