| comparative egg morphology of six species of the albimanus section of anopheles (nyssorhynchus) (diptera:culicidae). | scanning electron micrographs were used to describe and compare structures of eggs obtained from wild-caught females of 6 species of the albimanus section of anopheles (nyssorhynchus) from south america, which includes important regional vectors of human malaria. among species from the oswaldoi complex, eggs of anopheles oswaldoi (peryassu) were not differentiated from those of its sibling anopheles konderi galvão & damasceno, and eggs of the former species from brazil, ecuador, and suriname sho ... | 1997 | 9103756 |
| genetic differentiation and diagnostic loci among anopheles (nyssorhynchus) rangeli, an. (nys.) nuneztovari, and an. (nys.) dunhami (diptera: culicidae) in the brazilian amazon. | genetic variability and divergence were estimated for populations of anopheles rangeli gabaldón, cova-garcia & lopes, anopheles nuneztovari gabald6n cytotype a, and anophels dunhami causey from the brazilian amazon using isozyme electrophoresis. these species are included in the oswaldoi subgroup, subgenus nyssorhynchus (diptera: culicidae). thirteen enzymes yielded a total of 22 loci, of which 14 were monomorphic in the three species. three diagnostic loci (gpi-1, hk-1, and me) and a strong dif ... | 2002 | 12144292 |
| resurrection of anopheles goeldii from synonymy with anopheles nuneztovari (diptera, culicidae) and a new record for anopheles dunhami in the brazilian amazon. | nucleotide sequences of the internal transcribed spacer 2 (its2) rdna and partial sequences of the cytochrome coxidase subunit i (coi) mtdna and white gene ndna were obtained from specimens of anopheles nuneztovari a collected in macapá (state of amapá), obidos, prainha and almeirim (state of pará), itacoatiara and parintins (state of amazonas), brazil, and compared with previously published sequences of a. nuneztovari s.l. results of the bayesian phylogenetic analyses performed using either coi ... | 2008 | 19148419 |
| molecular comparison of topotypic specimens confirms anopheles (nyssorhynchus) dunhami causey (diptera: culicidae) in the colombian amazon. | the presence of anopheles (nyssorhynchus) dunhami causey in colombia (department of amazonas) is confirmed for the first time through direct comparison of mtdna cytochrome c oxidase i (coi) barcodes and nuclear rdna second internal transcribed spacer (its2) sequences with topotypic specimens of an. dunhami from tefé, brazil. an. dunhami was identified through retrospective correlation of dna sequences following misidentification as anopheles nuneztovari s.l. using available morphological keys fo ... | 0 | 21120360 |
| evidence of new species for malaria vector anopheles nuneztovari sensu lato in the brazilian amazon region. | anopheles nuneztovari sensu lato comprises cryptic species in northern south america, and the brazilian populations encompass distinct genetic lineages within the brazilian amazon region. this study investigated, based on two molecular markers, whether these lineages might actually deserve species status. | 2016 | 27068120 |
| implications for changes in anopheles darlingi biting behaviour in three communities in the peri-iquitos region of amazonian peru. | malaria transmission in the peri-iquitos region of amazonian peru has been designated as seasonal and hypo-endemic with recently described hyper-endemic hotspots. despite relatively recent distribution of long-lasting insecticidal bed nets (llins), malaria in amazonian peru persists and increased substantially in 2014 compared to previous years. anopheles darlingi, identified as the main malaria vector, is known for its variable behaviour depending on locality and environment. | 2015 | 26223450 |
| mitochondrial dna detects a complex evolutionary history with pleistocene epoch divergence for the neotropical malaria vector anopheles nuneztovari sensu lato. | cryptic species and lineages characterize anopheles nuneztovari s.l. gabaldón, an important malaria vector in south america. we investigated the phylogeographic structure across the range of this species with cytochrome oxidase subunit i (coi) mitochondrial dna sequences to estimate the number of clades and levels of divergence. bayesian and maximum-likelihood phylogenetic analyses detected four groups distributed in two major monophyletic clades (i and ii). samples from the amazon basin were cl ... | 0 | 22049039 |
