“…infestation density was not determined in previous studies. Our result on the prevalence is lower than the 100% found by Aebi et al (2016) and slightly higher than the result (89%) of Llorens-Picher et al (2017) in Ghana. This high level of infestation rate means that the parasite entered and spread in the country and could be due to the beekeeping characteristics in Burkina.…”

In Burkina Faso, beekeeping is practised throughout the country. It has many potentialities, but it faced many constraints. Sanitary constraints are less investigated and need to be elucidate for a better management of bee colonies and improvement of beekeeping. A descriptive study was conducted in Cascades region to assess the prevalence and the density of Varroa mite infestation. The method of sugar shake on adult bees was used. The overall prevalence found was 91.7% [95% CI: 83.8% - 99.5%] and the density varied from 0.3 mite/100 bees to 12.3 mites/100 bees. These results show that the Varroa mite is widespread in bee colonies and its monitoring should be considered for bee health management, which is essential for sustainable beekeeping. Advanced research is needed in a large sample area to further investigate the epidemiological aspects and the potential impact of the mite on honeybee production.

“…Although Africa is considered to be virtually N. ceranae ‐free (Strauss et al ., ; Muli et al ., ), this parasite has been reported in A. mellifera intermissa from Algeria (Higes et al ., ) and in A. mellifera adansonii from Benin (Cornelissen et al ., ). However, in the nearby Ghana, neither N. apis nor N. ceranae were detected (Llorens‐Picher et al ., ). Migratory bee eating birds like Merops apiaster may play an important role in the spread of this pathogen across continents (e.g., from Northern Africa to Southern Europe).…”

Nosema ceranae is a hot topic in honey bee health as reflected by numerous papers published every year. This review presents an update of the knowledge generated in the last 12 years in the field of N. ceranae research, addressing the routes of transmission, population structure and genetic diversity. This includes description of how the infection modifies the honey bee's metabolism, the immune response and other vital functions. The effects on individual honey bees will have a direct impact on the colony by leading to losses in the adult's population. The absence of clear clinical signs could keep the infection unnoticed by the beekeeper for long periods. The influence of the environmental conditions, beekeeping practices, bee genetics and the interaction with pesticides and other pathogens will have a direct influence on the prognosis of the disease. This review is approached from the point of view of the Mediterranean countries where the professional beekeeping has a high representation and where this pathogen is reported as an important threat.

“…Climate and temperature could also influence V. ceranae prevalence and infection 45 – 47 . While the parasite is absent in some African areas 48 , 49 , its prevalence varies from few percent to more than 60% in other continental areas 50 , 51 . Interestingly, it reaches almost 100% in Hawaiian Islands in the pacific and in the Caribbean island of Dominica 52 , 53 .…”

The microsporidian Vairimorpha (Nosema) ceranae is one of the most common parasites of the honeybee. A single honeybee carries many parasites and therefore multiple alleles of V. ceranae genes that seem to be ubiquitous. As a consequence, nucleotide diversity analyses have not allowed discriminating genetic structure of parasite populations. We performed deep loci-targeted sequencing to monitor the haplotype frequencies of genome markers in isolates from discontinuous territories, namely the tropical islands of the South West Indian Ocean. The haplotype frequency distribution corroborated the suspected tetraploidy of the parasite. Most major haplotypes were ubiquitous in the area but with variable frequency. While oceanic isolates differed from European and Asian outgroups, parasite populations from distinct archipelagoes also differed in their haplotype distribution. Interestingly an original and very divergent Malagasy isolate was detected. The observed population structure allowed formulating hypotheses upon the natural history of V. ceranae in this oceanic area. We also discussed the usefulness of allelic distribution assessment, using multiple informative loci or genome-wide analyses, when parasite population is not clonal within a single host.
