| molecular phylogeny of the vomerifer and pedroi groups in the spissipes section of the subgenus culex (melanoconion). | members of the new world mosquito subgenus melanoconion of the genus culex are important vectors of many alphaviruses including eastern and venezuelan equine encephalitis viruses (veev). we investigated the phylogenetic relationships among nine putative species of the vomerifer and pedroi groups of the neotropical spissipes section by sequencing the internal transcribed spacer 2 (its-2) region of ribosomal dna and using phylogenetic analyses. results demonstrated that, within the spissipes secti ... | 2004 | 15311446 |
| variation in mitochondrial cytochrome c oxidase i dna can successfully identify culex (melanoconion) pedroi (diptera: culicidae) and culex (melanoconion) ribeirensis (diptera: culicidae). | culex (melanoconion) pedroisirivanakarn & belkin 1980 and culex (melanoconion) ribeirensisforattini & sallum 1985 are two morphologically very similar species of the pedroi subgroup of mosquitoes in the spissipes section of the subgenus melanoconion of the genus culex l. 1758. we carried out an analysis of the mitochondrial cytochrome c oxidase i (coi) dna variation between these two species. the recent observation of sympatric coexistence in a forested area of rio de janeiro state (brazil) trig ... | 2017 | 28011729 |
| 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 |
| studies on mosquitoes (diptera: culicidae) and anthropic environment. 8--survey of adult behaviour of spissipes section species of culex (melanoconion) in south-eastern brazil. | a study of spissipes section of culex (melanoconion) adults behaviour was carried out from august 1992 through december 1993 in human dominated (anthropic) environment in the ribeira valley, s. paulo state, brazil. by sampling at several sites it the dominance of culex ribeirensis and cx. sacchettae became evident even through a total number of ten species was recorded. those two mosquitoes showed a clear tendency to frequent the domiciliary environment where they were caught, both indoor and ou ... | 1995 | 8525318 |
| biting activity patterns of culex (melanoconion) ribeirensis in southern brazil. | the biting activity of culex ribeirensis was studied in the highland region of southern brazil and compared with data previously obtained in a lowland area of the same region. hourly sampling with human bait showed a bimodal pattern, with a greater peak in the evening crepuscular period. behavior was similar in both the highland area of lupo farm and the lowland of the ribeira valley but with a notable feature in the former. in relation to the vespertine crepuscular period, precrepuscular peaks ... | 1988 | 3193115 |
| mosquito fauna of the guapiaçu ecological reserve, cachoeiras de macacu, rio de janeiro, brazil, collected under the influence of different color cdc light traps. | the objective of the present study was to identify mosquito fauna and to evaluate whether different light bulb colors influence the attraction of light traps in the guapiaçu ecological reserve. samples were obtained monthly during the period of february, 2012 to january, 2013. centers for disease control (cdc) light traps with incandescent light bulbs and led (ultraviolet, blue, green, and red) bulbs were utilized. in total, 8,170 specimens were captured, including 59 species. the presence of an ... | 2014 | 25424268 |
