newly incriminated anopheline vectors of human malaria parasites in junin department, peru.sporozoite data from salivary gland dissections are presented that clearly incriminate anopheles trinkae, an. pseudopunctipennis, an. sp. near fluminensis, an. oswaldoi, an. nuneztovari and an. rangeli as vectors of malaria parasites in the rio ene valley, a hyperendemic malarious area in junin department, eastern peru. anopheles trinkae is considered the most important vector based on dissections, abundance and man-vector contact. other notes are presented on the relative abundance, bionomics a ...19873333060
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 ...19979103756
[egg morphology as an indirect method to identify anopheles benarrochi, anopheles oswaldoi and anopheles rangeli (diptera: culicidae)].in the department of putumayo in southern colombia, malaria transmission has continued in the absence of the 4 traditional latin american vector species--anopheles darlingi, anopheles nuneztovari, anopheles albimanus or anopheles trinkae. human bait collections yielded anopheles mosquitoes and a morphological variant of anopheles benarrochi, the adult females of which can easily be misidentified as anopheles oswaldoi. species identification of females of anopheles in the subgenus nyssorhynchus i ...200314968916
morphological analysis of three populations of anopheles (nyssorhynchus) nuneztovari gabaldón (diptera: culicidae) from colombia.based on the results of comparative analyses of 1,039 specimens of several progenies of anopheles nuneztovarifrom three localities in colombia, eight costal wing spot patterns were observed. patterns i and iii were the most frequent: 77.96% and 11.36%, respectively. using the diagnostic characters ratio of the length of the basal dark area of hind tarsomere ii/length of hind tarsomere ii, ratio of the length of the humeral pale spot/length of the pre-humeral dark spot, and the ratio of the lengt ...200818368239
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 ...021120360
anopheles species composition explains differences in plasmodium transmission in la guajira, northern colombia.malaria in la guajira, the most northern state of colombia, shows two different epidemiological patterns. malaria is endemic in the municipality of dibulla whereas in riohacha it is characterised by sporadic outbreaks. this study aimed to establish whether differences in transmission patterns could be attributed to different vector species. the most abundant adult female species were anopheles aquasalis, exclusive to riohacha, and anopheles darlingi, restricted to dibulla. anopheles mosquitoes w ...025411002
comparison of transmission parameters between anopheles argyritarsis and anopheles pseudopunctipennis in two ecologically different localities of bolivia.anopheles (anopheles) pseudopunctipennis is a recognized malaria vector in the slopes of the andes of bolivia. there, other species might be involved in malaria transmission and one candidate could be anopheles argyritarsis. although it is generally admitted that this species is not a malaria vector in the neotropical region, its potential role in transmission is still controversial and this situation has to be cleared, at least for bolivia. comparing the vectorial efficiency of an. pseudopuncti ...201323941216
new highland distribution records of multiple anopheles species in the ecuadorian andes.several recent climate change reviews have stressed the possibility of some malaria vectors occupying regions of higher altitudes than previously recorded. indeed, highland malaria has been observed in several african nations, possibly attributable to changes in land use, vector control and local climate. this study attempts to expand the current knowledge of the distribution of common anopheles species in ecuador, with particular attention to highland regions (> 500 m) of the andes.201121835004
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.201526223450
de novo biosynthesis of juvenile hormone iii and i by the accessory glands of the male mosquito.the role of the male accessory glands (mag) in reproduction was investigated in the mosquito aedes aegypti. mag incubated with [14c]acetate synthesized radioactively labeled jh iii, jh iii bisepoxide and methyl farnesoate. mag incubated with l-[methyl-3h]methionine synthesized [3h]jh iii and a molecule that chromatographed on hplc with jh i. analysis of mag and whole males extract by glass capillary combined gas-chromatography-selected ion monitoring mass spectrometry identified jh iii and i as ...19948205141
morphological, molecular, and chromosomal discrimination of cryptic anopheles (nyssorhynchus) (diptera: culicidae) from south america.based on similarity of male genitalia, the malaria vector anopheles trinkae faran from the eastern andean piedmont of colombia, ecuador, peru, and bolivia was determined by peyton (1993) to be a junior synonym of an. dunhami causey, then known from a single locality in amazonian brazil. following an appraisal of molecular, chromosomal, and morphological characters, we conclude herein that the 2 taxa are specifically distinct and remove an. trinkae from synonymy with an. dunhami. eggs of the 2 sp ...19989775617
