Infestation level and ecological association of Nosema spp. (Microsporida: Nosematidae) and Varroa destructor (Mesostigmata: Varroidae) in honeybee colonies in south west Nigeria
The level of infestation and ecological association of Nosema spp. and Varroa destructor was studied in honeybees. The infestation rate (Mn±SD) of V. destructor ranged from 1.05 ± 0.64% to 9.02 ±4.98%. The prevalence of Nosema spp. in Osun State was found torange from low to semi-severe, while in Og...

| Sumario: | The level of infestation and ecological association of Nosema spp. and Varroa destructor was studied in honeybees. The infestation rate (Mn±SD) of V. destructor ranged from 1.05 ± 0.64% to 9.02 ±4.98%. The prevalence of Nosema spp. in Osun State was found torange from low to semi-severe, while in Ogun state, infestation leves varies from moderate to severe. However, in both states severe infestation of spores was observed. A linear negative correlation (r = -0.329) was revealed between the V. destructor and Nosema spp. in honeybees colonies. In general, all the colonies exhibited moderate to severe infection by Nosema spp. spores and 93% of the colonies had V. destructor, which necessitates urgent mitigation measures |
