Contribution à l'évaluation des potentialités d'Encarsia sp.(Hymenoptera: Aphelinidae) comme agent de lutte biologique contre la mouche blanche du cotonnier, Be...
Encarsia sp. is the main solitary endoparasitoid developing on the larvae of the cotton whitefly Bemisia tabaci (Gennadius), in western Burkina Faso. The biological control potential of this parasitoid is currently under investigation. Studies of some population parameters and biological control assays have been undertaken in the laboratory an(...)

Abundance of Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) and its parasitoids on vegetables and cassava plants in Burkina Faso (West Africa)
The whitefly Bemisia tabaci is a pest of many agricultural and ornamental crops worldwide and particularly in Africa. It is a complex of cryptic species, which is extremely polyphagous with hundreds of host plants identified around the world. Previous surveys in western Africa indicated the presence of two biotypes of the invasive MED species(...)

Do natural methods count? Underreporting of natural contraception in urban Burkina Faso
B. SOURA
Natural methods of contraception were widely used in developed countries until the late 1960s to space and limit childbirth. In France, when the first contraceptive surveys were conducted, researchers noticed that the use of natural methods was underreported, and questions to correct for this bias were subsequently added. The Demographic and H(...)

Plasmodium species occurrence, temporal distribution and interaction in a child-aged population in rural Burkina Faso
A. GNEME
Malaria can be caused by five Plasmodium species. Due to their higher prevalence, much of the research concentrates on Plasmodium falciparum and Plasmodium vivax. In Burkina Faso, where P. falciparum co-exists with Plasmodium malariae and Plasmodium ovale, there is not much data about the prevalence of the latter two species across human popul(...)

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(...)

Drying of “Amelie” mango (Mangifera Indica L.): Influence of temperature on drying rates and shrinkage curves from 50 to 90 C.
D. BATHIEBO
In this study, drying rates and shrinkage curves of Amelie mango are established from 50 to 90 C and the temperature influence is investigated. Results show that drying rates are greatly influenced by drying air temperature and most of the drying process takes place during the falling drying rate period. From 50 to 90 C, drying kinetics are su(...)

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(...)

Atrial fibrillation, frequency, etiologic factors, evolution and treatment in a cardiology department in Dakar, Senegal
N. YAMEOGO
Conclusion La fibrillation atriale est fréquente en milieu hospitalier africain et concerne des sujets relativement jeunes. L'hypertension artérielle et les valvulopathies rhumatismales sont les principaux facteurs étiologiques. Le traitement reste essentiellement médicamenteux par contrôle de la fréquence cardiaque.

Screening of silent myocardial ischaemia by dobutamine stress echocardiography among type 2 diabetics at high cardiovascular risk in Senegal
N. YAMEOGO
INTRODUCTION: Diabetes is a major risk factor for coronary artery disease witch may develop insidiously. Several non-invasive methods are used to detect silent myocardial ischaemia, especially in diabetic patients at high cardiovascular risk. We project to screen, by dobutamine stress echocardiography, silent myocardial ischaemia in type 2 dia(...)

Floristic and dendrometric analysis of woodlands in the Sudano-Guinean zone: a case study of Belléfoungou forest reserve in Benin
A. OUEDRAOGO
A floristic and dendrometric analysis was carried out using 15 square plots of 1 ha each in the Belléfoungou forest reserve, located in the Sudano-Guinean zone of Benin. Species and diameter at breast height of trees were recorded. Multidimensional scaling and importance value index of species were used to identify vegetation types in the rese(...)
