Vairimorpha infections in endemic Moroccan honeybees: A cross-sectional study

Biodiversity and food security on Earth would be impossible without the contribution of animal and insect pollinators, with the honeybee (Apis mellifera) being the primary agent.

However, the distribution and diversity of these insect populations, particularly native species, are increasingly threatened by various biotic and abiotic stressors, which contribute to Colony Collapse Disorder (CCD) in apiaries worldwide. A microsporidian fungus of the genus Vairimorpha (formerly Nosema)) that infects the insect gut causes the disease known as nosemosis, which is among the biotic factors potentially associated with CCD. In this study, we examined 206 samples from various apiaries in the Souss-Massa region of Morocco to assess the epidemiological status of this parasitosis in Moroccan honeybees. Spore detection and quantification of Vairimorpha spp. were performed using microscopy, while molecular techniques were employed to differentiate Vairimorpha apis from Vairimorpha ceranae. The microscopic analysis revealed a prevalence rate of 78.6%, a mean abundance of 7×105 spores/bee/apiary, and a mean infection intensity of 9×105 spores/bee/apiary. Molecular analysis indicated that V. ceranae is more prevalent than V. apis. Consequently, as observed in many other regions worldwide, V. ceranae has become invasive in native Moroccan honeybees populations, highlighting the need to consider this new ecological status in future control and conservation programs. La biodiversidad y la seguridad alimentaria en la Tierra serían imposibles sin la contribución de los animales e insectos polinizadores, como la abeja melífera (Apis mellifera), el actor principal. Sin embargo, la distribución y diversidad de esas poblaciones de insectos, especialmente las especies nativas, se ven amenazadas por muchos factores estresantes bióticos y abióticos que causan el trastorno de colapso de colonias (CCD) en colmenares de todo el mundo. Un hongo (Vairimorpha) que infecta el intestino del insecto causa la enfermedad (nosemosis), que se eleva entre los factores bióticos que podrían estar relacionados con la aparición del CCD. En el estudio actual, hemos examinado 206 muestras de diferentes colmenares en la región de Souss-Massa (Marruecos), para analizar la situación epidemiológica relacionada con la parasitosis en las abejas melíferas marroquíes. La herramienta de microscopio se utilizó para detectar y contar las esporas de Vairimorpha spp., y la herramienta molecular se utilizó para discriminar Vairimorpha apis de Vairimorpha ceranae. Los resultados del análisis microscópico mostraron una tasa de prevalencia del 78,6%, una abundancia media de 7×105 esporas/abeja/colmenar y una intensidad de infección media de 9×105 esporas/abeja/colmenar. La herramienta molecular mostró que V. ceranae es más prevalente que V. apis. Por lo tanto, como en muchos otros lugares del planeta, V. ceranae también se ha vuelto invasiva en las abejas melíferas nativas de Marruecos, lo que nos impulsa a considerar este nuevo estado ecológico en futuros programas de control y conservación.
