“…Within the Diptera species sampled, two belonged to the Culicidae family. Several species of this family are vectors of diseases and use the water reservoir as natural breeding sites (Pittendrigh, 1948;Forattini et al, 1998;Forattini and Marques, 2000). Together with species of Chironomidae, the Culicidae are the most common organisms in phytotelmata (Fish, 1983).…”

Relationship between invertebrate fauna and bromeliad size

et al. 2007

Several bromeliads species store water and organic substrates, allowing the establishment of phytotelmata and associated fauna on their leaves. In this study, we sampled 70 individuals of Vriesea sp. (Carrière) (Bromeliaceae), in rupestrian fields in the Serra de Ouro Branco-MG, Brazil. The relationships between invertebrate species richness and abundance and size of bromeliads were tested using multiple regression. We found 19 species associated with bromeliads, mainly Diptera larvae. The abundance of the phytotelmate fauna increased principally in relation to the volume of water in the bromeliad reservoir. Phytotelmata richness was affected principally by diameter of the reservoir. There was a significant relationship between the abundance and richness of invertebrates associated with leaves with diameter and height of the plant. Invertebrate richness was better explained by abundance of individuals. These results suggest that the increase of richness was attended by higher numbers of microhabitats and more space for colonization of bigger bromeliads. Additionally, there was more chance of sampling different species in locales with greater abundance of individuals.Keywords: species-area relationship, phytotelmata fauna, insects, Bromeliaceae. Relação entre a fauna de invertebrados e o tamanho da bromélia ResumoMuitas espécies de bromélias são capazes de armazenar água e detritos, permitindo o estabelecimento de comunidades associadas aos seus tanques de água e às suas folhas. Neste trabalho, foram amostrados 70 indivíduos de Vriesea sp. (Carrière) (Bromeliaceae), em uma área de campo rupestre na Serra de Ouro Branco-MG, Brasil. Foi testada a relação entre a riqueza e a abundância das comunidades de invertebrados associados e o tamanho da bromélia. Em todos os casos foram utilizadas análises de regressão linear múltipla. Foram amostradas 19 espécies, principalmente larvas de Diptera associadas à bromélia. A abundância da fauna fitotelmata aumentou principalmente com o volume de água no reservatório da bromélia. Já a riqueza de fitotelmata foi relacionada principalmente com o diâmetro da planta. No entanto, a abundância e riqueza dos invertebrados associados às folhas apresentaram relação significativa com a altura e o diâmetro da planta. A riqueza de invertebrados foi mais bem explicada pela abundância de indivíduos do que pelo tamanho da bromélia. Estes resultados sugerem que o aumento da riqueza pode ter sido resultante do maior número de microhabitats e de espaço para colonização em bromélia de maior tamanho. Além disso, houve maior chance de amostrar espécies diferentes em locais com maior abundância de indivíduos.Palavras-chave: relação espécie-área, fauna fitotelmata, insetos, Bromeliaceae.

“…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...

“…In Brazil, Ae. aegypti has also been collected from bromeliads in gardens (Forattini et al 2000;Mocellin et al 2009) although some authors suggested that those habitats do not contribute to the occurrence of immature stages of the insect (Mocellin et al 2009;Santos et al 2010). Other studies in Argentina have reported tree holes in Aguaray, Salta province (Mangudo et al 2011), axils of Araceae in Puerto Iguazú, Misiones province (Campos et al 2011), and axils of A. distichantha in Iltico and Monte Bello, Tucumán province (Stein et al 2013) as natural habitats for the species.…”

Abstract:We report here three new mosquito records in the Yungas ecoregion [Culex (Culex) dolosus, Culex (Micro culex) Pleuristriatus Series and Howardina sp.] and the expansion of the distributions of 17 species of the genera Anopheles, Culex, Aedes, Psorophora, and Toxorhynchites for Argentina. These findings broaden the total number of species recorded for northwestern Argentina to 174, from which number 57 species are distributed in the Tucumán province, 21 in the Catamarca, and 96 in the Salta. Also included is information on immature instars collected in phytotelmata.
