Resistance to pyrethroid insecticides involving kdr mutations is widespread in Aedes aegypti (L.) (Diptera: Culicidae) and potentially could impact control efforts endemic countries. Dengue cases had been sporadic Burkina Faso for over a decade prior the 2016–2017 outbreak that resulted 15,074 suspected 36 deaths, mainly Ouagadougou. These outbreaks highlighted lack of information on numerous aspects biology, behaviour insecticide status local dengue vector populations are fundamental...
Background Recent outbreaks of dengue and other Aedes aegypti-borne arboviruses highlight the importance a rapid response for effective vector control. Data on insecticide resistance underlying mechanisms are essential outbreak preparedness, but sparse in much Africa. We investigated levels heterogeneity Ae. aegypti from contrasting settings within around Ouagadougou, Burkina Faso. Methodology/Principal findings Bioassays were performed larvae adults to diagnose prevalence resistance, assess...
Background Dengue’s emergence in West Africa was typified by the Burkina Faso outbreaks 2016 and 2017, nation’s largest to date. In both years, we undertook three-month surveys of Aedes populations or near capital city Ouagadougou, where were centered. Methodology 1200LG (urban), Tabtenga (peri-urban) Goundry (rural) localities, collected indoor outdoor resting mosquito adults, characterized larval habitats containers producing pupae reared immature stages adulthood laboratory for...
Abstract Background Outbreaks of dengue fever caused by viruses transmitted Aedes aegypti mosquitoes are repeated occurrences in West Africa. In recent years, Burkina Faso has experienced major outbreaks, most notably 2016 and 2017 when 80% cases were recorded Ouagadougou City (Central Health Region). order to better understand the ecology this vector provide information for use developing control measures, a study on characteristics container breeding sites productivity such sites, as...
Since 2000, Burkina Faso has experienced regular dengue cases and outbreaks, making an increasingly important health concern for the country. Previous studies in reported that resistance of Aedes aegypti to pyrethroid insecticides was associated with F1534C V1016I kdr mutations. The current study reports high Ae. populations insecticides, likely supported by mutations voltage-gated sodium channel, here evidenced genotyping SNPs V410L, F1534C. We also describe a new multiplex PCR-based...
Abstract Background Resistance to insecticides is spreading among populations of Aedes aegypti , the primary vector important human arboviruses. The escalating insecticide resistance poses a significant threat dengue control, with an expanding number countries affected by disease. To gain deeper insight into evolution resistance, it essential have longitudinal surveillance results, which are currently lacking, particularly from African Ae. populations. Here we report on three-years...
Background Ae . aegypti is the vector of important μ arboviruses, including dengue, Zika, chikungunya and yellow fever. Despite not being specifically targeted by insecticide-based control programs in West Africa, resistance to insecticides has been reported countries within this region. In study, we investigated status mechanisms Niamey, capital Niger. This research aims provide baseline data necessary for arbovirus outbreak prevention preparedness country. Methods Ovitraps were used...
Purpose: In the last two years Burkina Faso has experienced dengue outbreaks resulting in 2,600 cases and 21 deaths 2016, 14,944 cases, 30 2017. Lack of preparation updated information on Aedes populations hinders responses to first dengue. We carried out a three-month surveillance study collect baseline data including characterization breeding sites, susceptibility insecticides, resting feeding behaviors urban, periurban rural localities or near Ouagadougou capital city. Methods &...
The massive and inappropriate use of synthetic insecticides is causing significant increasing environmental disruption. Therefore, developing effective natural mosquitocidal compounds could be an alternative tool for malarial vector control. present study investigates the larvicidal adulticidal effect methanol acetone extracts leaves from Lippia chevalieri, multiflora, Cymbopogon schoenanthus, Lantana camara against Anopheles arabiensis, to control most widespread transmitting malaria in...
Abstract The number of dengue cases worldwide has increased ten-fold over the past decade as Aedes aegypti , primary vector this disease, thrives and expands its distribution, revealing limitations to current control methods. To better understand how Ae. evolved from a forest dwelling, generalist species highly anthropophilic urban impact contemporary gene flow on future control, we sequenced 1,206 genomes mosquitoes collected at 74 locations around globe. Here show that after evolving...
Background Since 2013, Burkina Faso has experienced regular dengue outbreaks, especially in Ouagadougou, the capital city, and Bobo-Dioulasso. Insufficient knowledge of disease some daily practices attitudes human population may contribute to proliferation vector subsequently transmission. The objective this study was assess levels its primary vector, Aedes aegypti, elucidate behavioural environmental factors associated with species. Methods A cross-sectional Knowledge, Attitude, Practice...
Recent dengue outbreaks have occurred in Ouagadougou and Bobo-Dioulasso, the two major cities of Burkina Faso. Dengue is a viral disease transmitted primarily by Aedes aegypti , highly anthropophilic mosquito that thrives human-transformed environments breeds predominantly artificial containers. In 2018, we investigated resting blood-feeding habits Ae. urban settings Ouagadougou. 3-month cross-sectional study starting August indoors outdoors adult mosquitoes were collected using Prokopack...

Abstract Malaria remains a major public health threat in Burkina Faso, as most sub-Saharan Africa countries. control relies mainly on long-lasting insecticide-treated nets (LLINs) and indoor residual spraying. In an escalating of insecticide resistance has been observed over the last decades. This study aimed to investigate underlying mechanisms Anopheles gambiae complex Ouagadougou. s.l. larvae were collected from gutters ponds, Zogona, Tampouy Tanghin, 3 localities Ouagadougou July October...
Abstract Background Outbreaks of dengue fever caused by viruses transmitted Aedes aegypti mosquitoes are repeatedly reported in West Africa. Burkina Faso has experienced major outbreaks most notably 2016 and 2017, with 80% cases recorded Ouagadougou (Central health region). In order to better understand the ecology this vector provide information for control, a study on productivity breeding sites measured abundance immature stages, resultant adult body size, site characteristics was...
Abstract Background : Since 2000, Burkina Faso has experienced regular dengue cases and outbreaks making a health concern for the country. Previous studies in reported resistance of Aedes aegypti to pyrethroid insecticides associated with F1534C V1016I kdr mutations. The current study reports high Ae. populations supported by 410L/1016I/1534C haplotypes; new multiplex PCR-based diagnostic 1534C 1016I mutations is proposed . Method s: Larvae were collected from three districts Ouagadougou...
Abstract Background: Malaria remains a major public health threat in Burkina Faso. In most sub-Saharan African countries, malaria control relies mainly on long-lasting insecticide-treated nets (LLINs) and indoor residual spray (IRS). Faso, long-term selection pressure exerted vectors by insecticide used agriculture, has been exacerbated countrywide LLINs distribution campaigns conducted every three years since 2010. The current study investigated resistance the mechanisms involved vector...
La résistance des moustiques aux insecticides chimiques conventionnels demeure une préoccupation majeure pour les programmes de lutte anti-vectorielle. Les recherches s’orientent actuellement vers l’utilisation d’alternatives naturelles, bio insecticides. L’activité insecticide certaines plantes comme le Calotropis procera (Ait.) R.br (Apocynaceae) pourrait avoir un grand intérêt dans ce domaine. Dans cette étude, nous avons effectués criblage extraits feuilles C. (aqueux, hydro-...
