| analysis of the evolutionary forces shaping mitochondrial genomes of a neotropical malaria vector complex. | many vectors of human malaria belong to complexes of morphologically indistinguishable cryptic species. here we report the analysis of the newly sequenced complete mitochondrial dna molecules from six recognized or putative species of one such group, the neotropical anopheles albitarsis complex. the molecular evolution of these genomes had been driven by purifying selection, particularly strongly acting on the rna genes. directional mutation pressure associated with the strand-asynchronous asymm ... | 2011 | 21241811 |
| identification of a fibrinogen-related protein (fbn9) gene in neotropical anopheline mosquitoes. | malaria has a devastating impact on worldwide public health in many tropical areas. studies on vector immunity are important for the overall understanding of the parasite-vector interaction and for the design of novel strategies to control malaria. a member of the fibrinogen-related protein family, fbn9, has been well studied in anopheles gambiae and has been shown to be an important component of the mosquito immune system. however, little is known about this gene in neotropical anopheline speci ... | 2011 | 21288344 |
| hybrid sterility in crosses between two brazilian sibling species of the anopheles albitarsis complex. | complexes of cryptic species are common in several taxa and this is also the case in the anopheles genus, a group including all known human malaria vectors. the anopheles albitarsis complex comprises at least nine cryptic species, some of which are implicated as vectors of human malaria. several different types of data have been generated for this species complex such as cytogenetics, alloenzymes, morphological and feeding behavioral, hybridization experiments, rapd-pcr and rflp and mitochondria ... | 2014 | 25471342 |
| comparative mt genomics of the tipuloidea (diptera: nematocera: tipulomorpha) and its implications for the phylogeny of the tipulomorpha. | a traditionally controversial taxon, the tipulomorpha has been frequently discussed with respect to both its familial composition and relationships with other nematocera. the interpretation of internal relationships within the tipuloidea, which include the tipulidae sensu stricto, cylindrotomidae, pediciidae and limoniidae, is also problematic. we sequenced the first complete mitochondrial (mt) genome of symplecta hybrida (meigen, 1804), which belongs to the subfamily chioneinae of family limoni ... | 2016 | 27341029 |
| the mitochondrial genome of elodia flavipalpis aldrich (diptera: tachinidae) and the evolutionary timescale of tachinid flies. | tachinid flies are natural enemies of many lepidopteran and coleopteran pests of forests, crops, and fruit trees. in order to address the lack of genetic data in this economically important group, we sequenced the complete mitochondrial genome of the palaearctic tachinid fly elodia flavipalpis aldrich, 1933. usually found in northern china and japan, this species is one of the primary natural enemies of the leaf-roller moths (tortricidae), which are major pests of various fruit trees. the 14,932 ... | 2013 | 23626734 |
| ecological suitability and spatial distribution of five anopheles species in amazonian brazil. | seventy-six sites characterized in amazonian brazil revealed distinct habitat diversification by examining the environmental factors associated with the distribution and abundance of five anopheline species (diptera: culicidae) in the subgenus nyssorhynchus. these included three members of the albitarsis complex, anopheles oryzalimnetes, anopheles marajoara, anopheles janconnae; anopheles triannulatus, and anopheles goeldii. anopheles janconnae abundance had a positive correlation to water flow ... | 2013 | 23546804 |
| a new mtdna coi gene lineage closely related to anopheles janconnae of the albitarsis complex in the caribbean region of colombia. | an understanding of the taxonomic status and vector distribution of anophelines is crucial in controlling malaria. previous phylogenetic analyses have supported the description of six species of the neotropical malaria vector anopheles (nyssorhynchus) albitarsis s.l. (diptera: culicidae): an. albitarsis, anopheles deaneorum, anopheles marajoara, anopheles oryzalimnetes, anopheles janconnae and an. albitarsis f. to evaluate the taxonomic status of an. albitarsis s.l. mosquitoes collected in vario ... | 0 | 21225199 |
| malaria vectors in south america: current and future scenarios. | malaria remains a significant public health issue in south america. future climate change may influence the distribution of the disease, which is dependent on the distribution of those anopheles mosquitoes competent to transmit plasmodium falciparum. herein, predictive niche models of the habitat suitability for p. falciparum, the current primary vector anopheles darlingi and nine other known and/or potential vector species of the neotropical albitarsis complex, were used to document the current ... | 2015 | 26283539 |
| dna barcoding reveals both known and novel taxa in the albitarsis group (anopheles: nyssorhynchus) of neotropical malaria vectors. | mosquitoes belonging to the albitarsis group (anopheles: nyssorhynchus) are of importance as malaria vectors across the neotropics. the group currently comprises six known species, and recent studies have indicated further hidden biodiversity within the group. dna barcoding has been proposed as a highly useful tool for species recognition, although its discriminatory utility has not been verified in closely related taxa across a wide geographic distribution. | 2012 | 22353437 |
| mitochondrial genome sequences reveal deep divergences among anopheles punctulatus sibling species in papua new guinea. | members of the anopheles punctulatus group (ap group) are the primary vectors of human malaria in papua new guinea. the ap group includes 13 sibling species, most of them morphologically indistinguishable. understanding why only certain species are able to transmit malaria requires a better comprehension of their evolutionary history. in particular, understanding relationships and divergence times among anopheles species may enable assessing how malaria-related traits (e.g. blood feeding behavio ... | 2013 | 23405960 |
| the anopheles albitarsis complex with the recognition of anopheles oryzalimnetes wilkerson and motoki, n. sp. and anopheles janconnae wilkerson and sallum, n. sp. (diptera: culicidae). | the anopheles (nyssorhynchus) albitarsis complex includes six species: an. albitarsis, anopheles oryzalimnetes wilkerson and motoki, n. sp., anopheles marajoara, anopheles deaneorum, anopheles janconnae wilkerson and sallum, n. sp. and an. albitarsis f. except for an. deaneorum, species of the complex are indistinguishable when only using morphology. the problematic distinction among species of the complex has made study of malaria transmission and ecology of an. albitarsis s.l. difficult. conse ... | 2009 | 19876554 |
| first record of anopheles oryzalimnetes, anopheles argyritarsis, and anopheles sawyeri (diptera: culicidae) in the caatinga biome, semiarid scrubland of sergipe state, brazil. | caatinga is one of the least known biomes of brazil in relation to biodiversity. the dry condition of semiarid areas has been associated in the past with low richness of fauna and flora, not encouraging studies in this region. there is a lack of mosquito records including anophelines. thus, to investigate the biodiversity of anopheles mosquitoes in the caatinga biome, we collected immature mosquitoes in aquatic habitats in a conservation reserve located in the northwestern portion of sergipe sta ... | 2015 | 26336257 |
