Identification of Nosema ceranae in the V Region of Valparaiso, Chile

We determined innocuous doses of C. alba essential oil for honeybees.We demonstrated the antifungal activity of C. alba EO at 4 μg/bee against N. ceranae and compared it to its major monoterpenes, such as β-phellandrene (20 μg/bee), eucalyptol (20 μg/bee) and α-terpineol (20 μg/bee). The major compounds of C. alba EO, α-terpineol, eucalyptol and β-phellandrene, had significant effects against Apis mellifera infection by N. ceranae, but the antifungal effect of the complete essential oil on N. ceranae was larger than the effect of α-terpineol, eucalyptol or β- phellandrene separately, showing that C. alba oil may be a candidate for the treatment or prevention of nosemosis.
