Preliminary effect of an experimental treatment with Nozevit®, (a phyto-pharmacological preparation) for Nosema ceranae control

Abstract

This study evaluates the efficacy of a natural product, Nozevit, for the treatment of nosemosis caused by Nosema ceranae, in the search for alternatives to fumagillin. To this end, a field study was conducted in two apiaries at the Marchamalo Agricultural Center. Colonies naturally infected with N. ceranae were treated with this product for several weeks in autumn, while control colonies received only sugar syrup.vThe presence of N. ceranae was assessed in both hive bees and forager bees before and after treatment. Each bee was individually analyzed by PCR to determine the progression of the parasitic infection. The results showed a non-significant trend toward a reduction in the percentage of infected forager bees. However, untreated colonies exhibited an increase in the proportion of infected hive bees, which could results in lower risk of collapse, making Nozevit an alternative to treat nosemosis type C.
