“…It generally breeds in large artificial containers, has high daily survival rates, and moves across variable distances depending on the environment and climate, while its populations are highly genetically structured 3,4,5,6,7,8 . Differences in the degree of urbanization and in socio-economic status between adjacent blocks mean that Rio de Janeiro is a mosaic in terms of dengue epidemiology, where specific control activities for each area might be required 4,9,10 .…”

Population size and daily survival rates of disease vectors are important determinants of vectorial capacity. A mark-release-recapture experiment was conducted in a dengue endemic urban neighborhood of Rio de Janeiro, Brazil, to estimate population size, survival rate and vectorial capacity of Aedes aegypti females using back-pack aspirators and gravid sticky traps (MosquiTRAP). Estimations of the gravid female population size were different when using data gathered from just the MosquiTRAP (3,505 individuals) or aspirator (1,470). However Ae. aegypti survival rates and longevity were similar irrespective of the method of capture. Up to 26.3% of released females would be able to survive for more than 10 days, the length of time of the extrinsic incubation period. Vectorial capacity value ranged between 0.01567 and 0.4215 and the basic reproductive number (R0) was estimated to be between 0.0695 and 1.88.

“…This species has synanthropic behavior and usually occupies anthropic areas (Forattini 2002). In urban areas, it usually breeds in discarded recipients; however, studies show that this species uses natural breeding sites in urban and rural areas with a great variety of microorganisms and organic matter for the development of its immature forms, such as domesticated bromeliads whether or not they are used for decorative purposes (Cunha et al 2002, Delgado & Machado-Allison 2006, Gonçalves & Messias 2008.…”

The community of Diptera (Insecta) colonizing axils of Alocasia macrorrhizos (L.) G.Don (Araceae), with records of Aedes aegypti (L.) and Aedes albopictus (Skuse) in urban areas of Manaus, Amazonas

Alocasia macrorrhizos (L.) G.Don grows and proliferates in shaded areas in several forest fragments in urban zones. The adult plant has axils that accumulate rain water (phytotelmata) and serve as breeding sites for several families of aquatic insects. The objective of this study was to determine the composition of the entomofauna associated with water accumulations in axils of A. macrorrhizos in urban areas of Manaus, Brazil. Individuals of A. macrorrhizos were sampled in five forest fragments, between April/2005 and March/2007 in urban areas of Manaus, totaling 184 sampling units. A manual suction hose was used for the removal of entomofauna. A total of 1,941 immatures of Diptera were collected representing the following families: Culicidae (96.5%), Chironomidae (2%), Psychodidae (0.7%), Ephydridae (0.7%) and Corethrellidae (0.1%). Five Culicidae species were identified: Wyeomyia melanocephala Dyar & Knab, 1906 (91.7%), Wy. ypsipola Dyar, 1922 (4.3%), Aedes albopictus (Skuse, 1894) (2.3%), Ae. aegypti (Linnaeus, 1762) (1.5%) and Johnbelkinia longipes (Fabricius, 1805) (0.1%). The members of Culicidae were the most abundant, confirming the importance of this group in communities associated with phytotelmata, with a positive relation to the volume of water (p < 0.05). The occurrence of Ae. aegypti and Ae. albopictus in axils of A. macrorrhizos demonstrates the potential of this Araceae as a breeding site of these medically important species. However, the real contribution of this Araceae in the maintenance and dispersion of populations of these two species of mosquitoes throughout the year should be further studied.

“…Since then, various researchers found the presence of this species in bromeliads cultivated in households, drawing attention to the risk that these plants could pose as additional breeding sites for this and other mosquito species (e.g. Forattini & Marques 2000, Cunha et al 2002. In French Guiana, A. aegypti was found in bromeliads in the rainforests at distances of about 30 km from the nearest human settlement (Fouque et al 2004), and in Brazil it was reported in native bromeliads growing on rocky outcrops in the urbanized areas of Vitória (Varejão et al 2005).…”

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...
