“…Unfortunately, the Varroa mite and the small hive beetle were highly rooted in the apiaries of this country, as in the entire tropical area (Paraïso et al 2011). But this apparently has no impact on the occurrence of bee viruses, as in our study bee viruses were found even more frequently in apiaries where the Varroa mite was lacking.…”

-Samples of bees and honey from 101 apiaries were collected in the West African Republic of Benin. Visual inspection revealed high Varroa destructor and Aethina tumida infestations and low Oplostomus fuligineus infestations. A pathogen screen based on bacterial/fungal cultures or microscopic examinations revealed the absence of American and European foulbrood, chalkbrood disease, acariosis and nosemosis. However, 13 bee samples (15.47 %) were found to be infected by viruses as determined by PCR-based techniques. Acute bee paralysis virus (ABPV; 8.33 %) and Black queen cell virus (4.76 %) were the most common. From the former we found a strain with an unusual molecular signature of the capsid region, which was taxonomically positioned between ABPV and Israeli acute paralysis virus. We also discovered Lake Sinai virus (LSV; 3.57 %) for the first time in Africa. Eight honey samples collected in regions where cotton was cultivated were subjected to multi-residue and quality control analyses.honey bees / diseases / parasites / viruses / pesticide residue

Beekeeping is a very interesting activity having a positive impact on agricultural production and rural incomes. This study conducted in both municipalities of Djidja and Zogbodomey, in southern Benin, aimed at analyzing the determinants and constraints of beekeeping activities. For this purpose, a sample of 110 beekeepers randomly selected was investigated. Data about socio-economic and demographic characteristics of households as well as the difficulties in beekeeping were collected through individual interviews and focus groups. The statistical analysis done with R software version 3.1.2 have shown that beekeeping in the study area was influenced by three important socio-economic factors such asthe municipality of the producer, , literacy level and the producer belonging to a village agricultural association. The studies also revealed that the development of beekeeping faced many problems such as: the lack of financial resources, the low level European Scientific Journal January 2017 edition vol.13, No.3 ISSN: 1857 -7881 (Print) e -ISSN 1857 280 of knowledge in beekeeping techniques, the lack of extension services, the high level of parasitism and other forms of constraints as theft, bush fire. Taking into account these results will allow to pay more attention on farmers' and beekeepers situation what will be a means of alleviating of rural poverty.Keywords: Beekeeping, Apis mellifera, Determinants, Constraints, Benin RésuméL'apiculture est une activité importante ayant des retombées positives sur la production agricole et le revenu des ménages ruraux. La présente étude avait pour objectif de connaitre les déterminants et les contraintes de la pratique de l'apiculture. Elle a été conduite dans les communes de Djidja et de Zogbodomey, au centre du Bénin. A cet effet, un échantillon de 110 chefs d'exploitations constitué de façon raisonnée et aléatoire a été enquêté. Des informations sur les caractéristiques socio-économiques des ménages ainsi que les difficultés de la pratique d'apiculture ont été collectées à travers des entretiens individuels et des focus-groupes. Les analyses statistiques effectuées avec le logiciel R version 3.1.2 ont montré que la pratique de l'apiculture était influencée par trois facteurs dont la commune de provenance du producteur, le niveau d'alphabétisation et l'appartenance aux groupements de producteurs. Les études ont révélé que l'apiculture était confrontée aux problèmes de manque de moyens financiers, de non-maîtrise des techniques apicoles, de manque de vulgarisation, de manque de débouché, de parasitisme et d'autres formes de contraintes (vol, feu de brousse). La prise en compte des résultats de cette étude permettra de susciter plus l'intérêt des paysans à l'apiculture moderne et constituera un moyen pour faire reculer la pauvreté en milieu rural.

“…The bee Apis mellifera L. is an important social insect, for his role in the pollination of crops and products generated in hives. A third of the human diet depends on plants pollinated by insects especially bees (Paraïso et al 2011, Paraïso et al 2013a, Akinwadé, 2013. For over a decade, weakening and colony losses due to diseases favored by environmental factors, chemical and biological are observed globally (Vidal-Naquet, 2011).…”

Arthropods V. destructor, Acarapis woodi, Aethina tumida, Braula coeca; Galleria mellonella and Achroea grisella were identified as major pests of bees (Krauss and Page 1995; Finley et al 1996;Wilson et al 1997;Hunt, 1998;Paraïso et al 2011;Paraïso et al 2012 andParaïso et al 2013b).

Varroa sp. is one of the most important pests of world of bees A. mellifera Linnaeus (Hymenoptera: Apidae). The aim of this study is to analyze the morphological variability of Varroa so as to identify the different morphotypes of V. destructor. The study was conducted in 24 localities and 24 municipalities located in three regions (North-East, North-West and the Centre) of Benin. One to two hives were randomly selected per locality for collecting samples. In total 46 Varroa were examined in this study. Analysis of variance components was used to determine the share of the variability of morphological characteristics of V. destructor based on localities and climatic zones. Numerical classification was performed to group the populations of V. destructor based on morphological descriptors. The results show that the variability of morphological descriptors of V. destructor is usually larger at the community level than in climatic zones. In total four morphotypes of V. destructor are distinguished in Benin through the 4 variables used in the study.
