Nosema disease caused by the microsporidia Nosema apis and Nosema ceranae are a honey bee pathogen parasitizing. Nosema disease symptoms include digestive and absorption disorders because the spores damage epithelial tissue and potentially causing colony death. Recently, N. ceranae has been reported as an important threat to honey bee health. Turmeric (Curcuma longa L.) Curcuma tonga L. belongs to the family Zingiberaceae and is a perennial, tropical herb. Turmeric, the powdered rhizome, is used for medicinal purposes. The aim of this study was to evaluate the potential of Turmeric (Curcuma longa L.) for the control of N. ceranae in honeybees. For the study, we infected with N. ceranae spore through dosed and fed with the turmeric extraction at difference concentration. The data show that the turmeric extraction was not toxic for bee at least at 1% and the bees fed with 0.5 % turmeric extraction had significantly lower infection rates. This data suggest that turmeric could be useful in alternative strategies for the control of N. ceranae.
