Abstract:

Colony losses in honey bees; It is caused by many factors such as care and feeding errors, pesticides, bee diseases and pests, global warming and stress. Viral and some parasitic infections, which are among the bee diseases, can cause significant economic losses in bee holdings and, from time to time, colony extinction. In this study, the role of viral and parasitic factors in colony losses observed in honey bee enterprises engaged in beekeeping and making their living from this activity in Iğdır province was investigated. For this purpose, seven viral agents in 64 bee farms with colony loss; Acute bee paralysis virus (ABPV), Chronic bee paralysis virus (CBPV), Black queen cell virus (BQCV), Deformed wing virus (DWV), Sacbrood bee virus (SBV), Cashmere bee virus (KBV), Israel acute bee paralysis virus (IAPV) and two parasitic agents; Examined for Nosema apis/cerana and Varroa. For this purpose, samples of 64 bee farms with colony loss in the spring of 2021 were analyzed. ABPV, BQCV, CBPV, DWV, KBV, SBV and IAPV factors were found to be 1.56%, 76.56%, 4.68%, 50%, 1.56%, 81.25%,20.31%, respectively, in honey bee enterprises with colony loss. Nosema cerana was positive at a rate of 60.93%, and N.apise was not found. In addition, in any of the bee farms with colony loss, Varroa sp. not detected. As a result, it is thought that mixed infections are seen in bee holdings with colony loss and these mixed infections are thought to be effective in colony losses.
