| kerteszia subgenus of anopheles associated with the brazilian atlantic rainforest:current knowledge and future challenges. | the atlantic rainforest ecosystem, where bromeliads are abundant, provides an excellent environment for kerteszia species, because these anophelines use the axils of those plants as larval habitat. anopheles (k.) cruzii and anopheles (k.) bellator are considered the primary vectors of malaria in the atlantic forest. although the incidence of malaria has declined in some areas of the atlantic forest, autochthonous cases are still registered every year, with anopheles cruzii being considered to be ... | 2007 | 17880709 |
| [anopheles cruzii larvae found in bromelias in an urban area on the brazilian coast]. | the occurrence of anopheles (kerteszia) cruzii larvae is reported for the first time in bromelias on the ground located in an urban area within the municipality of ilha bela, on the northern coast of the state of são paulo. from march 1998 to july 1999 312 immature forms of an. cruzii were captured, being that 8.6% of them were in bromelias in the urban environment, 40.1% in periurban bromelias and 51.3% in the forest. the average number of bromelias containing an. cruzii was 4.0% of the total i ... | 2009 | 19225695 |
| assessing the molecular divergence between anopheles (kerteszia) cruzii populations from brazil using the timeless gene: further evidence of a species complex. | anopheles (kerteszia) cruzii was the most important vector of human malaria in southern brazil between 1930-1960. nowadays it is still considered an important plasmodium spp. vector in southern and south-eastern brazil, incriminated for oligosymptomatic malaria. previous studies based on the analysis of x chromosome banding patterns and inversion frequencies in an. cruzii populations from these areas have suggested the occurrence of three sibling species. in contrast, two genetically distinct gr ... | 2009 | 19358734 |
| molecular evidence for the occurrence of a new sibling species within the anopheles (kerteszia) cruzii complex in south-east brazil. | anopheles cruzii (diptera: culicidae) has long been known as a vector of human and simian malaria parasites in southern and south-eastern brazil. previous studies have provided evidence that an. cruzii is a species complex, but the status of the different populations and the number of sibling species remains unclear. a recent analysis of the genetic differentiation of the timeless gene among an. cruzii populations from south and south-east brazil has suggested that the population from itatiaia, ... | 2010 | 20102614 |

| estimation of divergence time between two sibling species of the anopheles (kerteszia) cruzii complex using a multilocus approach. | anopheles cruzii is the primary human plasmodium vector in southern and southeastern brazil. the distribution of this mosquito follows the coast of the brazilian atlantic forest. previous studies indicated that an. cruzii is a complex of cryptic species. | 2010 | 20356389 |
| [anophelines of santa catarina (diptera: culicidae), brazil]. | the amazon region of brazil is endemic for malaria. in the state of santa catarina, malaria was eliminated in the 1980s. since then, a few sporadic isolated autochthonous cases have occurred. however, because malaria vectors are present within brazilian territory and extensive endemic areas exist in this country, along with the great mobility of people in tourist areas of santa catarina, there is the likelihood of reintroduction of the disease. | 2010 | 20464145 |
| salivary polytene chromosome map of anopheles darlingi, the main vector of neotropical malaria. | new photomap of anopheles (nyssorhynchus) darlingi root, 1926, is described for a population from guajará-mirim, state of rondonia, brazil. the number of sections in the previous a. darlingi reference map was maintained and new subsections were added to the five chromosome arms. breakage points of paracentric inversions had been previously incorporated into the photomap of this species. an additional inversion is reported, called 3lc, totaling 14 inversions in the a. darlingi chromosome arms. th ... | 2010 | 20682862 |
| genome-wide profiling of diel and circadian gene expression in the malaria vector anopheles gambiae. | anopheles gambiae, the primary african vector of malaria parasites, exhibits numerous rhythmic behaviors including flight activity, swarming, mating, host seeking, egg laying, and sugar feeding. however, little work has been performed to elucidate the molecular basis for these daily rhythms. to study how gene expression is regulated globally by diel and circadian mechanisms, we have undertaken a dna microarray analysis of an. gambiae under light/dark cycle (ld) and constant dark (dd) conditions. ... | 2011 | 21715657 |
| habitat suitability of anopheles vector species and association with human malaria in the atlantic forest in south-eastern brazil. | every year, autochthonous cases of plasmodium vivax malaria occur in low-endemicity areas of vale do ribeira in the south-eastern part of the atlantic forest, state of são paulo, where anopheles cruzii and anopheles bellator are considered the primary vectors. however, other species in the subgenus nyssorhynchus of anopheles (e.g., anopheles marajoara) are abundant and may participate in the dynamics of malarial transmission in that region. the objectives of the present study were to assess the ... | 2011 | 21881779 |
| mosquito (diptera: culicidae) assemblages associated with nidularium and vriesea bromeliads in serra do mar, atlantic forest, brazil. | the most substantial and best preserved area of atlantic forest is within the biogeographical sub-region of serra do mar. the topographic complexity of the region creates a diverse array of microclimates, which can affect species distribution and diversity inside the forest. given that atlantic forest includes highly heterogeneous environments, a diverse and medically important culicidae assemblage, and possible species co-occurrence, we evaluated mosquito assemblages from bromeliad phytotelmata ... | 2012 | 22340486 |
| morphometrical diagnosis of the malaria vectors anopheles cruzii, an. homunculus and an. bellator. | anopheles (kerteszia) cruzii is a primary vector of plasmodium parasites in brazil's atlantic forest. adult females of an. cruzii and an. homunculus, which is a secondary malaria vector, are morphologically similar and difficult to distinguish when using external morphological characteristics only. these two species may occur syntopically with an. bellator, which is also a potential vector of plasmodium species and is morphologically similar to an. cruzii and an. homunculus. identification of th ... | 2012 | 23148743 |
| lutzomyia umbratilis, the main vector of leishmania guyanensis, represents a novel species complex? | lutzomyia umbratilis is an important leishmania guyanensis vector in south america. previous studies have suggested differences in the vector competence between l. umbratilis populations situated on opposite banks of the amazonas and negro rivers in the central amazonian brazil region, likely indicating a species complex. however, few studies have been performed on these populations and the taxonomic status of l. umbratilis remains unclear. | 2012 | 22662146 |
| biodiversity can help prevent malaria outbreaks in tropical forests. | plasmodium vivax is a widely distributed, neglected parasite that can cause malaria and death in tropical areas. it is associated with an estimated 80-300 million cases of malaria worldwide. brazilian tropical rain forests encompass host- and vector-rich communities, in which two hypothetical mechanisms could play a role in the dynamics of malaria transmission. the first mechanism is the dilution effect caused by presence of wild warm-blooded animals, which can act as dead-end hosts to plasmodiu ... | 2013 | 23556023 |
| natural plasmodium infection in monkeys in the state of rondônia (brazilian western amazon). | simian malaria is still an open question concerning the species of plasmodium parasites and species of new world monkeys susceptible to the parasites. in addition, the lingering question as to whether these animals are reservoirs for human malaria might become important especially in a scenario of eradication of the disease. to aid in the answers to these questions, monkeys were surveyed for malaria parasite natural infection in the amazonian state of rondônia, brazil, a state with intense envir ... | 2013 | 23731624 |
| phylogeography of the neotropical anopheles triannulatus complex (diptera: culicidae) supports deep structure and complex patterns. | the molecular phylogenetic relationships and population structure of the species of the anopheles triannulatus complex: anopheles triannulatus s.s., anopheles halophylus and the putative species anopheles triannulatus c were investigated. | 2013 | 23433428 |
| evidence for the occurrence of two sympatric sibling species within the anopheles (kerteszia) cruzii complex in southeast brazil and the detection of asymmetric introgression between them using a multilocus analysis. | anopheles (kerteszia) cruzii (diptera: culicidae) is a primary vector of human and simian malaria parasites in southern and southeastern brazil. earlier studies using chromosome inversions, isoenzymes and a number of molecular markers have suggested that an. cruzii is a species complex. | 2013 | 24063651 |
| natural infection in anopheline species and its implications for autochthonous malaria in the atlantic forest in brazil. | a descriptive study was carried out in an area of the atlantic forest with autochthonous malaria in the parelheiros subdistrict on the periphery of the municipality of são paulo to identify anopheline fauna and anophelines naturally infected with plasmodium as well as to discuss their role in this peculiar epidemiological context. | 2013 | 23497493 |
| malaria outside the amazon region: natural plasmodium infection in anophelines collected near an indigenous village in the vale do rio branco, itanhaém, sp, brazil. | a few cases of plasmodium vivax malaria in which anophelines of subgenus kerteszia were incriminated as vectors have been reported outside the amazon region, in the atlantic forest. this study was carried out near an indigenous guarani village in the curucutu reserve, an environmental protection area in the municipality of itanhaém in the state of são paulo, brazil, on november 30, 2009, february 18, 2010, april 29, 2010 and may 26, 2010. mosquitoes were collected along the route to the guarani ... | 2013 | 22989665 |
| altitudinal population structure and microevolution of the malaria vector anopheles cruzii (diptera: culicidae). | in brazil, the autochthonous transmission of extra-amazonian malaria occurs mainly in areas of the southeastern coastal atlantic forest, where anopheles cruzii is the primary vector. in these locations, the population density of the mosquito varies with altitude (5-263 m above sea level), prompting us to hypothesise that gene flow is also unevenly distributed. describing the micro-geographical and temporal biological variability of this species may be a key to understanding the dispersion of mal ... | 2014 | 25511160 |
| finding connections in the unexpected detection of plasmodium vivax and plasmodium falciparum dna in asymptomatic blood donors: a fact in the atlantic forest. | a recent paper in malaria journal reported the observation of unexpected prevalence rates of healthy individuals carrying plasmodium falciparum (5.14%) or plasmodium vivax (2.26%) dna among blood donors from the main transfusion centre in the metropolitan são paulo, a non-endemic area for malaria. the article has been challenged by a group of authors who argued that the percentages reported were higher than those found in blood banks of the endemic amazon region and also that that paper had not ... | 2014 | 25168319 |
| coexistence mechanisms at multiple scales in mosquito assemblages. | species coexistence in mosquito assemblages may depend on mechanisms related to interspecific resource partitioning occurring at multiple scales. in the present work we investigated co-occurrence or spatial segregation in mosquito assemblages sharing resources at micro-habitat, habitat and landscape scales. environmental characteristics, mosquito fauna as adults and larvae were assessed along vegetation gradient in a natural landscape of tropical rainforest. huisman-olff-fresco (hof) and general ... | 2014 | 25384802 |
| malaria in the state of rio de janeiro, brazil, an atlantic forest area: an assessment using the health surveillance service. | the lethality of malaria in the extra-amazonian region is more than 70 times higher than in amazonia itself. recently, several studies have shown that autochthonous malaria is not a rare event in the brazilian southeastern states in the atlantic forest biome. information about autochthonous malaria in the state of rio de janeiro (rj) is scarce. this study aims to assess malaria cases reported to the health surveillance system of the state of rio de janeiro between 2000-2010. an average of 90 cas ... | 2014 | 25185004 |
| sex and rhythms in sandflies and mosquitoes: an appreciation of the work of alexandre afranio peixoto (1963-2013). | i will briefly discuss the work of alexandre a. peixoto on sandflies and mosquitoes, focusing initially on his contributions to the population biology and phylogenetics of brazilian populations of these important hematophagous insects. i shall also review some of his work on the underlying molecular clocks that mediate rhythmic behaviour and physiology in these species. | 2014 | 25046172 |
| effectiveness of mosquito magnet® trap in rural areas in the southeastern tropical atlantic forest. | traps are widely employed for sampling and monitoring mosquito populations for surveillance, ecological and fauna studies. considering the importance of assessing other technologies for sampling mosquitoes, we addressed the effectiveness of mosquito magnet® independence (mmi) in comparison with those of the cdc trap with co2 and lurex3® (cdc-a) and the cdc light trap (cdc-lt). field collections were performed in a rural area within the atlantic forest biome, southeastern state of são paulo, braz ... | 2014 | 25424445 |
| new records of mosquitoes (diptera: culicidae) from bolívar state in south eastern venezuela, with 27 new species for the state and 5 of them new in the country. | this is the first part of a series of studies related to mosquito ecological and biogeographic aspects. a total of 69 mosquito species (diptera: culicidae) was collected in 16 localities sampled in the gran sabana municipality, canaima national park, and venezuela. twenty-seven mosquito species are recorded for the first time from bolívar state, venezuela. five of them species are reported for the first time in venezuela: anopheles malefactor dyar and knab (1907); chagasia bonneae root (1927); c ... | 2015 | 25853113 |
| high morphological and genetic variabilities of ochlerotatus scapularis, a potential vector of filarias and arboviruses. | ochlerotatus scapularis is a potential vector of filarias and arboviruses in the neotropics. this species was once typically associated with sylvatic environments; however, cases of synanthropy and urbanization of this species have been increasingly reported in southeast brazil. despite the medical relevance of oc. scapularis, its populational variability is not yet known. to our knowledge, this is the first report describing the morphological and genetic variabilities of this species. | 2015 | 25885902 |
| wing sexual dimorphism of pathogen-vector culicids. | sexual dimorphism in animals has been studied from different perspectives for decades. in 1874 darwin hypothesized that it was related to sexual selection, and even after nearly 140 years, when additional empirical data has become available and the subject has been investigated from a contemporary viewpoint, this idea is still supported. although mosquito (culicidae) wings are of great importance as they play a sex-specific role, little is known about wing sexual dimorphism in these pathogen-vec ... | 2015 | 25890192 |
| plasmodium falciparum in the southeastern atlantic forest: a challenge to the bromeliad-malaria paradigm? | recently an unexpectedly high prevalence of plasmodium falciparum was found in asymptomatic blood donors living in the southeastern brazilian atlantic forest. the bromeliad-malaria paradigm assumes that transmission of plasmodium vivax and plasmodium malariae involves species of the subgenus kerteszia of anopheles and only a few cases of p. vivax malaria are reported annually in this region. the expectations of this paradigm are a low prevalence of p. vivax and a null prevalence of p. falciparum ... | 2015 | 25909655 |
| morphogenetic characterisation, date of divergence, and evolutionary relationships of malaria vectors anopheles cruzii and anopheles homunculus. | the mosquito species anopheles cruzii and anopheles homunculus are co-occurring vectors for etiological agents of malaria in southeastern brazil, a region known to be a major epidemic spot for malaria outside amazon region. we sought to better understand the biology of these species in order to contribute to future control efforts by (1) improving species identification, which is complicated by the fact that the females are very similar, (2) investigating genetic composition and morphological di ... | 2015 | 26256676 |
| kerteszia theobald (diptera: culicidae) mosquitoes and bromeliads: a landscape ecology approach regarding two species in the atlantic rainforest. | on the ecological scale of an organism, a homogeneous geographical landscape can represent a mosaic of heterogeneous landscapes. the bionomy of kerteszia mosquitoes can contribute to foundation landscape ecology by virtue of in the role of the configuration and composition of the habitat played in the distribution of mosquito species. thus, this study aimed: to compare the abundance of kerteszia in dense tropical rainforest, restinga and rural area, to assess the bioecological characteristics of ... | 2016 | 27686960 |
| investigating associations between biting time in the malaria vector anopheles arabiensis patton and single nucleotide polymorphisms in circadian clock genes: support for sub-structure among an. arabiensis in the kilombero valley of tanzania. | there is growing evidence that the widespread use of long-lasting insecticidal nets (llins) is prompting malaria vectors to shift their biting towards times and places where people are not protected, such as earlier in the evening and/or outdoors. it is uncertain whether these behavioural shifts are due to phenotypic plasticity and/or ecological changes within vector communities that favour more exophilic species, or involve genetic factors within vector species to limit their contact with llins ... | 2016 | 26920563 |
| mitochondrial genomes of anopheles (kerteszia) (diptera: culicidae) from the atlantic forest, brazil. | mitochondrial genome sequences are widely used as molecular markers for phylogenetic studies of mosquito species complexes, such as the anopheles albitarsis complex. except for a few studies that employed a limited number of nuclear or mitochondrial loci to address the genetic structure and species status of anopheles cruzii, anopheles bellator, and anopheles homunculus, little is known about genetic markers that can be employed in studies focusing on kerteszia species. the complete mitochondria ... | 2016 | 27146682 |
| 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 |
| diversity of mosquitoes at the itatiaia national park, state of rio de janeiro, brazil. | a temporal observational study was conducted with the aim of characterizing culicidae richness, diversity, abundance, and species similarity in fragments of atlantic forest within the itatiaia national park, state of rio de janeiro, brazil. a total of 31 mosquito species were collected in 2 sampling stations, during the day and night, and the abundance index and dominance coefficient for each species were calculated. the results showed that the culicid density was higher during the day, and the ... | 2017 | 29369024 |
