Fumagillin control of Nosema ceranae (Microsporidia:Nosematidae) infection in honey bee (Hymenoptera:Apidae) colonies in Argentina

| description | Information on the long‑term consequences of Nosema ceranae to honey bee lifespan and effectiveness of Nosema control with fumagillin is scarce and not always consistent. Our objective in this study was to evaluate the effectiveness of the antibiotic fumagillin to control N. ceranae in hives in East‑Central Argentina. Honey bee hives were assigned to 3 experimental treatments, a control group with un‑treated hives, a preventive strategy group with hives treated monthly, and a monitoring strategy group with hives treated according to a N. ceranae threshold level. Apiaries were monitored monthly during Fall‑Winter 2009 and 2010 and N. ceranae spore intensity and honey bee colony strength measures were estimated. Fumagillin‑treated colonies had reduced N. ceranae spores load in 2010 compared to control colonies. However, there was no significant difference between treated and control groups for colony strength measures including adult bee population, bee brood availability, honey, or pollen. Fumagillin treatment reduced N. ceranae intensities but had little effect on colonies. The bee population during Winter was reduced in treated as well as in control colonies. Our results clarify that fumagillin treatment should be at least reviewed and that further research should be conducted to acquire a more complete perspective of Nosemosis disease. |

Le informazioni sulle conseguenze dell'infezione da Nosema ceranae sulla durata di vita delle api da miele e sull'efficacia della fumagillina sono scarse e non sempre coerenti. Lo studio ha avuto l'obiettivo di valutare l'efficacia dell'antibiotico nel controllo della micosi in alveari delle aree orientali e centrali dell'Argentina. Gli alveari sono stati suddivisi in 3 gruppi sperimentali: un gruppo di controllo costituito da alveari non trattati, un gruppo con alveari trattati mensilmente secondo una strategia preventiva e un gruppo di monitoraggio con alveari trattati secondo il proprio livello di infezione. Gli apiari sono stati monitorati mensilmente durante la stagione autunnale e invernale 2009-2010. In questo periodo sono stati misurati il numero di spore prodotte da N. ceranae e la resistenza delle colonie di api da miele. Confrontate con il gruppo di controllo, le colonie trattate con fumagillina nel 2010 hanno mostrato una riduzione della presenza di spore di N. ceranae. Non sono state tuttavia rilevate differenze significative tra le colonie trattate con fumagillina e i gruppi di controllo per quanto concerne: resistenza delle colonie, popolazione adulta, disponibilità delle larve, produzione di miele e raccolta di polline. Si è osservato che il trattamento con l'antibiotico pur riducendo la presenza di N. ceranae ha avuto un effetto ridotto sulle colonie. La popolazione delle api è diminuita durante l'inverno nel gruppo di controllo e in quello trattato con fumagillina. I risultati ottenuti mostrano che i trattamenti a base di fumagillina dovrebbero essere rivisti e che ulteriori studi consentirebbero di acquisire una conoscenza più approfondita sulla nosemiasi.
