Three years of insecticide resistance monitoring in Anopheles gambiae in Burkina Faso: resistance on the rise?
A. BADOLO
A longitudinal Anopheles gambiae sl insecticide-resistance monitoring programme was established in four sentinel sites in Burkina Faso. For three years, between 2008 and 2010, WHO diagnostic dose assays were used to measure the prevalence of resistance to all the major classes of insecticides at the beginning and end of the malaria transmissio(...)

Detection of genetically isolated entities within the Mediterranean species of Bemisia tabaci: new insights into the systematics of this worldwide pest
BACKGROUND The taxonomy of the species complex Bemisia tabaci, a serious agricultural pest worldwide, is not well resolved yet, even though species delimitation is critical for designing effective control strategies. Based on a threshold of 3.5% mitochondrial (mtCOI) sequence divergence, recent studies have identified 28 putative species. Amon(...)

Dynamics of the invasive Bemisia tabaci (Homoptera: Aleyrodidae) Mediterranean (MED) species in two West African countries
Bemisia tabaci Gennadius is a major pest on cotton and vegetable plants in Africa. It is considered as a cryptic species complex. Identification of the most damaging species such as the Middle East–Asia Minor 1 (B biotype) and Mediterranean (MED)(which contains the Q and Africa silverleaf (ASL) biotypes) species represents an important step to(...)

Association mapping by pooled sequencing identifies TOLL 11 as a protective factor against Plasmodium falciparum in Anopheles gambiae
A. GNEME
The genome-wide association study (GWAS) techniques that have been used for genetic mapping in other organisms have not been successfully applied to mosquitoes, which have genetic characteristics of high nucleotide diversity, low linkage disequilibrium, and complex population stratification that render population-based GWAS essentially unfeasi(...)

The kdr-bearing haplotype and susceptibility to Plasmodium falciparum in Anopheles gambiae: genetic correlation and functional testing
A. GNEME
Members of the Anopheles gambiae species complex are primary vectors of human malaria in Africa. It is known that a large haplotype shared between An. gambiae and Anopheles coluzzii by introgression carries point mutations of the voltage-gated sodium channel gene para, including the L1014F kdr mutation associated with insensitivity to pyrethro(...)

Biological activities of four essential oils against Anopheles gambiae in Burkina Faso and their in vitro inhibition of acetylcholinesterase
A. BADOLO
The control of malaria is still a challenge partly due to mosquito's resistance to current available insecticides. The aim of this work was to evaluate the ovicidal, larvicidal and repellent activities of Lantana camara, Hyptis suaveolens, Hyptis spicigera and Ocimum canum essential oils against Anopheles gambiae sl according to the World Heal(...)

On the interest of ambipolar materials for gas sensing
Based on the electrochemical properties of a series of metallophthalocyanines this article shows that the phthalocyanine bearing four alkoxy groups and twelve fluorine atoms behaves approximately as those with eight fluorine atoms. This indicates that the electron-donating effect of one alkoxy group balances the electro-withdrawing effect of o(...)

Evolution of GOUNDRY, a cryptic subgroup of Anopheles gambiae s.l., and its impact on susceptibility to Plasmodium infection
A. GNEME
The recent discovery of a previously unknown genetic subgroup of Anopheles gambiae sensu lato underscores our incomplete understanding of complexities of vector population demographics in Anopheles. This subgroup, named GOUNDRY, does not rest indoors as adults and is highly susceptible to Plasmodium infection in the laboratory. Initial descrip(...)

Use of biopesticides in the perspective of chemical resistance management in Western Africa: The cases of Bemisia tabaci (Homotera: Aleyrodidae) and Anopheles...
Organic pesticides are used against agricultural pests in order to improve yields in Western Africa. Pyrethroid (PY), Organophosphates (OP) and Carbamates (CX) are the chemical pesticides mainly used. Unfortunately, these chemicals continue to select new resistant populations of B. tabaci, a polyphagous whitefly. Indirectly, the chemical resid(...)

Assessment of the flora of Burkina Faso
A. OUEDRAOGO
Sixteen years after the last comprehensive checklist of Burkina Faso, about 30% more species have become known for the country's flora. Many of these are documented in the herbarium collections of the University of Ouagadougou (OUA) and the Herbarium Senckenbergianum (FR). Nevertheless some regions and habitat types are still incompletely samp(...)

Endosymbiont metacommunities, mtDNA diversity and the evolution of the Bemisia tabaci (Hemiptera: Aleyrodidae) species complex
Bemisia tabaci, an invasive pest that causes crop damage worldwide, is a highly differentiated species complex, divided into biotypes that have mainly been defined based on mitochondrial DNA sequences. Although endosymbionts can potentially induce population differentiation, specialization and indirect selection on mtDNA, studies have largely(...)
