Nosema species (Nosema apis and Nosema ceranae) are parasitic living beings that causing adult honey bee diseases called Nosemosis and honey bee colonies are often infected with Nosema species. Nosema species should be identified individually and should be compared with climatic and geographic factors in apiaries because of the requirements of different conditions. The aim of this study is screen Nosema species in the apiaries that have different climatic and geographic factors and compare the incidence of Nosema species according to these factors. With the fieldworks conducted within this study, 30 adult bees from each of 169 apiaries were collected and were studied in the laboratory for the detection of Nosema species. The incidence of Nosema species according to environmental and climatic structure of the apiaries were compared statisti- cally. The difference among the selected provinces was found statistically significant in terms of Nosema infection levels by using one-way ANOVA test. At the result of this study, the determination of more Nosema ceranae infected colonies demons- trates that Nosema ceranae’s spread increased in honey bees and it began to take the place of Nosema apis. It was observed that the temperature and humidity values of the apiaries directly affect the Nosema spore density. The Pearson correlation’s tests showed that the increase of these two factors increase Nosema ceranae incidence while the decrease of these two fac- tors increase Nosema apis incidence. Therefore, it was observed that geographic and climatic differences affect the Nosema species and their infection levels.
