| the importance of anopheles albitarsis e and an. darlingi in human malaria transmission in boa vista, state of roraima, brazil. | in several districts of boa vista, state of roraima, brazil we found anopheles (nyssorhynchus) albitarsis e to be the primary vector of human malaria parasites, and during 2001-2002 it was significantly more abundant than an. darlingi (p < 0.001). other species sampled were an. (nys.) braziliensis, an. (ano.) peryassui, an. (nys.) nuneztovari, an. (nys.) oswaldoi s.l., and an. (nys.) triannulatus. as determined by the elisa technique an. darlingi had a higher overall infection rate (2.1%) compar ... | 2006 | 16830709 |
| 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 |
| 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 |
| 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 |
| abundance, behavior and entomological inoculation rates of anthropophilic anophelines from a primary colombian malaria endemic area. | in colombia for several years, the urabá-bajo cauca and alto sinú region has registered the highest numbers of malaria cases in the country. malaria vector incrimination and the characterization of entomological parameters will allow for a better understanding of malaria transmission dynamics and the design of effective vector control strategies for this region. | 2013 | 23497535 |
| 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 |
| an overview of malaria transmission from the perspective of amazon anopheles vectors. | in the americas, areas with a high risk of malaria transmission are mainly located in the amazon forest, which extends across nine countries. one keystone step to understanding the plasmodium life cycle in anopheles species from the amazon region is to obtain experimentally infected mosquito vectors. several attempts to colonise anopheles species have been conducted, but with only short-lived success or no success at all. in this review, we review the literature on malaria transmission from the ... | 2015 | 25742262 |
| 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 |
| lineage divergence detected in the malaria vector anopheles marajoara (diptera: culicidae) in amazonian brazil. | cryptic species complexes are common among anophelines. previous phylogenetic analysis based on the complete mtdna coi gene sequences detected paraphyly in the neotropical malaria vector anopheles marajoara. the "folmer region" detects a single taxon using a 3% divergence threshold. | 2010 | 20929572 |
| on the use of classic epidemiological formulae for estimating the intensity of endemic malaria transmission by vectors in the amazon. | although various reports have described entomological inoculation rates of malaria vector species, most were limited to providing descriptive field data. here, we report biting rates and survival data for two important malaria vectors in the amazon, anopheles darlingi (root) and anopheles albitarsis e (lynch-arribalzaga) (diptera: culicidae), in the state of roraima, brazil. we calculated theoretical sporozoite infection rates and critical vector biting rates for these species during 1 year, com ... | 2012 | 23950095 |
