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(...)

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(...)

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(...)

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(...)

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(...)

Development of an allele-specific, loop-mediated, isothermal amplification method (AS-LAMP) to detect the L1014F kdr-w mutation in Anopheles gambiae sl
A. BADOLO
Malaria control relies heavily on treated bed nets and indoor residual spraying with pyrethroid insecticides. Unfortunately, the resistance to pyrethroid insecticides, mainly due to the kdr mutation, is spreading in the main malaria vector Anopheles gambiae sl, decreasing the insecticides' efficacy. To manage the insecticide resistance rapidly(...)

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(...)

Insecticide resistance in malaria vectors in areas of seasonal malaria transmission in Burkina Faso: knock-down resistance gene distribution
A. BADOLO
Resistance to insecticide is the main concern for vectors control based on insecticides. We conducted a two-year monitoring on the resistance to insecticides of Anopheles gambiae and Anopheles funestus in five localities of Burkina Faso. The susceptibility to insecticides was performed using WHO test. The knock-down time (KDT) and after 24h mo(...)

Equivalent susceptibility of Anopheles gambiae M and S molecular forms and Anopheles arabiensis to Plasmodium falciparum infection in Burkina Faso
A. GNEME
The Anopheles gambiae sensu lato (sl) species complex in Burkina Faso consists of Anopheles arabiensis, and molecular forms M and S of Anopheles gambiae sensu stricto (ss). Previous studies comparing the M and S forms for level of infection with Plasmodium falciparum have yielded conflicting results. Mosquito larvae were sampled from natural p(...)

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.

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(...)

Detection of mutation by allele-specific loop-mediated isothermal amplification (AS-LAMP)
A. BADOLO
For effective control of pathogen-transmitting mosquitoes, precise surveillance data of mosquito distribution are essential. Recently, an increase of insecticide resistance due to the kdr mutation in Anopheles gambiae, a mosquito that transmits the malaria parasite, has been reported. With the aim of developing a simple and effective method fo(...)
