The order Diptera is constituted of insects that possess numerous varieties of habitats, these winged, commonly called mosquitoes, comprise a monophyletic group. Malaria transmitters in Brazil are represented by mosquitoes of the Anopheles genus, being it principal vector species Anopheles (Nyssorhynchus) darlingi Root. Collectings were accomplished in the rural area of Cuiabá in the region of Coxipó do Ouro/MT, and a total 4,773 adult mosquitoes of the genus Anopheles were obtained. The prevailing species in the collectings where An. (Nys.) darlingi with 3,905 (81.8%), considered the vector of major epidemiological expression in the region, followed by Anopheles (Nyssorhynchus) argyritarsis (Robineau-Desvoidy) 267 (5.6%) and Anopheles (Nyssorhynchus) triannulatus (Neiva & Pinto) 226 (4.7%). This report might be useful to entomological surveillance, demonstrating that the Coxipó do Ouro/MT locality might be elected as an area to be monitored, once the presence of such vector in this type of environment indicates a potential malaria transmission risk for the neighbouring regions in the state of Mato Grosso.

Abstract. This study describes ecological data obtained in a rural area in the State of Mato Grosso, including the insects belonging to the family Culicidae, especially those framed as potential vectors of tropical diseases. In 2015, we collected adult mosquitoes in fragments of forest in a rural area located in Mato Grosso Central West of Brazil. We captured 18,256 mosquitoes of the sub-families Culicinae and Anophelinae and have identified 34 species belonging to 12 genera: Aedes (1 species), Anopheles (8 species), Coquillettidia (1 species), Haemagogus (1 species), Culex (5 species), Psorophora  (5 species), Ochlerotatus (4 species), Deinocerites (1 species),  Mansonia (4 species), Sabethes (2 species), Limatus (1 species), Wyeomyia (1 species). The family Culicidae presented high richness and abundance, established by diversity indexes (Margalef α =3.26; Shannon H' = 2.09; Simpson D = 0.19) with dominance of the species Anopheles (Nyssorhyncus) darlingi Root (89.8%). This species has considerable epidemiological value, considered the main vector of malaria in Mato Grosso. Many species of mosquitoes are vectors of pathogens that cause disease in humans and domestic animals, transmitting pathogens including viruses (arboviruses), filaria worms (helminths) and protozoa.Composição de espécies e distribuição da fauna de mosquitos (Diptera: Culicidae) e sua importância para doenças transmitidas por vetores em uma área rural do centro-ocidental - Mato Grosso, BrasilResumo. Este estudo descreve dados ecológicos de uma área rural do Estado de Mato Grosso e dos insetos da família Culicidae especialmente aqueles enquadrados como vetores potenciais de doenças tropicais. Em 2015, coletamos mosquitos adultos em fragmentos de floresta em localidades de áreas rurais no Mato Grosso região Centro Oeste do Brasil. Foram capturados 18.256 exemplares alados de mosquitos das subfamílias Culicinae e Anophelinae e identificadas 34 espécies pertencentes a 12 gêneros: Aedes (1 espécie), Anopheles (8 espécies), Coquillettidia (1 espécie), Haemagogus (1 espécie), Culex (5 espécies), Psorophora (5 espécies), Ochlerotatus (4 espécies), Deinocerites (1 espécie), Mansonia (4 espécies), Sabethes (2 espécies), Limatus (1 espécie), Wyeomyia (1 espécie). A família Culicidae apresentou alta riqueza e abundância, estabelecida por índices de diversidade (Margalef α = 3.26, Shannon H' = 2.09, Simpson D = 0.19) com predominância da espécie Anopheles (Nyssorhyncus)darlingi Root (89.8%). Esta espécie tem considerável valor epidemiológico, sendo considerada o principal vetor de malária em Mato Grosso. Muitas espécies de mosquitos são vetores de patógenos que causam doenças em humanos e animais domésticos, transmitindo patógenos incluindo vírus (arboviroses), filárias (helmintos) e protozoários.

Abstract Background: The Barotse floodplains of the upper Zambezi River and its tributaries are a highly dynamic environment, with seasonal flooding and transhumance presenting a shifting mosaic of potential larval habitat and human and livestock bloodmeals for malaria vector mosquitoes. However, limited entomological surveillance has been undertaken to characterise the vector community in these floodplains and their environs. Such information is necessary as, despite substantial deployment of insecticide-treated nets (ITNs) and indoor residual spraying (IRS) against Anopheles vectors, malaria transmission persists across Barotseland in Zambia’s Western Province.Methods: Geographically extensive larval surveys were undertaken in two health districts along 102 km of transects, at fine spatial resolution, during a dry season and following the peak of the successive wet season. Larvae were sampled within typical Anopheles flight range of human settlements and identified through genetic sequencing of cytochrome c oxidase I and internal transcribed spacer 2 regions of mitochondrial and nuclear DNA. This facilitated detailed comparison of taxon-specific abundance patterns between ecological zones differentiated by hydrological controls.Results: An unexpected paucity of primary vectors was revealed, with An. gambiae s.l. and An. funestus representing < 2% of 995 sequenced anophelines. Potential secondary vectors predominated in the vector community, primarily An. coustani group species and An. squamosus. Whilst the distribution of An. gambiae s.l. in the study area was highly clustered, secondary vector species were ubiquitous across the landscape in both dry and wet seasons, with some taxon-specific relationships between abundance and ecological zones by season.Conclusions: Larval survey results imply that residual transmission of malaria in Barotseland is being mediated predominantly by secondary vector species, whose known tendencies for crepuscular and outdoor biting renders them largely insensitive to prevalent vector control methods (ITNs and IRS). Alternative interventions may be required against this vector community to further reduce transmission. Larviciding is one potential supplementary intervention, although it presents a challenge in extensive wetlands such as those found in the Upper Zambezi catchment. However, the combination of advances in remote sensing of habitats, genetic identification of local vectors, and spatial modelling present a potential opportunity to optimise targeting of aerial spraying in these environments.

Abstract Background: Environmental changes resulting from the urbanization process represent a challenge for malaria control. The majority of malaria cases in South America occur in rural areas, areas of recent occupation, mining and indigenous areas of the Amazon region. Although these areas have a significant impact on malaria cases, few entomological studies have been carried out in areas of recent occupation. This study aimed to describe the density, natural infection rate and hematophagic behavior of anopheline species in two settlements in the state of Rondonia, Brazil in order to understand how malaria transmission occurs in areas that have been settled at different times.Methods: An area of recent occupation, denominated Acampamento Fortaleza (AF), and an old settlement, denominated Projeto de Assentamento Florestal Jequitibá (PAFJ), were studied. Peridomicile collections of anopheles were carried out using the Protected Human Attraction Technique (PHAT). The risk and potential for malaria transmission were assessed using the human biting rate (HBR), sporozoite rate (SR) and the entomological inoculation rate (EIR).Results: The results confirmed that Nyssorhynchus darlingi, the main vector responsible for the transmission of malaria in the state of Rondônia, is the predominant species in the two studied locations. Although settlement of the two study sites has occurred at different times, the species richness found was low, showing that the environmental changes caused by anthropological actions probably favor the adaptation of the Ny. darlingi species. Of the 615 anopheline mosquitoes assessed, 7 (1.1%) were positive for Plasmodium infections. The EIR revealed that Ny. darlingi contributes to the transmission of malaria in both locations, since it was responsible for 0.41 infectious bites in humans at night in PAFJ and 0.16 in AF. In the two study sites, the biting occurred more frequently at dusk.Conclusions: Ny. darlingi is the principal vector found in the studied locations. Its prevalence occurs in areas of recent colonization but, even when present in a low density, this species could maintain transmission of malaria in an older settlement. The entomological information obtained in this study is important and may aid the selection of vector control actions in these locations that are considered as having a high risk of malaria transmission.

Identification of phlebotomine species in endemic areas is fundamental for analyzing the eco-epidemiological determinants of leishmaniasis. This study had the aim of investigating the phlebotomine fauna in an urban area and in a fragment of native savanna in the municipality of Pontal do Araguaia, State of Mato Grosso, Brazil, using CDC light traps. One hundred and twenty-three phlebotomine specimens belonging to seventeen different species were caught. Our results indicate synanthropic potential among vector species for leishmaniasis, such as the species Lutzomyia cruzi, L. sallesi and L. whitmani. The species L. cerradincola had never been recorded in this region, such that this is the first report of this species in the State of Mato Grosso.

Abstract. The present study had the objective of estimating the abundance and monthly frequency of vector phlebotomines for American cutaneous leishmaniasis (ACL) in the municipalities of Saquarema, Rio Bonito, Piraí and Rio Janeiro, in the state of Rio de Janeiro. Seven sites located in these municipalities were monitored over a 10 to 12-month period. Lutzomyia migonei (França) Lutzomyia (Pintomyia) fischeri (Pinto) and Lutzomyia (Nyssomyia) intermedia (Lutz & Neiva) the vectors for ACL, were recorded in all four of these municipalities. In this study, it was noteworthy that Lutzomyia (Lutzomyia) longipalpis (Lutz & Neiva) the vector of visceral leishmaniasis (VL) was registered. In addition to these vectors, three other phlebotomine species, including Lutzomyia edwardsi (Mangabeira), Lutzomyia sallesi (Galvão & Coutinho) and Lutzomyia firmatoi (Barreto, Martins & Pellegrino) were captured in peridomestic environments at the seven monitoring sites (MS) over a 1476-hour period. A total of 23,187 specimens were captured leishmaniasis vector species accounted for 99.6% of the specimens captured. Lutzomyia (N.) intermedia presented the highest abundance (SISA = 1.0) and was recorded at all monitoring sites, with the highest mean Williams values. Lutzomyia migonei was the second most abundant and was found at all sites except MS6 (SISA = 0.66). Lutzomyia (L.) longipalpis, Lutzomyia sallesi, Lutzomyia firmatoi and Lutzomyia (P.) fischeri were occasionally observed at the MS. These studies point to  the need for adoption of policies involving actions of health education, associated with the notion of environmental management and the basics concepts of the disease, as element of success of an integrated program of entomological surveillance and control of  American cutaneous leishmaniasis.Abundância e Frequência Mensal de Flebotomíneos (Diptera: Phlebotomiae) em Alguns Municípios do Estado do Rio de Janeiro, BrasilResumo. O presente estudo teve o objetivo de estimar a abundância e frequência mensal de algumas espécies de flebotomíneos incriminados como vetores da Leishmaniose Tegumentar Americana (LTA), nos municípios de Saquarema, Rio Bonito, Piraí e Rio Janeiro, no Estado do Rio de Janeiro. Sete sítios localizados nesses municípios foram monitorados ao longo de um período de 10 a 12 meses. Lutzomyia migonei (França), Lutzomyia (Pintomyia) fischeri (Pinto) e Lutzomyia (Nyssomyia) intermedia (Lutz & Neiva), foram registrados em todos os quatro municípios. Lutzomyia (Lutzomyia) longipalpis (Lutz & Neiva) vetor comprovado da Leishmaniose Visceral (LV), foi registrado. Além desses vetores, outras três espécies de flebotomíneos, incluindo Lutzomyia edwardsi (Mangabeira), Lutzomyia sallesi (Galvão & Coutinho) e Lutzomyia firmatoi (Barreto, Martins & Pellegrino) foram capturados em ambiente domiciliar nos sete sítios de monitoramento (SM) durante um período de 1.476 horas totalizando 23.187 espécimes. Espécies responsáveis pela transmissão das leishmanioses totalizaram 99,6%. L. (N.) intermedia apresentou a maior abundância (SISA = 1,0) e foi registrada em todos os SM, com os maiores valores médios de captura. Lutzomyia migonei foi a segunda mais abundante e também foi encontrada em todos os locais, exceto MS6 (SISA = 0,66). Lutzomyia (L.) longipalpis, Lutzomyia sallesi, Lutzomyia firmatoi e Lutzomyia (P.) fischeri foram ocasionalmente observadas nas SM. Esses estudos apontam para a necessidade de adoção de políticas que envolvam ações de educação em saúde, associados à noção de manejo ambiental e conceitos básicos da doença, como elemento de sucesso de um programa integrado de vigilância entomológica e controle da LTA.
