ABSTRACT
Honey bees are threatened by many viruses. The deformed wing virus [DWV] is the most prevalent and is proposed by many authors to be involved in colony losses. In Algeria, no study was carried out to determine the presence of this virus. The objective of this study was to evaluate the influence of the DWV on bee colony mortalities, and its relationship with the parasitic mite Varroa destructor. The study was conducted in an apiary located in the central region of Algeria. The presence of deformed wing virus in honey bee colonies Apis mellifera intermissa in Algeria was detected by PCR. In total, 42% of the bee samples collected in the apiary were jbund positive for DWV
ABSTRACT
The objective of this work was to study the prevalence of nosemosis, a disease caused by a protozoan Nosema sp. in bee colonies Apis mellifera intermissa. Samples were taken between late February and early March on eight apiaries in 3 regions with high potential beekeeping activies [Blida, Boumerdes, Algiers]. This study showed that 44.7% of the colonies were infected with Nosema; the heavy infestation was related to the sampling period [February, March]. Apiaries in the Boumerdes region were characterized by an infection rate of 56%, this rate was significantly higher compared to rates in the apiaries of Blida and Algiers. This high prevalence of Nosema in the Boumerdes region is linked to climatic conditions [high humidity and long winters]
