How natural infection by Nosema ceranae causes honeybee colony collapse.
In recent years, honeybees (Apis mellifera) have been strangely disappearing from their hives, and strong colonies have suddenly become weak and died. The precise aetiology underlying the disappearance of the bees remains a mystery. However, during the same period, Nosema ceranae, a microsporidium of the Asian bee Apis cerana, seems to have colonized A. mellifera, and it's now frequently detect...
متن کاملDoes Nosema ceranae Wipe Out Nosema apis in Turkey?
BACKGROUND The aim of this study was to determine the prevalence of the Nosema ceranae and Nosema apis among apiaries using both spore counts and multiplex PCR and the replacement of N. apis by N. ceranae in some regions of Turkey. METHODS A hundred honey bee samples were collected from 99 apiaries in 11 different locations in 2011-2012 in Turkey. Nosema infection degree from collected sample...
متن کاملHigh-level resistance of Nosema ceranae, a parasite of the honeybee, to temperature and desiccation.
Resistance of Nosema ceranae to different exposure conditions has been evaluated by using Sytox green and DAPI (4',6-diamidino-2-phenylindole) to test spore viability. High thermotolerance at 60 and 35 degrees C and resistance to desiccation were observed. However, a significant decrease in viability after freezing and a rapid degeneration of spores maintained at 4 degrees C were also detected.
متن کاملParasite-insecticide interactions: a case study of Nosema ceranae and fipronil synergy on honeybee
In ecosystems, a variety of biological, chemical and physical stressors may act in combination to induce illness in populations of living organisms. While recent surveys reported that parasite-insecticide interactions can synergistically and negatively affect honeybee survival, the importance of sequence in exposure to stressors has hardly received any attention. In this work, Western honeybees...
متن کاملRetrospective study of the Nosema ceranae infection of honey bee colonies in Iran (2004-2013)
Nosemosis is the most common disease in adult bees. Nosema apis and Nosema ceranae species are agents of important economic losses to beekeepers around the world. The severity of disease at various area is different. Previously, N. apis was observed in areas with a long winter, especially in late winter and early spring. But in recent years, disease has been reported in the warm seasons. The st...
