| 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 |
| 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 |
| 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 |
| asymmetric effects of native and exotic invasive shrubs on ecology of the west nile virus vector culex pipiens (diptera: culicidae). | exotic invasive plants alter the structure and function of native ecosystems and may influence the distribution and abundance of arthropod disease vectors by modifying habitat quality. this study investigated how invasive plants alter the ecology of culex pipiens, an important vector of west nile virus (wnv) in northeastern and midwestern regions of the united states. | 2015 | 26076589 |
| effects of leaf litter species on macroinvertebrate community properties and mosquito yield in neotropical tree hole microcosms. | detritus quality and quantity affect macroinvertebrate productivity and distribution in many freshwater ecosystems. this study experimentally investigated the effects of leaf litter from ceiba pentandra, dipteryx panamensis, ficus yoponensis, and platypodium elegans on macroinvertebrate species composition, richness, and abundance in artificial water-filled tree holes in a lowland moist forest of panama. species composition was similar among treatments, but species richness and longevity differe ... | 1999 | 28308046 |
| mosquitoes (diptera: culicidae) from the northwestern brazilian amazon: padauari river. | the mosquito fauna (culicidae) from remote northern areas of the state of amazonas were sampled using centers for disease control and prevention, shannon, malaise, and suspended traps, together with net sweeping and immature collections. one hundred and seven collections were performed in five localities along the padauari river, state of amazonas, brazil, during june 2010. the 20,557 mosquitoes collected are distributed in 17 genera, representing 117 different species, of which four are new dis ... | 2016 | 27480098 |
