This study mentions nosema apis. Does thymol help with nosema ceranae?

Abstract:

The aim of this study was to determine the natural occurrence of *Nosema
apis* in honey bee colonies and evaluated of *N. apis* presence in colonies
after medical treatment with fumagillin and thymol in consecutive 3 years
period. For this purpose, 208 honey bee colonies randomly selected for
detection of *N. apis* infection from Aegean ecotype of *Apis mellifera
anatolica*, one year old queen in April 2002. The colony development
performances and honey yields were evaluated through the years from 2002 to
2004. Infested colonies were classified in 3 groups as tried to be
equalized in Nosema infestation level; Fumidil-B, thymol application and
control (only sugar syrup feeding). The effects of using period of
Fumidil-B, contains fumagillin and thymol on *N. apis* infected honeybee
colonies were researched by determining winter losses, adult bees
population, brood and honey production in consecutive years. Also, control
group were impacted for same parameters. The adult bee worker population
and brood surfaces of treated in both groups (Fumidil-B and thymol) were
increased significantly (p<0.05) by years from 2002 to 2004. Honey
production of thymol group was exhibited significant (p<0.05) increase by
years, consequently. Significant decrease (p<0.05) was recorded in control
group for winter mortality, brood production, adult bee worker population
and honey yield than the other treatment groups. The study was conducted
that, observations of bee hives and regular treatment of infested colonies
supported healthy and more productive honey bees. Leaving colonies
un-medicated caused severe problems in colony production. Thymol could be
suggested to beekeeper as a qualified *Nosemiasis* prevent agent; cheap,
practical and non-toxic in hives for organic honey production. Moreover,
with using thymol, residue-free bee products could be handled economically.
