Dengue fever has become the most important vector-borne viral disease in Brazil. Human facilitated transport of desiccation-resistant eggs has led to its two most important vectors, Aedes aegypti and Ae. albopictus, becoming widespread. In this paper, we report seasonal and spatial variation in larval abundances of Ae. aegypti and Ae. albopictus across a small-scale transition zone between an urban area and an urban wooded/forested area within Rio de Janeiro, Brazil. We installed 400 ovitraps across 10 sites with different human population densities and vegetation coverage. Eggs and larvae were collected for three weeks during the wet and dry seasons of 2002 and 2003. Ae. albopictus was predominantly found in the forested areas of the study site whereas in the urbanized area Ae. aegypti was more abundant. Both species peaked during the wet season. This distribution pattern, which may reflect adult flight range, may favor the co-occurrence of larvae of these species in a small-scale urban/urban forest transition zone.

“…Several authors have studied larval competition between A. aegypti and A. albopictus , and A. albopictus is known to have a greater dispersal capability to more undisturbed habitats. Therefore, A. albopictus is able to reach forest margins, while A. aegypti is restricted to urban areas (Ho et al 1989, Rai 1991, Lima-Camara et al 2006.…”

This study evaluates the importance of native bromeliads growing on rocky outcrops interspersed with urbanized areas as breeding sites for the Aedes aegypti (L.) in Vitória, state of Espírito Santo, Brazil. Oviposition traps were installed in backyards of houses in two separate zones. In the irst zone houses were up to 50 m away from the rocky outcrops, while in the second zone they were at least at 200 m from the rocky outcrops. Aedes aegypti was signi icantly more abundant in the latter zone. The inding was that rocky outcrops with native bromeliads, even with the greater availability of potential breeding sites, do not play an important role as breeding sites for A. aegypti. This conclusion supports the hypothesis that the macrobiota of native bromeliads plays an important role in the natural control of A. aegypti. Besides, the interspeci ic competition between species of mosquitoes and the attractiveness of bromeliads could also be important factors. Introducti onThe African mosquito Aedes aegypti (L.) became adapted to arti icial breeding habitats, accompanying human migrations throughout the tropics and subtropics (Barrett & Higgs 2007). Its preferred breeding sites include arti icial containers that allow rainwater to accumulate, particularly in areas of high human population density (Mazine et al 1996). In Brazil, A. aegypti acted as the vector of urban yellow fever in recent decades, and has also been responsible for dengue fever epidemics (Vasconcelos 2002, Braga 2007. Various researchers have reported inding immatures of this species in bromeliads used for urban ornamentation, leading public health authorities to discourage maintenance of these plants in residential areas (e.g. Forattini & Marques 2000, Cunha et al 2002. Aedes aegypti were also reported in native bromeliads growing on rocky outcrops interspersed with urbanized areas in Vitória, state of Espírito Santo, Brazil (Varejão et al 2005). Therefore, the objective of the present study was to evaluate whether native bromeliads in their natural habitat represent important breeding sites for A. aegypti. Bromeliads and the human-produced breeding sites in residences close to rocky outcrops would be readily available and more exposed to infestation by A. aegypti than those situated at greater distances from these rocky outcrops, if bromeliads prove to be playing an important role as breeding sites for this species. Material and MethodsThe study was carried out in the Vitória neighborhoods of Santa Lúcia and Bela Vista (Fig 1), where A. aegypti had already been reported breeding in native bromeliads Billbergia amoena, Billbergia tweedieana, and Vriesea extensa (Varejão et al 2005). The climate of the region is de ined by the Köppen-Geiger classi ication as tropical monsoon (Peel et al 2007), with a mean annual temperature of 25ºC and an annual precipitation of 1100 . Five surveys were conducted between 2007 and 2008, when ovitraps were simultaneously installed in the selected houses every three months. These traps remained exposed for ive da...

“…En algunos países de Latinoamérica, como Brasil y Cuba, la especie se ha hallado en áreas rurales (14,15), y también en el territorio indígena del estado Bolívar de Venezuela, lo cual constituye una alarma ante el riesgo de introducción del dengue en áreas selváticas ya que podría tener graves efectos en la salud de la población indígena (16).…”

Editorial Aedes aegypti en el área rural: implicaciones en salud públicaEl mosquito Aedes aegypti (L) es considerado como el vector primario de los virus del dengue, del chikungunya, del zika y de la fiebre amarilla urbana en el continente americano (1). La especie también ha sido incriminada como posible vector urbano de la encefalitis equina venezolana (2). El papel de A. aegypti como transmisor de enfermedades al hombre fue demostrado por el médico estadounidense Walter Reed en 1901, confirmando la hipótesis planteada por el médico cubano Carlos Finlay en el sentido de que A. aegypti era el vector de la fiebre amarilla (3).Este mosquito es originario de África, en donde su forma ancestral se desarrollaba en huecos de árboles, y las hembras del mosquito presentaban hábitos zoofílicos (4). Según Gast-Galvis (5), el insecto fue introducido al continente americano en los barcos que transportaban esclavos y atracaban en las costas americanas durante la época de la Conquista y la Colonia, y allí adquirió hábitos domésticos, desarrollándose fundamentalmente en depósitos artificiales fabricados por el hombre, aunque también en depósitos naturales en áreas urbanas.Aedes aegypti penetró al interior del país desde Cartagena cuando se estableció la navegación por el río Magdalena, y la especie se detectó en Neiva (Huila) en 1880, en Bucaramanga (Santander) en 1906 y en El Socorro (Santander) en 1929, lugar en donde ocurrió la última epidemia de fiebre amarilla urbana en el país. Para 1949, el mosquito ya se encontraba en la Costa Atlántica, en Buenaventura y en los valles de los ríos Magdalena y Cauca. En 1950 se inició una agresiva campaña de eliminación de A. aegypti en el país en el marco del plan continental de erradicación de A. aegypti en las Américas (5), y el país permaneció libre del mosquito entre 1961 y 1967, excepto en la ciudad de Cúcuta, hecho que, conjuntamente con el deterioro y descuido en las actividades de vigilancia del vector, probablemente contribuyó a la reinfestación de la costa norte colombiana a partir de 1968. Para 1997, el vector se encontraba en 29 departamentos del país, con excepción de Amazonas, Vaupés y Guainía (6), y en el 2010, ya se registraba en todo el país, generalmente en áreas urbanas por debajo de los 1.800 msnm (7), aunque fue detectado a 2.200 msnm en Málaga (Santander) (8) y, recientemente, en zona rural del municipio de Bello (Antioquia) a 2.302 msnm, el registro de mayor altitud para este insecto en Colombia hasta el momento (9).
