| effectiveness of mosquito magnet® trap in rural areas in the southeastern tropical atlantic forest. | traps are widely employed for sampling and monitoring mosquito populations for surveillance, ecological and fauna studies. considering the importance of assessing other technologies for sampling mosquitoes, we addressed the effectiveness of mosquito magnet® independence (mmi) in comparison with those of the cdc trap with co2 and lurex3® (cdc-a) and the cdc light trap (cdc-lt). field collections were performed in a rural area within the atlantic forest biome, southeastern state of são paulo, braz ... | 2014 | 25424445 |
| west nile virus ecology in a tropical ecosystem in guatemala. | west nile virus ecology has yet to be rigorously investigated in the caribbean basin. we identified a transmission focus in puerto barrios, guatemala, and established systematic monitoring of avian abundance and infection, seroconversions in domestic poultry, and viral infections in mosquitoes. west nile virus transmission was detected annually between may and october from 2005 to 2008. high temperature and low rainfall enhanced the probability of chicken seroconversions, which occurred in both ... | 2012 | 23149586 |
| characterization of a novel insect-specific flavivirus from brazil: potential for inhibition of infection of arthropod cells with medically important flaviviruses. | in the past decade, there has been an upsurge in the number of newly described insect-specific flaviviruses isolated pan-globally. we recently described the isolation of a novel flavivirus (tentatively designated 'nhumirim virus'; nhuv) that represents an example of a unique subset of apparently insect-specific viruses that phylogenetically affiliate with dual-host mosquito-borne flaviviruses despite appearing to be limited to replication in mosquito cells. we characterized the in vitro growth p ... | 2014 | 25146007 |
| culicidae (diptera) selection of humans, chickens and rabbits in three different environments in the province of chaco, argentina. | studies were conducted to determine the selection of humans, chickens and rabbits by culicidae in three different environments in the province of chaco, argentina. mosquitoes were collected fortnightly using cylindrical metal traps containing animal bait (chickens and rabbits). the mosquitoes were collected between june 2001-may 2002. during the same period and with the same frequency, mosquitoes biting the human operators of the traps were collected during the first 15 min of exposure within di ... | 0 | 23903970 |
| ilheus virus isolation in the pantanal, west-central brazil. | the wetlands of the brazilian pantanal host large concentrations of diverse wildlife species and hematophagous arthropods, conditions that favor the circulation of zoonotic arboviruses. a recent study from the nhecolândia sub-region of pantanal reported serological evidence of various flaviviruses, including west nile virus and ilheus virus (ilhv). according to the age of seropositive horses, at least three flaviviruses, including ilhv, circulated in the brazilian pantanal between 2005 and 2009. ... | 2013 | 23875051 |
| nhumirim virus, a novel flavivirus isolated from mosquitoes from the pantanal, brazil. | we describe the isolation of a novel flavivirus, isolated from a pool of mosquitoes identified as culex (culex) chidesteri collected in 2010 in the pantanal region of west-central brazil. the virus is herein designated nhumirim virus (nhuv) after the name of the ranch from which the mosquito pool was collected. flavivirus rna was detected by real-time rt-pcr of homogenized mosquitoes and from the corresponding c6/36 culture supernatant. based on full-genome sequencing, the virus isolate was gene ... | 2014 | 25252815 |
| comparison of automatic traps to capture mosquitoes (diptera: culicidae) in rural areas in the tropical atlantic rainforest. | in several countries, surveillance of insect vectors is accomplished with automatic traps. this study addressed the performance of mosquito magnet® independence (mmi) in comparison with those of cdc with co2 and lactic acid (cdc-a) and cdc light trap (cdc-lt). the collection sites were in a rural region located in a fragment of secondary tropical atlantic rainforest, southeastern brazil. limatus durhami and limatus flavisetosus were the dominant species in the mmi, whereas ochlerotatus scapulari ... | 0 | 24402154 |
| diversity of mosquitoes and the aquatic insects associated with their oviposition sites along the pacific coast of mexico. | the abundance, richness and diversity of mosquitoes and aquatic insects associated with their oviposition sites were surveyed along eight states of the pacific coast of mexico. diversity was estimated using the shannon index (h'), similarity measures and cluster analysis. | 2014 | 24450800 |
| wing geometry of culex coronator (diptera: culicidae) from south and southeast brazil. | the coronator group encompasses culex coronator dyar & knab, culex camposi dyar, culex covagarciai forattini, culex ousqua dyar, culex usquatissimus dyar, culex usquatus dyar and culex yojoae strickman. culex coronator has the largest geographic distribution, occurring in north, central and south america. moreover, it is a potential vector-borne mosquito species because females have been found naturally infected with several arboviruses, i.e., saint louis encephalitis virus, venezuelan equine en ... | 2014 | 24721508 |
| classification of immature mosquito species according to characteristics of the larval habitat in the subtropical province of chaco, argentina. | to classify mosquito species based on common features of their habitats, samples were obtained fortnightly between june 2001-october 2003 in the subtropical province of chaco, argentina. data on the type of larval habitat, nature of the habitat (artificial or natural), size, depth, location related to sunlight, distance to the neighbouring houses, type of substrate, organic material, vegetation and algae type and their presence were collected. data on the permanence, temperature, ph, turbidity, ... | 2011 | 21739026 |
| 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 |
| checklist of the mosquitoes of the bahamas with three additions to its fauna and keys to the adult females and fourth instars. | this up-to-date checklist of the mosquitoes of the bahamas includes 8 genera and 34 species. three species new to the bahamas are culex chidesteri, culex bisulcatus, and psorophora insularia. the status of culex antillummagnorum in the bahamas is discussed. keys to the adult females and fourth-stage larvae are given. | 2010 | 20649121 |
