| the invasion of urban forest by dengue vectors in rio de janeiro. | the invasion of a secondary forest within the city of rio de janeiro by aedes aegypti and ae. albopictus was evaluated from july 1997 to june 1998 through collections of immature stages in ovitraps set at 1 m, 10 m, 100 m, 500 m, and 1,000 m into the forest from houses on the periphery. both mosquito species were much more abundant close to houses (1-10 m). aedes aegypti was not collected beyond 100 m, while ae. albopictus was the most abundant species overall and in ovitraps at all distances fr ... | 2004 | 15266746 |
| culex mosquitoes in temporary urban rain pools: seasonal dynamics and relation to environmental variables. | the study was conducted in a park of buenos aires city, where a total of 89 rain pools were sampled weekly for mosquito immature stages over a one-year period. the aim of the present paper was to investigate the seasonal dynamics of three culex species breeding in temporary rain pools and to analyze the relationships of the presence of these species to pool dimensions, pool age, vegetation, and insolation degree. the three species showed differences in their seasonal patterns, culex dolosus bein ... | 2004 | 15707296 |
| taxonomic and phylogenetic relationships between species of the genus culex (diptera: culicidae) from brazil inferred from the cytochrome c oxidase i mitochondrial gene. | species of the genus culex linnaeus have been incriminated as the main vectors of lymphatic filariases and are important vectors of arboviruses, including west nile virus. sequences corresponding to a fragment of 478 bp of the cytochrome c oxidase subunit i gene, which includes part of the barcode region, of 37 individuals of 17 species of genus culex were generated to establish relationships among five subgenera, culex, phenacomyia, melanoconion, microculex, and carrollia, and one species of th ... | 2011 | 21485362 |
| community structure of ground-water breeding mosquitoes driven by land use in a temperate wetland of argentina. | wetlands have traditionally been associated with harbouring mosquitoes, but the effect of the land use on their communities has not been thoroughly studied. we characterized the ground-water habitat availability and mosquito species richness and composition during a year-round survey in the predominant land uses (domestic areas, salicaceae plantations, secondary forests and scirpus giganteus marshes) of the paraná lower delta, argentina. each land use presented a characteristically different num ... | 2011 | 21550332 |
| immature mosquitoes from groundwater habitats in a temperate wetland of argentina: environmental associations and seasonal variation of community attributes. | we studied the seasonal patterns of 3 community attributes (breeding site index, richness, and diversity) of groundwater mosquito immatures and their associations with meso- and microhabitat factors in the parana lower delta, argentina, from december 2009 to november 2010. monthly collections at 4 sites yielded 2,313 mosquito immatures, belonging to 19 species assigned to 6 genera. immatures developed in a wide range of microenvironmental conditions (water temperature 4.0-30.2 degrees c, ph 5.4- ... | 2012 | 23833894 |
| host range of the parasite strelkovimermis spiculatus (nematoda: mermithidae) in argentina mosquitoes. | strelkovimermis spiculatus (poinar and camino 1986) is a nematode parasite of mosquitoes isolated from the neotropical region. we investigated the host range of this parasite in mosquito populations for a better understanding of the dynamics of temporary breeding sites. five grassy-pool habitats filled by rainwater were sampled from the summer 2007 through the fall 2008. eight mosquito species were collected: anopheles albitarsis, culex chidesteri, culex dolosus, culex maxi, aedes albifasciatus, ... | 2013 | 23701609 |
| immature mosquitoes associated with urban parklands: implications for water and mosquito management. | the aim of the present study was to compare 2 urban habitat types: pools artificially filled with water from damaged or leaking water pipes (af) and pools naturally filled by rainwater (nf), with regard to their favorability as breeding sites for mosquitoes. two study areas were analyzed, 1 for 5 months and the other for 9 months, covering the whole period when af pools contained water. the af pools held water during the entire study, and showed lower fluctuations in surface area than nf pools. ... | 2013 | 23687852 |
| environmental predictors of the occurrence of ground water mosquito immatures in the paraná lower delta, argentina. | characterizing mosquito larval habitats is essential for understanding the complex interactions between immatures and the biotic and abiotic components of their environment. using generalized linear mixed models, we studied the environmental predictors of the presence of three ubiquitous mosquito species breeding in ground water habitats in the paraná lower delta, argentina. during a year-round survey, 34.1% of the 419 ground water habitats inspected were positive for either culex dolosus s.l. ( ... | 2011 | 21936317 |
| horizontal transmission of amblyospora dolosi (microsporidia: amblyosporidae) to the copepod metacyclops mendocinus (wierzejski, 1892) | this study documents the involvement of a copepod intermediate host in the life cycle of amblyospora dolosi from the neotropical mosquito culex dolosus in argentina. meiospores of a. dolosi from the mosquito host were infectious per os to female adults of the copepod metacyclops mendocinus. all developmental stages in the copepod were haplophasic (unpaired nuclei), with sporulation producing a second type of uninucleate spore. these spores, formed in the ovaries of m. mendocinus, were lanceolate ... | 1998 | 9784359 |
