Insecticide resistance in Bemisia tabaci Gennadius (Homoptera: Aleyrodidae) and Anopheles gambiae Giles (Diptera: Culicidae) could compromise the sustainability of malaria vector control strategies in West Africa
Olivier Gnankiné , Imael H.N. Bassolé , Fabrice Chandre , Isabelle Glitho , Martin Akogbeto , Roch K. Dabiré , Thibaud Martin
Insecticides from the organophosphate (OP) and pyrethroid (PY) chemical families, have respectively, been in use for 50 and 30 years in West Africa, mainly against agricultural pests, but also against vectors of human disease. The selection pressure, with practically the same molecules year after year (mainly cotton), has caused insecticide re(...)

Weak heteroclinic solutions of anisotropic difference equations with variable exponent
A. Guiro, B. Koné, S. Ouaro
In this article, we prove the existence of heteroclinic solutions for a family of anisotropic difference equations. The proof of the main result is based on a minimization method, a change of variables and a discrete Hölder type inequality.

Metabolomic-Based Study of the Leafy Gall, the Ecological Niche of the Phytopathogen Rhodococcus Fascians, as a Potential Source of Bioactive Compounds
Aminata P Nacoulma, Olivier M Vandeputte, Manuella De Lorenzi, Mondher El Jaziri, Pierre Duez
Leafy gall is a plant hyperplasia induced upon Rhodococcus fascians infection. Previously, by genomic and transcriptomic analysis, it has been reported that, at the early stage of symptom development, both primary and secondary metabolisms are modified. The present study is based on the hypothesis that fully developed leafy gall, could represe(...)

Les héros et la Mort dans les épopées de Soundjata et de Gilgamesh
Alain Joseph Sissao
L’épopée de Soundjata constitue un récit phare sur la constitution du Mandé. Après la mort
du buffle totem de la mère du héros, qui permet de réaliser l’oracle de la naissance de
Soundjata, nous assistons à d’autres décès de proches dans la trajectoire de la maturité du
héros. Ainsi on peut noter la mort du frère qui le chassa du trône(...)

Anti-nociceptive properties in rodents and the possibility of using polyphenol-rich fractions from Sida urens L. (Malvaceae) against of dental caries bacteria
Konaté K., Zerbo P., Ouédraogo M., Dibala I.C., Hilou A., Oksana S., Brestic M., Barro N.
Sida urens L. (Malvaceae) is in flora of Asian medicinal herbs and used traditionally in West of Burkina Faso for the treatment of infectious diseases and particularly used against, dental caries bacteria, fever, pain and possesses analgesic properties. This study was conducted to reveal the antibacterial effect against dental caries bacteria(...)

«Les rapports oralité/écriture ou l’inscription de l’oralité comme fondement de l’écriture de Kourouma »
Alain Joseph Sissao
La littérature africaine a connu une longue évolution qui
permet de dire que sa longue marche a été ponctuée par des
innovations, des permanences mais aussi des ruptures. Comme le
reconnaît à juste titre Jacques Chevrier dans un travail synthétique
dans la revue Notre Librairie sur « Quarante années de littérature

Influence of engine load and fuel droplet size on performance of a CI engine fueled with cottonseed oil and its blends with diesel fuel
Tizane Daho, Gilles Vaitilingom, Salifou K. Ouiminga, Bruno Piriou, Augustin S. Zongo, Samuel Ouoba, Jean Koulidiati
In this study, favorable conditions to achieve good combustion of cottonseed oil and its blends with diesel fuel in a direct injection diesel engine have been highlighted. This has been performed by analyzing fuel droplet size distribution and determining engine specific fuel consumption and thermal efficiency, combustion parameters (ignition(...)

First report of the fruits flies, Ceratitis quinaria and Ceratitis silvestri, on yellow plum Ximenia americana in Burkina Faso, West Africa
A. BADOLO
Fruits of Ximenia americana provide oil that is used for food and cosmetics. However, oil production potentials are limited by damages caused by the fruit flies. This research focused on the identification of the harmful insects of the ripe fruits of X. americana, the measure of morphometric and demographic parameters. Damages were also determ(...)
