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...

“…Regarding Culicinae subfamily, studies mainly have focus in Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Varejão et al 2005, Mendonça et al 2011) and the knowledge on the occurrence of species belonging to this subfamily in wild environment is scarce (Deane et al 1968, Alencar et al 2004. Therefore, studies on the Culicidae fauna in Espírito Santo wild areas, mainly in flat areas, should be encouraged.…”

Mosquitoes comprehend a group with a major impact on public health, because some species transmit parasites vertebrate hosts. Comparative studies between preserved environment and disturbed areas provide important epidemiological information, due to the major knowledge on species populational dynamics and the possibility of a contact between vector species and human population. This work aims to characterize and compare the fauna of mosquitoes in the Goytacazes National Forest (GNF) and surrounding area, in the State of Espírito Santo, in Brazil. Collections occurred simultaneously in a preserved environment and in a peridomicile, from 15:00 to 18:00, between July 2008 and May 2009. In each environment, it was used a modified trap of Shannon type. As a result, 1,490 specimens from 14 genera and 19 identified species were collected. The species diversity (H = 1.95), species richness (S = 17), equitability index (J = 0.68) and the number of collected specimens (n = 1,100) were higher in the forest environment. The plentiful species were respectively Aedes (Ochlerotatus) scapularis (Rondani, 1848), Culex (Culex) nigripalpus Theobald, 1901 and Aedes (Ochlerotatus) fulvus (Wiedemann, 1828). Our results demonstrate that the occurrence of vector species in this region increases the potential risk of diverse arboviruses occurrence, especially wild-type yellow fever.

The efficiency of an alternative method of collection (by suction of water) for the study of Culicidae and Chironomidae (Diptera), Scirtidae (Coleoptera) and Coenagrionidae (Odonata) in bromeliads with different foliar architecture in a restinga at Florianópolis, SC, Brazil, was studied. The alternative method was less efficient to collect Culicidae and Chironomidae (Wilcoxon test p < 0.05) and was more efficient to Scirtidae and Coenagrionidae (Wilcoxon test p > 0.05) from Aechmea lindenii. This method was less efficient to collect insects of all groups from Vriesea friburgensis (Wilcoxon test p < 0.05). The alternative method was efficient to estimate the diversity of these insects in both species of bromeliads. The higher mobility of immature forms of beetles and dragonflies, and the availability of only one tank in Aechmea lindenii, contrasting to several tanks in Vriesea friburgensis that help the suction of these immature, probably influenced the results, which indicated that the suction method should not replace the dismantling in the study of Culicidae and Chironomidae. This method can be useful to get immature forms of Scirtidae and Coenagrionidae in one-tank bromeliads.
