Control of Nosema ceranae in Honey Bees (Apis mellifera) Colonies in Eucalyptus grandis Plantations
Nosema disease is caused by the microsporidia Nosema apis and Nosema ceranae which affects the digestive functions of the honey bees (Apis mellifera). N. ceranae was described in A. mellifera in 2005 and it is associated with a high mortality of colonies in some northern hemisphere countries. In Uruguay N. ceranae is present throughout the whole territory, while N. apis is not easily found. Inevitably, Nosema disease is present in the colonies that are moved to the Eucalyptus grandis plantations, and may be the cause of high colony losses recorded there during winter. The effect of two doses of fumagillin (400 and 200 mg/ colony) and propolis (3 g/colony) over N. ceranae, and the spring population development was evaluated in an apiary located in an E. grandis plantation. Colonies that received 400 mg of fumagillin were less infected by N. ceranae than the colonies from the control group (P<0.01), whereas for the colonies that received 200 mg of fumagillin the differences (P=0.09) were marginal. Colonies that have received propolis extract did not differentiate from control colonies (P>0.10). The colonies that received 400 mg of fumagillin showed a larger population in spring than any colony from the other groups (P<0.01). This study shows that N. ceranae infectation affects the mortality and size of the colonies in winter.

La nosemosis es una enfermedad causada por los microsporidios Nosema Apis y Nosema ceranae que afecta las funciones digestivas de las abejas melíferas (Apis mellifera). N. ceranae fue descrito en A. mellifera en el año 2005 y ha sido asociado a una elevada mortandad de colonias en algunos países del hemisferio norte. En Uruguay N. ceranae está presente en todo el territorio, mientras que es muy difícil encontrar a N. apis. La nosemosis se presenta indefectiblemente en las colonias que se trasladan a las forestaciones de Eucalyptus grandis y puede ser la causa de las elevadas pérdidas registradas allí durante el invierno. En un apiario emplazado en una forestación de E. grandis se evaluó el efecto de dos dosis de fumagilina (400 y 200 mg/colonia) y del propóleos (3 g/colonia) sobre la infectación por N. ceranae y el desarrollo poblacional en primavera. Se encontró que las colonias que recibieron 400 mg de fumagilina resultaron menos infectadas por N. ceranae que las del grupo control (P<0,01), mientras que en las colonias que recibieron 200 mg de fumagilina la diferencia se dio con un nivel de significancia marginal (P=0,09). Las colonias que recibieron extracto de propóleos no se diferenciaron de las del grupo control en el nivel de nosemosis (P>0,10). En primavera las colonias que recibieron 400 mg de fumagilina presentaron una mayor población que las de los demás grupos (P<0,01). Este estudio muestra que la infectación por N. ceranae incide en la mortandad y tamaño de las colonias durante el invierno.

Nosema disease is caused by the microsporidia Nosema apis and Nosema ceranae which affects the digestive functions of the honey bees (Apis mellifera). N. ceranae was described in A. mellifera in 2005 and it is associated with a high mortality of colonies in some northern hemisphere countries. In Uruguay N. ceranae is present throughout the whole territory, while N. apis is not easily found. Inevitably, Nosema disease is present in the colonies that are moved to the Eucalyptus grandis plantations, and may be the cause of high colony losses recorded there during winter. The effect of two doses of fumagillin (400 and 200 mg/ colony) and propolis (3 g/colony) over N. ceranae, and the spring population development was evaluated in an apiary located in an E. grandis plantation. Colonies that received 400 mg of fumagillin were less infected by N. ceranae than the colonies from the control group (P<0.01), whereas for the colonies that received 200 mg of fumagillin the differences (P=0.09) were marginal.
