    Nosemosis (Nosema spp) is a disease that occurs in bees worldwide and causes great losses in honey productivity. The objective of the research was to determine the prevalence of Vairimorpha spp (ex Nosema spp) in the different Ecotypes of bees (Apis mellifera) of the subspecies Scutellata and Jemenitica present in the three regions of Ecuador. For this, the spore counting technique was carried out in a New Bauer chamber, the samples obtained were collected in 32 apiaries in the three regions of Ecuador; the apiaries were selected through the national registration base of the Beekeeping Health Program-2020 dependent on the General Coordination of Animal Health of the Phyto and Zoosanitary Regulation and Control Agency; in each apiary, samples were taken from 5 hives; the samples were analyzed in the AGROCALIDAD Animal Health laboratories. The prevalence of Vairimorpha was determined taking into account the three regions of Ecuador (mountains, coast and east). Particularly in the Sierra and Coast regions there was a prevalence of 6.7 and 6.3% respectively, while in the Eastern region the presence of infection was not determined in the processed samples. Highlighting that the results tend to generate a prevalence of Vairimorpha at the country level of 4.3%. Although these values are low, it is considered a latent risk, since prevalences greater than 5% require health plans to be granted to prevent the spread of the disease.
