Description
Nosema spp. and Varroa destructor are common parasites of honey bee colonies. Beekeepers routinely treat colonies with the fungicide fumagillin to control Nosema and an array of miticides to control V. destructor. Interactions between these parasites and chemical treatments are poorly understood. We allocated honey bee colonies to distinct chemical treatment regimes and monitored parasite intensities in the subsequent year. Infections of Nosema and infestations of V. destructor were positively correlated. Fumagillin was effective at mitigating Nosema intensities only over the short term, suggesting that biannual application is essential. V. destructor intensities were higher in colonies that had been previously treated with miticides, reasons for this warrant further investigation.
Nosema spp. y Varroa destructor son parásitos comunes de las colonias de abejas de miel. Los apicultores tratan rutinariamente colonias con fumagilina fungicida para controlar Nosema y una serie de acaricidas para el control de V. destructor. Las interacciones entre estos parásitos y los tratamientos químicos son poco conocidas. Asignamos colonias de abejas de la miel a diferentes regímenes de tratamiento químico y se monitorizaron distintas intensidades de parásitos en el año siguiente. Infecciones de Nosema e infestaciones de V. destructor se correlacionaron positivamente. La fumagilina fue eficaz para mitigar la intensidad de Nosema solamente a corto plazo, lo que sugiere que la aplicación bianual es esencial. Las intensidades de V. destructor fueron mayores en las colonias que habían sido tratadas previamente con acaricidas; las razones de este resultado requieren más investigación.
