Item Seasonal incidence of some economic bee diseases (Varroosis, Nosemosis and American Foulbrood) in honey bee colonies of Northwestern Iran(Uludağ Üniversitesi, 2011) Lotfi, Alireza; Shahryar, Habib AghdamThe aim of this review is to inform about the status of three economic bee diseases (Varroosis, Nosemosis and American foulbrood) in an important honey producing region, eastern Azerbaijan province (Northwestern Iran). These reports are based on colonies analysed for possible occurrence of these diseases. The major bee disease in the region is varroosis. Lowest rate of varroosis spread was in spring (7.72%) and it increases in the following seasons respectively and the highest rate was occurred in March (44%). Because of cold and semi-arid climate in northwestern Iran (such as eastern Azerbaijan province), Nosema apis has lower prevalence, but it can be hazardous at spring with about 59% incidence rate. About American foulbrood (AFB) 5.8% total infection rate was observed, AFB infection was started in May with highest incidence rate (17.3% of apiaries) and finished in July with 1%. With attention to these findings and reports of local veterinary organization, varroosis as the major bee disease in this region via impairing of bee population and stability in the colony, make susceptible conditions for secondary infection with Nosema apis at next spring.
