| isozyme similarity in anopheles oswaldoi sensu lato (diptera: culicidae) from the amazon region, brazil. | isozyme electrophoresis studies were conduced on anopheles oswaldoi sensu lato from three states in amazonian (brazil), including acre, where this taxon has been incriminated as a potential human malaria vector. the 13 enzymes analyzed yielded a total of 20 loci. of these, 10 were monomorphic in the three samples. diagnostic loci were not found. the measures of genetic variability showed mean number of alleles per locus between 1.5 and 2.0, percentage of polymorphic loci of 40%, and mean heteroz ... | 2005 | 15962781 |
| insight into anopheles (nyssorhynchus) (diptera: culicidae) species from brazil. | anopheles (nyssorhynchus) benarrochi s.l., anopheles (nyssorhynchus) oswaldoi s.l., and anopheles (nyssorhynchus) konderi s.l. collected in acrelandia, state of acre, brazil, were identified based on morphological characters of the male genitalia, fourth-instar larvae, and pupae. morphological variation was observed in the male genitalia of these species in comparison with specimens from other localities in brazil. dna sequence from the nuclear ribosomal second internal transcribed spacer of ind ... | 2008 | 19058619 |
| seasonal distribution of malaria vectors (diptera: culicidae) in rural localities of porto velho, rondônia, brazilian amazon. | we conducted a survey of the malaria vectors in an area where a power line had been constructed, between the municipalities of porto velho and rio branco, in the states of rondônia and acre, respectively. the present paper relates to the results of the survey of anopheles fauna conducted in the state of rondônia. mosquito field collections were performed in six villages along the federal highway br 364 in the municipality of porto velho, namely porto velho, jaci paraná, mutum paraná, vila abunã, ... | 0 | 26200969 |
| first record of anopheles konderi galvão & damasceno (diptera: culicidae) carrying eggs of dermatobia hominis (linnaeus jr.) (diptera: oestridae), from oriximiná municipality, pará, brazil. | the muscoid fly dermatobia hominis causes cutaneous myiases in mammals. females of this species use a vector to carry their eggs to the host. this note describes anopheles konderi acting as phoretic vector for d. hominis. | 2017 | 28700059 |
| sequence analysis of the second internal transcribed spacer of ribosomal dna in anopheles oswaldoi (diptera: culicidae). | sequence divergence in the second internal transcribed spacer (its2) of ribosomal dna was examined for female specimens of anopheles oswaldoi peryassu from 7 localities in south america. the lengths of its2 for all mosquitoes ranged from 348 to 356 nucleotides. after alignment of these sequences, similarity ranged from 87 to 100%. divergence was within the range of inter-specific differences for members of anopheline species complexes. therefore, specimens were placed into 4 groups that may corr ... | 1999 | 10593066 |
| systematic notes of anopheles konderi and its first record in paraná state, brazil. | we analyzed nuclear (second internal transcribed spacer and white gene) and mitochondrial (cytochrome c oxidase subunit i) data from anopheles konderi collected in the amazonian states of acre, amapá, and rondônia and the southern brazilian state of paraná. this was the first record of an. konderi in the state of paraná. we found a high degree of genetic divergence within the amazonian region and support for an. konderi as a species complex, possibly consisting of 3 species. | 2011 | 22017082 |
| systematics of the oswaldoi complex (anopheles, nyssorhynchus) in south america. | effective malaria control relies on accurate identification of those anopheles mosquitoes responsible for the transmission of plasmodium parasites. anopheles oswaldoi s.l. has been incriminated as a malaria vector in colombia and some localities in brazil, but not ubiquitously throughout its neotropical range. this evidence together with variable morphological characters and genetic differences supports that an. oswaldoi s.l. compromises a species complex. the recent fully integrated redescripti ... | 2013 | 24499562 |
| 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 |
| molecular taxonomy and evolutionary relationships in the oswaldoi-konderi complex (anophelinae: anopheles: nyssorhynchus) from the brazilian amazon region. | recent studies have shown that anopheles oswaldoi sensu lato comprises a cryptic species complex in south america. anopheles konderi, which was previously raised to synonymy with an. oswaldoi, has also been suggested to form a species complex. an. oswaldoi has been incriminated as a malaria vector in some areas of the brazilian amazon, colombia, peru and venezuela, but was not recognized as a vector in the remaining regions in its geographic distribution. the role of an. konderi as a malaria vec ... | 2018 | 29505595 |
